Main search portals
-
Yale Library Catalog (Orbis)Searches the books, e-books, journals, government documents, and other physical and digital items owned by the library. Individual journal articles are not retrieved by the search. Can be used to find both primary and secondary sources.
-
QuicksearchA combined search of the library's books, journal articles, databases, and more. Searches Orbis as well as Morris, which is the Law Library catalog. Consider this a Google-like search of a vast amount of resources, but keep in mind some library materials are not indexed by the search. The search refinements and availability of multiple search fields are key to limiting the usually large number of results and finding the most relevant sources.
-
Archives at YaleThe search portal for finding archival materials at Yale. Look for the Scope & Contents notes, inventories, and PDF Finding Aids to assess the relevance of materials to your research project.
-

Hathi Trust Emergency Temporary Access Service
Hathi Trust’s Emergency Temporary Access Service (ETAS) provides online access to in-copyright books in the Yale Library collection. Catalog records for ETAS items can be found through Quicksearch and Orbis. If you’re already using the Yale VPN, you can click on the “Log In” link at the top of any Hathi Trust page and select Yale from the drop-down menu (if you access Hathi Trust without using the VPN, you will initially receive a prompt to use Duo Multi-Factor Authentication in order to access the database first).
A short video on the Hathi Trust ETAS can be found here, and a library guide here.
Scan and Deliver & Interlibrary Loan
The library now offers limited Scan & Deliver service. However, turnaround time for these services may be significantly delayed, and the fulfillment of Interlibrary Loan scan requests is dependent on our partner libraries. We ask that you prioritize requesting items that are the most urgent for your research. At this time, BorrowDirect and physical interlibrary loan services are suspended until further notice.
