I really admire what you do and I'm always happy t read your posts to see what treasures you have found. My brother is a postcard collector and has been in a similar situation. His long term supplier (also a collector) has vanishes, to find out later that he has passed away. Luckily his kids took over and sold the rest of the stuff.
I took a bunch of books to the library at the beginning of the month as I knew it's the right place. I know how much time I had to spend on finding the right books when I was in Uni, at least I can help others with my donation. The library lady was thrilled to accept them.
Keep up the good work my friend, recycling is always good.
Great job! There are thousands of books outside all the time here. I can't take them, but I do grab a few that stand out. Donating them is brilliant when compared to the wasted books I see here. I simply can't carry them when it's late at night. If I find them by a thrift store, I'd bring them in, but they're closed when I'm outside.
