Which institutional impressions are the right comparators for assessing wear in this one?

Every wear judgement is a comparison, and the comparison is only as good as the comparators. Building a short list of impressions that are securely catalogued by state, openly imaged at high resolution, and reusable under an open licence is a piece of work that helps anyone studying this plate, not only this project. It is the part of the census that is useful to scholars who have no interest in a privately held sheet.

The census has been opened and is being populated from institutional collection records. Coverage by state is currently uneven.

1. 01Populate the census from institutional collection records, recording each institution's own cataloguing verbatim.
2. 02Flag which records state a state, which expose an openly licensed image, and which expose a IIIF manifest that can be compared side by side.
3. 03Identify gaps by state and approach the institutions holding relevant impressions.

A census with at least one openly imaged, securely catalogued impression per state.

• Impression census

• RQ-02Which of the four New Hollstein states is this impression, and what distinguishes state III from state IV?
• RQ-09Does any drypoint burr survive in this impression, and what does the plate wear indicate?
