The Friends of the Library chapters are true believers in the library system and the importance of reading. Every time I attend a Friends of the Library book sale, I wish I were a member so I could have access to all of those donated books before they go on the shelves.
I once bought a huge collection of nostalgia-based magazines for just 4 dollars and then donated them to a local nursing home. The residents really enjoyed them, because the issues always feature articles and picture from the "good old days".
I never would have found them if a Friends of the Library volunteer hadn't told me about them after they had been donated.
