The best free ebook source depends on what you mean by free. Project Gutenberg and Standard Ebooks offer permanent, generally DRM-free downloads of public-domain books. Libby and Hoopla provide current commercial ebooks as temporary library loans. DOAB and the Open Textbook Library are better choices for academic books and textbooks.
This guide separates those access models instead of presenting retailers, deal newsletters, catalogs, and true ebook libraries as if they worked the same way. Each recommendation includes its best use, formats, account requirements, permanence, DRM limitations, and the easiest way to get a book onto a Kindle, Kobo, phone, tablet, or computer.
What does “free ebook” actually mean?
Before choosing a site, identify which type of free access you need:
- Free to keep: You download a file that normally remains yours to read permanently. This usually means a public-domain, openly licensed, or rights-holder-authorized book.
- Free to borrow: You access a book through a library or controlled digital-lending service. The loan expires, and a hold or monthly borrowing limit may apply.
- Free to read online: The complete text is available in a browser, but a downloadable EPUB or PDF may not be offered.
- Free under an open license: You can read and download the book, but copying, adapting, translating, or redistributing it depends on the specific license.
- Temporarily free: An author or retailer has reduced a book’s price to zero for a limited promotion. That is a deal, not a permanent digital library.
In the United States, works first published before January 1, 1931 are currently in the public domain because their copyright terms have expired. Copyright status can differ by country, edition, translation, adaptation, cover, introduction, annotations, and other added material. The U.S. Copyright Office’s copyright overview and its duration guidance explain the important exceptions. A reputable site’s availability is not automatically a worldwide legal determination.

Free-to-keep ebook libraries
The services in this section are the best starting points when you want a file that does not expire. “Free to keep” still requires checking the rights basis, particularly if you live outside the United States or plan to reuse the text.
1. Project Gutenberg: the best general starting point for classics
Project Gutenberg is the most useful first stop for public-domain novels, poetry, plays, essays, history, philosophy, travel writing, and older nonfiction. Its homepage currently advertises more than 77,000 free ebooks and offers browser reading as well as downloads.
Open a book record and select Read now! for online reading. For an ebook file, choose EPUB3 for most modern ereaders and reading apps, or the Kindle option when the record provides one. Project Gutenberg says its EPUB and Kindle files are DRM-free; available formats can also include HTML, plain text, and PDF. See its format documentation.
Recommended Free Tools
For a newer Kindle, download EPUB3 and send it through Amazon’s Send to Kindle service. Project Gutenberg’s current reading instructions recommend this workflow. For a pre-2013 Kindle, its guidance recommends using the Kindle or MOBI download and transferring it by USB.
Best for: Austen, Dickens, Shakespeare, Twain, public-domain philosophy, older science, and classics in multiple languages.
Watch out for: Project Gutenberg’s catalog is primarily based on U.S. copyright status. A book available there may not be public domain in every country, and a later translation or annotated edition can have separate copyright.
2. Standard Ebooks: the best-quality files for classic literature
Standard Ebooks is the better choice when formatting and reading comfort matter more than having the largest possible catalog. Volunteers proofread, typeset, and structure public-domain books with consistent metadata, covers, typography, and modern ebook features.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Clear out junk files and repair common Windows errors3Fix the driver behind crashes, sound loss and screen glitchesThe project’s own production work is dedicated to the public domain through CC0, and its ebooks are distributed without DRM. Its accessibility information describes semantic XHTML, alternative text for images, accessibility metadata, and design goals aligned with WCAG 2.2 AA and EPUB Accessibility 1.1.
Choose the format that matches your device:
- EPUB: best for most ereaders and reading apps.
- AZW3: useful for direct Kindle sideloading.
- KEPUB: optimized for Kobo.
- XHTML or source files: useful for archival or technical purposes when available.
Standard Ebooks explains in its usage guide that direct browser downloads to Kindle may not add the book to the Kindle library or preserve reading position. USB transfer through the Kindle’s Books folder is the dependable AZW3 method. Its collection policy also makes clear that the project focuses on books it believes are in the U.S. public domain, generally targeting works published before January 1, 1931.
Best for: readers who want polished editions of public-domain classics on Kindle or Kobo.
Watch out for: the catalog is much smaller than Project Gutenberg’s, and U.S. public-domain status does not automatically settle the law in another country.
3. Google Books: find full-view scans and alternate editions
Google Books is more a search and digitization service than a conventional ebook library, but it is excellent for locating obscure editions and older books. It can be especially useful when you know the title or author but do not know which institution has digitized a copy.
Search for a title, open an edition, and look for Full view. If Google provides a download icon, a public-domain book will commonly be available as a PDF. Google explains that books may instead show a limited preview, snippet view, or full text made available by the publisher. If the record says Snippet view or Preview, it is not an unrestricted full-book download.
Google’s Book Search overview and free-books explanation distinguish public-domain books from books made free by rights holders and other copyright-free material. Availability can vary by country because copyright determinations are jurisdiction-sensitive.
Best for: older books, alternate scans, bibliographic research, and books that are difficult to find in EPUB form.
Watch out for: a full-view scan is often a fixed-layout PDF, not a reflowable ebook. OCR quality and edition details can vary.
Rank #2
- Our fastest Kindle Paperwhite ever – The next-generation 7“ Paperwhite display has a higher contrast ratio and 25% faster page turns.
- Ready for travel – The ultra-thin design has a larger glare-free screen so pages stay sharp no matter where you are.
- Escape into your books – Your Kindle doesn’t have social media, notifications, or other distracting apps.
- Battery life for your longest novel – A single charge via USB-C lasts up to 12 weeks.
- Read in any light – Adjust the display from white to amber to read in bright sunlight or in the dark.
4. Wikisource: multilingual books and primary documents
Wikisource is a multilingual free library containing books, speeches, poems, laws, historical documents, translations, religious texts, and other source material. It is particularly valuable for texts that are not prominent in mainstream English-language ebook catalogs.
Wikisource content must be public domain or released under a compatible free license, although a particular translation, transcription, or editorial addition can have its own terms. Its licensing policy explains the general rules.
To export a complete book, open the work’s top-level page rather than an individual chapter, then use Download or Print/export. Depending on the work, EPUB, MOBI, PDF, printable pages, or other options may be available. The offline-reading guide specifically covers EPUB and MOBI exports for multi-part works.

