Compiling a booklist using LibraryThing was a lot easier than searching an average online catalog. Even if I couldn't remember the exact title of a book, LibraryThing would pull it in for me from an approximation.
I chose the Amazon database instead of Library of Congress and obtained wonderful pictures of book covers along with titles. The list, however, was quickly becoming monstrous, so I limited my choices to 24 titles. I could have picked so many more. There is just so much on Lincoln worth reading.
So check out Bookzilla and Son of Bookzilla in the righthand column, just under the weblinks. Bookzilla will connect you with the complete display of my list on LibraryThing. Son of Bookzilla provides a random feed of 5 titles from that list to my blogsite.
LibraryThing is very user-friendly and provides not only the book you're looking for, but similar titles you may not have read. It's a great way to expand your future reading list.
Also, don't forget to check out "Reading the Man," a newly published collection of Robert E. Lee's letters, as well as Kwesi Mfume's book on the Emancipation Proclamation (not yet released).
