Record legal status and scholarly provenance separately
The framework blocks two shortcuts. The absence of a watermark does not establish the public domain. Conversely, lawful free reuse does not leave an academic image without provenance. Status and citation answer different questions.
Distinguish the Public Domain Mark, CC0 and term expiry
The Creative Commons Public Domain Mark labels works that the person applying it believes are free of known copyright restrictions worldwide. It does not itself change the work’s legal status. Creative Commons advises against using the mark for works that are public domain only in some jurisdictions. Identify who applied it and read the information attached to the item.
CC0 operates differently. A rights holder uses it to waive copyright and related rights as far as legally possible. Creative Commons notes that no tool can guarantee a complete waiver of every relevant right in every jurisdiction. Preserve the exact CC0 link and assess rights involving people, trademarks or embedded works separately.
Under section 64 of the German Copyright Act, copyright generally expires seventy years after the author’s death, with calculation and special cases governed elsewhere. That headline rule is not a licence to guess. Anonymous, joint, photographic or posthumous works can raise different issues. This page gives general information rather than case-specific legal advice.
Build a source record that leads back to the object
Start from an authoritative collection item page rather than a search-engine image. Capture the normalised creator name, work title, date, institution and inventory identifier. Link the individual object or file record. Include the rights statement shown there and an access date. Leave an unknown field as unknown rather than filling it from assumption.
A template is: “Fig. 5: [creator], [title], [date], [collection], accession no. [number], digitisation: [provider or photographer if stated], [item URL], marked Public Domain Mark 1.0, accessed [date]; cropped by the author.” For CC0 material, replace the status phrase with the linked CC0 statement.
Even where a legal tool does not require attribution, citation lets a reader locate the object, evaluate your selection and connect an interpretation to the correct version. Creative Commons recommends considering TASL information for public-domain material, including the original creator and hosting institution where reasonable.
The historic work and its digital file are not identical records
A public-domain painting may reach you through a modern photograph, scan or restored file. Identify the work and the specific reproduction. Section 68 of the German Copyright Act provides that reproductions of public-domain visual works do not receive the related-right protections described there. A delivered file can nevertheless involve metadata, contract terms, trademarks or other legal questions.
Do not put the platform in the creator field as though it made the historic work. “Digitisation supplied by …” preserves the roles. Where a photographer is named and the status of the reproduction is uncertain, resolve the information before use.
Museums and archives may offer several files for one object. Prefer the version with traceable provenance and stable identification rather than automatically choosing the largest download. The guide to museum and archive images expands this two-level analysis.
Describe three different status routes accurately
Public Domain Mark: “[Creator], [title], [year], [museum], accession no. […], [item URL], Public Domain Mark 1.0, accessed [date].” Confirm that the mark applies to the particular object or file rather than appearing only in a broad collection policy.
CC0: “[Creator or institution], [title or subject], [year], [dataset or item page], CC0 1.0, [CC0 link], accessed [date].” The credit preserves provenance even though CC0 does not make attribution a licence condition.
Your own term research: “[Creator], [title], [year], [original publication or collection], [digitisation], [URL], accessed [date]; work recorded as public domain in the German context after documented review.” Keep the term calculation in the working notes. International publication or uncertain authorship requires further scrutiny.
Seven checks before inserting the image
- Identify both the object page and the exact file.
- Take creator, death date and status only from supportable records.
- Do not confuse the Public Domain Mark with CC0.
- Consider the relevant jurisdiction and future publication locations.
- Separate the work, reproduction, institution and online location.
- Disclose your adaptation and review additional rights.
- Keep caption, figure list and bibliography consistent.
The media citations hub connects further visual-source workflows. The foundation guide to academic writing and evidence places provenance in broader source practice. If the file carries a CC licence rather than public-domain status, use the TASL attribution framework.
