I assign the Helsinki metropolitan area library service.
I have had the French
Fellowship of the Ring loaned since September or October and this far, I've renewed the loan five times, which is the maximum. So on Monday, I went to a library, rather sad, for I hadn't managed to finish the book and I had to return it. Besides, I had just picked it up again and I had the feeling I would finish it soon if I could just keep it for a week or two. I went to the desk and paid some old debts *mumbles something about returning books a bit late*. Then I asked the librarian about the
FotR. She said I can't renew the loan anymore, because the book has to return to the library after five renewals. However, as I had the book with me (as I had intended to return it), she just looked that it was ok, apparently made some marking on the library database and I was allowed to loan the book again right then.
I love flexible systems and user-friendly service, especially as they are quite rare these days.
