Archive Finder is an index of over 206,000 manuscript collections as well as a directory of primary source repositories in the United States, United Kingdom, and Ireland. Researchers can use it to determine whether a collection contains material useful to their work. Archive Finder is comprised of ArchivesUSA and the cumulative index to the National Inventory of Documentary Sources in the UK and Ireland (NIDS UK/Ireland).
In support of the University's budget mitigation efforts, AU Library had to make cuts to our collection and cancel some resources. Unfortunately, access to Archive Finder ended June 30, 2025.
We recommend these resources as alternatives:
ArchiveGrid
The UK National Archives
US National Archives Catalog
The National Archives of Ireland
National Records of Scotland (NRS)
