Mine too. I have quite a collection of books rejected by libraries. Mostly folk and music, but others of historical interest. My sets of Brown (North Carolina) and Randolph (Ozarks) and Peacock (Newfoundland) and Universal Songster are library discards.
The public are not interested in folk or older music or the past (Dana, etc.).
Of course novels by Marryat. Long live Snarleyyow!
