CCEL book bibliography
We maintain a database of books we have, books wanted, priorities, book statuses, etc. It's really mainly for internal use but I've made the page available for other interested people. The URL is http://www.ccel.org/bibliography. (It's also linked in the left sidebar of the "About the CCEL" page.)
We are able to give individuals permission to edit the bibliography. If you feel called to helping develop this list of books we want to add to the CCEL, helping locate copies on-line, etc., please contact me.
