Libraries all across the country suffer from being underfunded. Your library probably charges a nominal fee for interlibrary loan. They have to pay for the transport of the books. I would guess the fee would be under a dollar. Our ILL is free, which is great since we are in a very economically depressed area. I am prejudiced, but librarians are great people! You should ask for knitting books to be added to the collection, since it's so "hot" right now. Before you drop off knitting book donations, ask them if they will put it in the collection, otherwise your book could end up on the book sale. They evaluate the age and condition of items, and people drop off huge boxes of books every week. Librarians are always looking up!
