A joint project of the American Council of Learned Societies and the Library of Congress, the collection consists of reproductions of nearly five million pages of manuscripts and, in a few instances, rare printed materials found in some of the major public and private collections of England and Wales. American scholars in many fields of knowledge selected the works for their intrinsic importance to learned studies. The collection spans several centuries; it includes many types of works (letters, treaties, public records, grants, papal indulgences, speeches, stories, poems, pedigrees, deeds, tracts, court cases, treasurer's accounts, journals, petitions, homilies, and commentaries), and covers a wide range of subjects (politics, religion, philosophy, literature, science, history), in many languages (English, Latin, Greek, Arabic, Welsh, French, etc.). This collection contains many important collections from the British Museum as well as the Public Record Office. CRL holds limited reels of this collection, some of which are cataloged under separate headings. The following is a short checklist of items, with the listing of the depository, LC Reel number, and corresponding BMP item numbers (these are in numerical sequence and may not match the order of LC Reel numbers). Titles can be checked through the checklist or via the online version at the University of Michigan.
