I rarely miss a book I’ve donated. I must just have good judgment for my purges! Once in a great while I go looking for something I gave away ... but if it turns out to be important, I can check it out from the library.
I got Richard Burton’s “The Tents of Midian” from Dover with my last order of coloring books. We needed something to bring the total up to ... whatever ... for the free shipping. I’m having fun with “Arabesque Floral Patterns” and “Art Nouveau Animal Designs.”
We didn't purge it, we just misplaced it.
