I just received an e-mail from PBS telling me a book ( paperback) which is "similiar" to one (a hardback)  on my WL was just posted, and giving me the opportunity to request it. It has been so long (many months? years?) since the last time this happened I thought this feature was never going to work again.

Nice to see this feature back. 

I haven't gotten one of those notifications in ages, and usually when I did, the book was already gone to someone who was faster than I was. LOL

I get those notifications all the time, never noticed a period where the function was not working.
