I am one of those foreign members who is very glad to have access to the library as there is no local ebook llibrary services around.
I can't see what the problem is with finding a book to borrow as there are around 20000 fiction titles and only a few thousand are out at one time. I suspect that is the most recent ones. Surely there is something in the remaining 17000 that people would be interested in.
I did see the latest Lee Child book with 18 people on the waiting list. If you really want to read that just buy it or read something else
I noticed that they have now increased the borrowing limit to 12 items.
Gees, I read a book a week so it seems a little wasteful and just encourages people to checkout books they are not going to have time to read unless you are a pretty good speed reader
