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.
