Welcome to the collections of the Allard Pierson

About this site

This website provides access to finding aids of collections and archives held within the Allard Pierson. A finding aid is a tool that facilitates the discovery of information within a collection or archive of records. It describes what is in a collection or archive and provides context by giving you information about its provenance, acquisition and history. Some finding aids on this website also contain a hierarchical structure with item-level descriptions. The level of detail can vary between the finding aids.

Requesting Materials

To request materials, please select the Request button at the top of the finding aid page and follow the instructions to make a request. The materials are only available for examination and must be used within the library. Access to the materials may be (temporarily) restricted, for example when conservation work or digitization is taking place. Access restrictions are noted in the finding aid. Some collections and archives have not yet been processed, and therefore an online finding aid is not currently available. Please contact us if you want to use unprocessed materials or if you are unable to find a finding aid, but have reason to think we may hold the materials you are looking for.

If you would like to consult archival materials, it is necessary to have a visitor pass or a university library card.
