A dealer’s catalogue entry, ownership history or sale record does not by itself prove that the dealer took part in an excavation. To establish excavation participation, look for contemporaneous authorization and field records that name the person, identify the site and dates, and describe a defined function. Then corroborate those records with independent institutional, museum, archive and lawful-acquisition documents. If the available records show only later buying or selling, the defensible conclusion is that a trading role is documented—not excavation participation.
What “documented participation” should mean
Start by defining the claim precisely. “The dealer was involved in the excavation” can mean several different things: the person held or shared a permit, joined the field mission, funded the work, supplied equipment, acted as a local intermediary, purchased finds after excavation, or later described an object in a catalogue. Those functions have different documentary footprints and must not be treated as interchangeable.
A strong finding links the named person to an authorized excavation through a dated primary record. The record should identify the site or concession, the excavation authority, the relevant period and the person’s function. A later catalogue or dealer statement can point you toward such records, but it is not a substitute for them.

Records that can prove or disprove the claimed role
The exact records depend on the country, period, site and institution. Seek the documents below in roughly this order, while recording who created each item, when, and where it is held.
| Record | What it can establish | Limits to note |
|---|---|---|
| Permit, concession or excavation license | Whether the work was authorized; the concession holder, mission, site, dates and conditions. | A person not named on the permit may still have had a documented subordinate role, but the permit alone does not prove daily field participation. |
| Mission roster, staff list or appointment letter | Whether the person was formally assigned to the project and in what capacity. | Titles may be vague; check duties, dates and the issuing institution. |
| Excavation diary, daybook and field notebook | Contemporaneous presence, activities, trenches, dates and decisions in the field. | Survival and access vary; an absent diary is not proof that a person was absent. |
| Daily find register, context sheets and field numbers | The object’s excavation context, identifier, date and responsible excavator or recorder. | A field number must be followed into later deposit, export and custody records. |
| Official correspondence | Communications among the archaeological service, mission, museum, funders and named individuals. | Correspondence may repeat an unverified assertion; identify the author and recipient. |
| Preliminary and final excavation reports | Published or submitted account of the mission, personnel, methods, finds and disposition. | Reports can omit assistants, suppliers or later changes; compare them with field records. |
| Archive or museum deposit record | Where the field archive and finds were deposited and under whose authority. | Deposited objects may arrive with incomplete documentation. |
| Export permits, allocation records and accession registers | Lawful movement, division or institutional custody after excavation. | They document a later legal or administrative step, not necessarily who excavated. |
| Dealer ledgers, invoices and catalogues | A transaction, supplier, price, description or later ownership claim. | They normally document trade rather than authorization or fieldwork. |
UNESCO’s recommendation says national archaeological services should, “as far as possible, make their documentation and reserve collections of archaeological material readily available for inspection and study to excavators and qualified experts.” Access may still be limited by national law, privacy, conservation, security or archival policy.
Separate excavation work from later trade
Permit holder or mission member
A permit or concession names the authority responsible for the excavation. A roster, appointment letter, diary entry or report can show that another person worked under that authority. The strongest evidence states both the person and the function—for example, recorder, conservator, surveyor or field archaeologist—rather than merely listing a name.

Funder, supplier or intermediary
Funding, transport, equipment supply and local introductions may appear in correspondence or financial files. They can explain access to a site without proving that the person excavated, handled finds in the field or held a legal concession. Describe the role exactly as the records do.
Buyer or dealer after excavation
An invoice, catalogue, ownership history or dealer register can document a later transaction. It does not establish that the same person was present during excavation or had authority to remove an object. A claim that an object was “found by” or “from the excavations of” a dealer requires a separate primary record tying the person to the mission.
Retrospective claimant
Memoirs, interviews and later catalogue notes may preserve useful leads, especially when they identify a permit, expedition or archive. Because they were created after the events and may rely on memory or self-interest, test them against contemporaneous records and independent institutional holdings.