Watch out for: proofreading quality and export completeness vary. Some files may omit chapters if the work’s page hierarchy is incomplete.
5. Baen Free Library: authorized science-fiction and fantasy
Baen’s Free Library is different from the public-domain services above: these are publisher-authorized free titles from a commercial science-fiction and fantasy publisher. Baen says readers can read selected books online or download them in several formats without strings attached.
Open the Free Library, choose a title, and select the online-reading or download option shown on its page. Baen’s DRM information describes its general ebook catalog as DRM-free and available in several formats, although the free library is a selected subset.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Best for: science fiction, military science fiction, fantasy, and trying the first book or an older title in a series.
Watch out for: Baen is not a broad free ebook catalog. Its strength is an authorized, genre-specific selection.
6. Directory of Open Access Books: scholarly monographs
The Directory of Open Access Books (DOAB) is one of the best sources for peer-reviewed academic books, especially in the humanities and social sciences. It indexes books from trusted open-access publishers and links readers to legitimate full-text copies.
Search by title, author, subject, language, or publisher. Open a record and follow the publisher or full-text link. The actual file may be a PDF, EPUB, HTML page, or another format, because DOAB is primarily a discovery and metadata service rather than one standardized ebook store.

Best for: scholarly monographs, university-press books, academic research, and serious nonfiction.
Watch out for: the download experience and available formats vary by publisher.
7. Open Textbook Library: free college textbooks
The Open Textbook Library is the strongest choice in this list for students who need textbooks rather than novels. It currently advertises more than 1,800 open textbooks across subjects such as mathematics, science, business, economics, psychology, communication, and computer science.
Quick wins for a faster PC:

Open licensing can allow editing and redistribution, but follow the attribution requirements and confirm that the edition is current enough for your course. A free textbook may still have a paid print version, optional online platform, or newer edition.
Best for: college courses and students trying to replace expensive introductory textbooks.
Watch out for: “free” does not guarantee that the text matches your syllabus or is the latest edition.

