Here’s a lesson for book collectors: Sometimes, even in popular and well-documented fields of collection, something slips through the cracks. In this case it was a 24 volume set of the collected works of Abraham Lincoln, missed by all previous Lincoln bibliographies, the last volume of which is bound holographic letters by Lincoln and others. So how could all the previous Lincoln bibliographies have missed it?
Perhaps because the entire print run of this edition was limited to 8 copies.
