New York City records planning: start with custody and a usable identifier

Start with the public record you are trying to find

New York City research begins by separating historical archives from an agency-held record. The Municipal Archives preserves City-government material in many formats, including paper, digital collections, maps, blueprints, ledgers, sound recordings, and vital records. For pre-consolidation local-government history, its Old Town records guide is a useful example: Collection MSS0004 — RG 096 covers former municipalities now within the five boroughs.

Use the guide’s collection identifier, the creating office, a borough or locality, record type, and an inclusive date range in a research note. The Old Town guide says digitized or microfilm copies should be used when available, while original material may require arranged onsite access. That makes it a research pathway, not a promise that every item is online or ready for reproduction.

Choose a public retrieval route before a production project

For an existing City-agency record, OpenRECORDS is the City platform for Freedom of Information Law requests. State the agency likely to hold the record, its subject, date range, known file or collection reference, and whether inspection or a copy is sought. A focused request helps the custodian locate an existing record; it does not ask the agency to create a new index, answer research questions, or authorize a scan of archival holdings.

If a government, library, or engineering organization already owns or controls a collection, its digitization planning is a separate task. Confirm custody and internal authorization before inventorying material for imaging. A public retrieval request is for access to a government-held record; it is not a transfer of the record to a commercial scanning project.

Give a controlled collection its own identifier

A concise internal ID makes a multi-reel or mixed-format inventory easier to discuss without borrowing an archive’s call number. For example, NYC-ENG-024 could identify an engineering department’s project-file microfilm group; the accompanying record should name the creator, series, borough, date span, reel or fiche control number, format, and any index already present.

Keep the ID stable through inspection, sample review, image naming, and later import planning. Add a note that distinguishes the organization’s identifier from a public research reference such as MSS0004 — RG 096. The two identifiers answer different questions: one locates a source in the Archives, while the other controls the collection your organization is permitted to manage.

Check access, retention, privacy, and rights before release

DORIS explains that City retention and disposition schedules underpin the retaining, preserving, transferring, or disposing of City records. For a collection you control, identify the responsible records officer and confirm the applicable schedule, any hold, access restriction, personally identifying information, copyright or license terms, and approved audience before copying or publishing files.

This is practical planning information, not legal advice. Do not use this guide to authorize a retention decision, public release, or destruction. The responsible public agency or organization should decide those matters under its governing rules and counsel where appropriate.

Use the guide as a readiness check

A government, engineering, library, or archive team can leave this page with a sharper next step: either begin public research with a collection or agency reference, or document the collection it controls. For the latter, capture format counts, condition observations, a sample of existing labels, required lookup fields, and the intended access use before considering conversion.