Free ebook borrowing and controlled access
These services are the right answer for recent commercial books, rare scans, and titles that cannot legally be offered as unrestricted files. A downloaded loan is still controlled access: it can expire, require DRM-compatible software, or remain inside an app.
8. Open Library: discover and borrow hard-to-find books
Open Library combines a large bibliographic catalog with a borrowing interface for digital editions supplied through Internet Archive. It is useful for finding books, but a catalog record does not prove that a readable digital edition exists. Open Library’s reading FAQ distinguishes its millions of records from the much smaller set of books available digitally.
Use the Show only eBooks filter when searching. A Read button means the book can be read online; a Borrow button means you can borrow it after creating an account. Open Library describes one-hour browsing loans and full loans that are usually available for 14 days. It currently states a maximum of 10 active loans, and a title may have a waiting list.
For a permitted loan, choose Borrow, then read in BookReader or use the loan’s download option if EPUB or PDF is offered. DRM-protected downloads may require Adobe Digital Editions or another compatible reader, and the file stops working when the loan ends. See Open Library’s borrowing rules and loan-download guidance.
Best for: discovery, out-of-print titles, and books available through controlled digital lending.
Watch out for: Open Library is not a source of permanent, DRM-free EPUBs for every title.
9. Internet Archive: rare scans and historical material
Internet Archive’s texts collection is particularly valuable for scanned historical books, rare material, old technical manuals, government publications, and out-of-print works. Some items have unrestricted downloads; others can only be read or borrowed through BookReader or supported loan software.
Open an item and inspect the DOWNLOAD OPTIONS section. Download only formats visibly offered for unrestricted use, and check the item’s rights or access statement. If the page shows Borrow, treat the book as a loan rather than as a file you own. User-uploaded material can also differ in quality and rights status. Internet Archive explains its approach in its rights policy.
Recommended Free Tools
There is an important legal distinction here. On September 4, 2024, the U.S. Court of Appeals for the Second Circuit ruled that Internet Archive’s Free Digital Library did not qualify as fair use in a lawsuit involving unauthorized lending of in-copyright books. That decision concerns lending copyrighted commercial books; it does not make public-domain books illegal or eliminate Internet Archive’s public-domain collections. The court decision provides the relevant legal context.
Best for: archival research, scanned editions, historical material, and rare books.
Watch out for: OCR errors, library markings, damaged pages, fixed-layout scans, and controlled loans that expire.
10. Libby: current ebooks through your public library
Libby is the best option here for a current commercial ebook that you cannot find as a legal permanent download. It connects participating public libraries with ebooks, audiobooks, magazines, and other digital content. You need a library card and PIN, and catalog size, borrowing limits, loan periods, holds, and title availability are set by the library.

Loans automatically return on their due dates. The mobile app can download loans for offline reading, but libbyapp.com requires an internet connection. In the United States, most compatible ebooks can be sent to Kindle, but Kindle delivery is a title-level feature and is not universal. Libby documents these limitations in its Kindle help page, offline-reading guidance, and borrowing help.

Best for: recent novels, bestsellers, nonfiction, young-adult books, and other commercial titles.
Watch out for: a Libby download is a temporary licensed loan, not a permanent EPUB you can keep.
11. Hoopla: instant access when your library supports it
Hoopla provides library ebooks and other digital media through its app and website. It can be useful when you want immediate access and do not want to wait through a traditional hold queue.
Hoopla distinguishes between Instant titles, which are available immediately for streaming or in-app download, and Flex titles, which have a limited number of digital copies. Participating libraries set monthly borrowing limits, which reset at the beginning of each calendar month. To use it, confirm that your library participates, sign in with your library card, search for an ebook, choose Borrow, and read it in the app or download it inside the app for offline access. Hoopla explains these rules in its borrowing guide.
Best for: immediate access to library ebooks and readers whose local library has a strong Hoopla collection.
Watch out for: offline access is app-controlled, not an unrestricted EPUB or PDF file. Monthly limits and catalog availability vary by library.
12. HathiTrust Digital Library: scholarly and archival scans
HathiTrust Digital Library is particularly useful for scholarly books, university-library scans, historical works, rare editions, and full-text searching. It can help you locate a specific passage or edition even when the book is difficult to find elsewhere.
Search through the HathiTrust catalog or its digital library, then filter for Full View. A volume may offer a complete PDF, page-level PDF, browser reading, or search-only access. HathiTrust’s download documentation says that public-domain works without download restrictions can be downloaded in full, while some Google-digitized books may offer unaffiliated users only page-by-page downloads. Member-library users can have broader access, and in-copyright books may be search-only.
Access also varies by location and institutional affiliation. A University of California HathiTrust guide describes millions of Full View volumes for U.S. users, but collection statistics and access conditions change.
Best for: academic research, archival books, full-text searching, and page-accurate citations.
Watch out for: a scan may be excellent for research but awkward to read on a phone, and guest download rights may be narrower than member rights.
Which service should you choose?
- Classic novels you can keep: Start with Standard Ebooks for polished formatting, then Project Gutenberg for the largest general selection.
- A recent bestseller: Check Libby first, then Hoopla. Expect a loan rather than a permanent file.
- A beautiful Kindle edition: Try Standard Ebooks and download AZW3, or download EPUB3 from Project Gutenberg and use Send to Kindle.
- A Kobo reader: Standard Ebooks’ KEPUB files are a good starting point; EPUB also works broadly. Library compatibility depends on the title and service.
- A textbook: Use the Open Textbook Library first, then OpenStax for peer-reviewed open educational resources.
- A scholarly monograph: Search DOAB, then HathiTrust, Google Books, Internet Archive, or the OAPEN Library.
- A rare historical book: Try Internet Archive, HathiTrust, Google Books, Wikisource, and Open Library.
- Science fiction or fantasy: Baen Free Library is the strongest specialized recommendation.
- Multilingual primary texts: Wikisource is often more useful than general ebook stores.
- No account: Project Gutenberg, Standard Ebooks, Wikisource, and many public-domain records on Google Books are the easiest options.
Choose the right ebook format
| Format or method | What it means | Best use |
|---|---|---|
| EPUB | Reflowable ebook format that adapts text to screen size | Most ereaders, phones, tablets, and desktop reading apps |
| AZW3 | Kindle-oriented ebook file | Direct USB sideloading to many Kindle devices, especially from Standard Ebooks |
| KEPUB | Kobo-optimized ebook file | Kobo readers when the source offers it |
| Fixed page layout, often a scanned page image | Textbooks, illustrations, tables, archival research, and page-accurate citation | |
| MOBI | Older Kindle-oriented format | Legacy Kindle workflows when a service specifically recommends it |
| HTML or XHTML | Browser-readable web document | Immediate reading, searching, or preserving a structured source |
| In-app offline download | Local access controlled by an app and loan license | Libby and Hoopla loans; not a permanent file |
When available, EPUB is usually the most flexible choice for a modern non-Kindle device. PDF is not automatically better: it preserves the original page layout and can be uncomfortable on a small screen. For a historical scan, however, PDF may be preferable because it preserves page order, illustrations, marginalia, and the original edition.