A step-by-step verification workflow
- Capture the exact claim. Save the catalogue page, photograph or quotation. Record the person’s full name and variant spellings, the object, site, expedition, dates and claimed function. Mark whether the wording is a direct quotation or a paraphrase.
- Identify the excavating authority. Find the national archaeological service, concession holder, excavation director, sponsoring institution and mission dates. Official reports and museum records often provide the first reliable names and identifiers.
- Locate the permit and concession file. Request the authorization, concession terms, renewals, team lists and reports from the responsible archaeological service, archive, museum or excavation institution. Note the country’s access rules and the archive’s reference numbers.
- Request the field archive. Ask specifically for diaries or daybooks, daily find registers, context sheets, photographs, plans, correspondence, preliminary reports, final reports and records showing where finds and documentation were deposited. A general request for “provenance” may miss the field documents that establish participation.
- Search for the person’s defined role. Check every occurrence of the name, including initials, titles and language variants. Prefer a dated record that links the person to the site, authority and activity. A name in a sales history should be treated as a trade reference unless a field record connects it to the excavation.
- Trace the object independently. Compare the excavation or find number, context description, measurements, photographs, markings and date with museum accession or deposit records, allocation decisions, export permits and successive transaction documents. Follow the chain from field record to present custody rather than starting with the dealer’s description.
- Corroborate with independent holders. Compare the excavation archive with national-service files, institutional reports, museum registers, correspondence and contemporary publications. Record whether one account simply copies another; multiple repetitions of a single dealer statement are not independent confirmation.
- Document gaps and conflicts. List what you requested, what was available, the date and creator of each source, and any disagreement. State “the role is not documented in the records located” when that is all the evidence supports. Do not convert an inaccessible or missing file into a claim that the person was not involved.
How to weigh conflicting evidence
Use five practical comparison axes. They are an analytical method, not a formal UNESCO or ICOM scoring system.
| Axis | Stronger indication | Weaker indication |
|---|---|---|
| Directness | The record explicitly names the person and role in the excavation. | The record mentions only the object, a later owner or an unattributed story. |
| Contemporaneity | Created during the excavation or soon afterward as an official report. | Written decades later from memory or for a sales catalogue. |
| Independence | Separate archives or authors reach the same conclusion without copying. | Several sources repeat one dealer’s wording or a single undocumented catalogue. |
| Specificity | Names the site, concession, dates, authority and function. | Uses broad phrases such as “associated with the expedition.” |
| Continuity | The excavation identifier can be followed through deposit, allocation, export and custody. | The object appears only in a later inventory with no field identifier. |
Converging records score well across all five axes. A single highly specific document can be important, but check its provenance and authorship before treating it as conclusive. A conflict should be reported rather than silently resolved in favor of the most convenient account.
Object documentation is not excavation documentation
ICOM’s Object ID standard helps create a consistent description and identification record. Its categories include object type; materials and techniques; measurements; inscriptions or markings; distinguishing features; title; subject; date or period; and maker. ICOM describes a process of photographing the object, recording these categories, writing a short description and keeping the documentation securely.

That standard is valuable for comparing an object across museum, archive and transaction records, but it does not establish who excavated it, whether a permit existed or whether a dealer was part of a field mission. ICOM reports that development of Object ID drew “over 1,000 responses” from organizations in “84 countries”; those figures describe the standard’s development, not the frequency of documented dealer participation.
Use Object ID fields to test whether two records describe the same object. Use permits, field registers, diaries and institutional reports to test the excavation claim.

What dealer records can—and cannot—show
Article 10(a) of UNESCO’s 1970 Convention describes a measure States Parties should apply as appropriate for each country: dealers should “maintain a register recording the origin of each item of cultural property, names and addresses of the supplier, description and price of each item sold.” The provision also addresses informing purchasers about relevant export prohibitions.

This is not a guarantee that a particular dealer file exists, survives or is open to the public. The Convention entered into force on 24 April 1972; domestic implementation, reservations and later national legislation determine what was required in a particular country and period. A dealer register can document a supplier, origin statement and sale price, but those entries may reflect information supplied by someone else and do not replace an excavation permit or field archive.
UNESCO’s excavation recommendation also says, “Each Member State should clearly define the principles which hold good on its territory in regard to the disposal of finds from excavations.” Therefore, check the law and allocation practice applicable to the site and date before labeling an export, sale or retention lawful or unlawful.
Archive quality and missing documentation
Finds can be deposited in a museum without the complete archive that gives them archaeological meaning. ICOM’s guidance on archaeological archives warns: “Although they may deposit the artefacts with a museum in the country where the excavations are undertaken there are instances where inadequate or no documentation accompanies these artefacts.” Treat that as a reason to investigate the archive, not as proof of illicit excavation.
Ask whether the institution holds the field notebooks, plans, photographs, registers and correspondence separately from the objects. Establish whether records were transferred, lost, restricted, digitized under another reference number or retained by a former mission member. State the practical effect of any gap: for example, an object may be identifiable by appearance but impossible to connect securely to a documented trench or excavation date.
How to write a defensible conclusion
Use narrow language that matches the evidence:
- Documented participation: “A 1934 concession file and contemporaneous mission roster name the person as a member of the excavation team; the diary and final report record the same role.”
- Documented trade only: “The available records document the person’s purchase and later sale of the object, but do not identify the person in the excavation authorization or field archive.”
- Unresolved: “The catalogue claims an excavation connection, but the permit and field records were not available for inspection, so participation cannot be confirmed.”
- Conflicting accounts: “A later dealer statement names the person as an excavator, while the contemporary roster lists a different role; the conflict remains unresolved.”
Identify the country, excavation, object, dates and records reviewed. Explain whether each source is contemporary or retrospective, independent or derivative, and complete or partial. Avoid declaring that a person “was not involved” when the archive is incomplete; say only what the located records establish.
Questions to put to an archive or museum
- What is the reference number for the excavation permit or concession, and who was named as holder?
- Are mission rosters, appointment letters, diaries, daybooks and daily find registers preserved?
- Does the person’s full name or any known variant appear in those records, and in what role?
- Can the object’s field or excavation number be matched to a context sheet, photograph and deposit or accession entry?
- What records show allocation, export or transfer after excavation?
- Were any files transferred, restricted, lost or separated from the objects?
- Which national law or institutional policy governs inspection and copying?
Limits of a general assessment
There is no universal checklist that proves participation in every country or period. Record-keeping duties, concession systems, dealer regulation, archive access and ownership rules differ by jurisdiction. Official guidance does not provide a topic-specific statistic for how often dealers participated in excavations or how often the relevant records survive. A case-specific conclusion requires the named dealer, object, excavation, country, dates and applicable law.
