Hi all: I think sometimes these things happen, but there is a concern that books with the BC labels can be tossed out by a thrift shop--I know a lot of the British Charity Shops have similar policies and there have been warnings posted by British Bookcrossers about this going on over/across the pond, etc.
There is something of a mini-chain in the suburban Boston area, called Used Super Bookstore or similar name. They take bulk donations of books and sell them at a steep mark down scale, price lowered as the book resides there. But a fellow Boston Bookcrosser mentioned to me they learned they toss any books that say they are free/have any kind of free label. But I don't live anywhere near enough for a location to work out any kind of a plan with a manager, etc.
This past year, I had a bit of a melt down when my local, i.e. small town, public library had 6 dozen dumpsters/not recycle filled with books set out. I rescued about 4 grocery bags worth. Sort of really burnt my toast b/c they have an in-house thrift shop where they sell both books removed from circulations/donated to raises funds for books. There were a couple of first editions I found in my rescue cache I prompted donated them to other libraries and nonprofits. In this specific case, it's the new library director b/c my mom mentioned it to the assistant librarian who runs the mystery book group and he did the little I'm not in charge shuffle. I mentioned this incident to two (2) retired librarians at the Mass. JASNA mtg., not long after and they were appalled. I also posted on a librarian's blog that wrote about "weeding" and she too conceded this seemed poorly managed. I guess this new library director is more concerned with special events, recently a tea tasting that my aunt wanted us to go to and I told my aunt I would skip it b/c I still really cannot be civil to this woman. I ran into her one day trying to return my mother's mystery book club book and she pertly told the library was closed for the day/for some type of staff training. I thanked her and fled.
In closing, not Bookcrossing related, but this professor inadvertently bought her lost book back from Amazon. Apparently she'd lent it to a student--now keeps better track. Here is a link/url:http://nymag.com/---/professor-buys-personal-copy-of-book-she-lost-on-amazon.html