- Standard Ebooks: Download AZW3 and copy it to the Kindle’s
Booksfolder over USB, or use EPUB with Send to Kindle. - Libby: In the U.S., open the loan, select Read With… → Kindle only when the title displays Kindle support. It is still a temporary library loan.
- Open Library or Internet Archive: A borrowed, DRM-protected EPUB may not transfer directly to Kindle. Use only the platform’s supported reader and loan method; do not bypass DRM.
Kobo
- Use KEPUB from Standard Ebooks when available.
- Otherwise download EPUB and transfer it through Kobo’s normal USB workflow or supported desktop tools.
- For library loans, follow the specific library and Kobo instructions. Availability depends on the country, library, title, and DRM system.
Phone, tablet, or computer
- Open EPUB files in Apple Books, the Kindle app, Kobo software, or another established ebook reader.
- On a desktop, an established reader such as Thorium Reader or Calibre can handle many DRM-free EPUBs.
- Read HTML books directly in a browser.
- Use the Libby or Hoopla app for their offline loans; their websites may require an internet connection.
How to tell whether a free ebook site is legitimate and safe
A polished website and a large download button do not prove that a book is lawful or safe. Before downloading, use this checklist:
- Identify the rights basis. Look for public-domain information, an open license, a rights-holder statement, or a recognized library loan.
- Prefer established sources. Nonprofits, libraries, universities, government bodies, publishers, and recognized open-access projects are safer starting points than anonymous mirrors.
- Check whether the file is permanent. A visible download can still be an expiring loan or app-controlled file.
- Read the license. Open access does not mean unrestricted commercial reuse or adaptation.
- Be suspicious of forced software. A legitimate EPUB or PDF should not require an unknown downloader, browser extension, or disabled antivirus protection.
- Watch for subscription traps. A “free download” that redirects to a paid membership, asks for unexplained card details, or repeatedly opens pop-ups is not the same as a free library service.
- Inspect the file extension. A file named
.epubshould be an ebook, not an HTML page renamed as an EPUB. - Do not use piracy mirrors or shadow libraries. This guide focuses on public-domain, open-access, rights-holder-authorized, and library-based access.
Common problems and fixes
The download button is missing
The title may be full-view but browser-only, preview-only, search-only, or a controlled loan. On Google Books, look for Full view; on HathiTrust, look for Full View; on Open Library, distinguish Read and Borrow from a catalog-only record. Open Library explicitly notes that many records do not have a readable digital copy.
The EPUB will not open
Confirm that the download completed and that the extension is really .epub. Try an established reader such as Apple Books, Kobo, Kindle software, Thorium Reader, or Calibre. If the file is DRM-protected, use the compatible application specified by the lending service rather than attempting to remove the protection.
The PDF is hard to read
That is usually a limitation of fixed-layout scans, not a broken file. Look for an EPUB or HTML version. Keep the PDF when you need the original page layout, illustrations, tables, or page numbers for citation.

