Top 100 O.P. Titles
Book Finder has released a list of the top 100 out-of-print titles.
At #1 is a title that will bring back memories for those who were working in libraries in the early ’90’s — Madonna’s Sex. If you still own copies (WorldCat shows 179 libraries own the original Warner Books edition), you may want to safe guard them so they don’t walk.
The list shows a wide range. At #4 is the Harvard Classics. and at #5, On the Nature and Existence of God, by Richard M. Gale.
