Library of Congress Subject HeadingsLarge call number ranges are devoted to topics related to Christianity, including all of the books with call numbers starting BR (on Christianity) and BX (on Christian denominations). In addition, the BS range covers the Bible while the BTs and BVs are on doctrinal and practical theology, respectively. And, of course, you can books relevant to research of Christians and Christianity with almost any other call number too. The subject heading Christianity might be a useful starting point, but would require narrowing. These subject headings are just a few that might be more useful for research on Christianity.

The tabs below represent three call numbers (BR, BS, and BX) with material particularly relevant to research on Christianity. E-books do not have call numbers and consequently have their own tab.
The primary sources below are arranged according to broad chronological categories (early Christianity, medieval Christianity, Reformation-era Christianity, and modern Christianity). Of course, this is just a small sample of material that is out there. Check the History Research Guide or contact me for help finding other sources.