Kindle rejects the file
Use EPUB3 with Send to Kindle for a current Kindle, or use Standard Ebooks’ AZW3 over USB. If you are borrowing through Libby, the title must support Kindle delivery and the U.S. feature must be available for your account and library. A DRM-protected Open Library loan may require a different supported reader.
A borrowed book expired
This is expected behavior. Reborrow it if it is available, renew it if the service and library permit renewal, or place another hold. Do not try to preserve access by bypassing the loan controls.
Useful alternatives
These services are valuable, but they use models that make them better as supplements than as replacements for the 12 primary recommendations.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsManyBooks
ManyBooks is convenient for genre browsing and independent-author freebies. Its catalog includes public-domain titles and books submitted by self-publishing authors. Its help page says downloading requires an account. Because titles can come from different sources, rights statements, quality, formats, and availability may vary more than on a library or university repository.
National Academies Press
National Academies Press is excellent for science, engineering, medicine, transportation, and public-policy reports. It says more than 8,500 titles are available and that almost all can be downloaded free by chapter or as a complete PDF, while specially formatted commercial ebooks may still be sold.
OpenStax
OpenStax publishes peer-reviewed open educational resources and free textbooks in areas including mathematics, science, business, and social sciences. Check the license shown for each book because licensing and publication details can change.
BookBub
BookBub is useful for finding temporary free and discounted retailer promotions. It is not a library: BookBub says free offers may be limited-time and prices can change without notice. Use it to discover deals, not as a permanent public-domain collection.

Can I download free ebooks legally?
Yes. Legal sources include public-domain projects such as Project Gutenberg and Standard Ebooks, openly licensed publishers and repositories such as DOAB and the Open Textbook Library, rights-holder-authorized catalogs such as Baen’s Free Library, and library services such as Libby and Hoopla. Check the source’s rights statement and remember that copyright can differ by country and edition.
Are free library ebooks permanent downloads?
No. Libby, Hoopla, Open Library loans, and many Internet Archive loans are temporary. You may be able to download a loan for offline reading, but the file or app access expires when the loan ends.
Can I read Project Gutenberg books on a Kindle?
Yes. For a newer Kindle, download EPUB3 from the book record and use Amazon’s Send to Kindle. Project Gutenberg’s current instructions recommend the Kindle/MOBI option and USB transfer for some older Kindle devices.
Is Standard Ebooks better than Project Gutenberg?
They serve different priorities. Standard Ebooks usually offers more polished typography, metadata, accessibility features, and device-specific formats such as AZW3 and KEPUB. Project Gutenberg has a larger and more varied catalog and often offers more format choices. Try Standard Ebooks for presentation and Project Gutenberg for selection.

No. A Libby title is a licensed library loan. It can be read offline in the app, or sent to Kindle in the U.S. when the title supports that option, but access ends when the loan expires.
Why does Open Library ask me to borrow a book?
Open Library has both catalog records and digital editions. A record may have no digital copy, may be readable only online, or may be available as a time-limited loan. A Borrow button indicates controlled access rather than a permanent, unrestricted download.
Which free ebook sites have textbooks?
Start with the Open Textbook Library and OpenStax. For scholarly monographs, use DOAB. National Academies Press is particularly useful for science, engineering, medicine, and policy reports.
What is the difference between EPUB and PDF?
EPUB is generally reflowable, so text adjusts to the screen and font size. PDF preserves a fixed page layout, which is useful for textbooks, illustrations, scans, and citation but can be difficult to read on a phone. Use EPUB for ordinary ebook reading and PDF when the page design matters.
Why will my Kindle not open a downloaded EPUB?
Use Send to Kindle rather than copying the EPUB directly to the device, or download an AZW3 file when the source provides one. Standard Ebooks recommends AZW3 for direct USB transfer. A DRM-protected library loan may not be transferable as an ordinary file and must be opened through the service’s supported method.
Are all public-domain editions free to reuse?
No. Public-domain status applies to a particular work or edition and can vary by country. A newer translation, introduction, annotation, cover, restored text, or typographic redesign may have separate copyright even when the underlying original work is public domain.
The Bottom Line
Use Project Gutenberg or Standard Ebooks for classic books you can keep, Libby or Hoopla for current commercial books through a library, Internet Archive, HathiTrust, or Google Books for rare scans, DOAB for scholarly books, and the Open Textbook Library or OpenStax for coursework. The key question is not simply whether an ebook is free, but whether it is a permanent download, an open-licensed file, an online copy, or a loan that will expire.
