The majority of the collection is located in the closed stacks of the University Library. Requests can be made through the Leiden Catalogue. Works can also be shipped to the Van Steenis Building and returned there.

A smaller part of the collection can be found in the open stacks. The most relevant journals (and their back issues) are accessible in the basement (cabinets 14109-14128, alphabetical order). These volume can be loaned through the Circulation Desk.

Reading Room 3 (first floor) contains – under classification CC –the archaeological reference collection, with literature primarily devoted to methods & techniques and handbooks. This material is for library use only and can’t be borrowed. The current volumes of archaeological journals are to be found in the circular cabinets located near the entrance to Reading Room 2.

EDNA is the E-Depot for Dutch Archaeology. EDNA archives digital research data of Dutch archaeologists, such as GIS data, field drawings, data tables and photographs. EDNA was established by DANS (Data Archiving and Networking Services) and the Cultural Heritage Agency (RCE). Data can be searched by archaeological organization or by specific project (for example the Betuweroute and Maaswerken), and are accessible for other scientists. More than 80% of the archaeological data in EASY is publicly accessible.

To be able to make use of the datasets registration with DANS EASY is required, along with the permission of the depositor.
