There are some important databases and resources for discovery of archival materials held in the US and Canada. International archival collections are connected on many levels; for example, a US library that holds part of a person’s correspondence is a starting place for finding other parts of the correspondence abroad.
Finding Aid Portals for European Libraries
The union catalogs for books, along with the national bibliographies (including retrospective national bibliographies and digital libraries), can be used to find rare books, printed primary sources, and high-level records for archival materials. Portals or catalogs that allow a search across Finding Aids from participating libraries are a separate set of resources. The annotated listings below visualize the differences between regional directories (that list, say, each of the 3,600 archives in Germany) and portals that allow you to research catalogs and Finding Aids across regional or thematic collections. National libraries can be found at The Conference of European National Librarians (CENL), and national archives are included in the Archives Portal Europe.
The Archives Portal Europe has built a list of useful links, including links to some very evocative subject collections. The following are a few examples of online portals identified and described on the Archives Portal Europe page.
Digital Content
A great first stop for finding digital content is the KIT Karlsruhe Virtual Catalog (KVK), which offers a cross search covering important digital libraries, including:
The following is a selection of public domain digital libraries of reproduced primary and archival sources (some connected to national libraries, others not) that illustrates the variety of free content offered online.
A specialized discovery tool for digitized collections is the Datenbankinfosystem DBIS (Databasefinder), which offers 13,000 resources with annotation, and both free and subscription access. Most recently funded by the Deutsche Forschungsgemeinschaft (DFG; German Research Foundation), it serves as a local database finder in over 300 German libraries. DBIS is only available in German, but the interface can be searched for freely available content even with very limited knowledge of the language. For example, once a French open resource has been identified, the user can click into the French resource and read, in French, the description in the “About” section, and does not have to rely on the German annotation. The following describes a path to free access to UK databases:
