The staff maintains a lost and found for electronics, backpacks and other items they can't identify for return. Bring identification for electronics and call ahead to see if they can at least tell you if they have the type of item you lost. Good luck. Staff are great.
I believe the librarians will hold onto lost items. I'm not sure how long. I have gone back for misplaced items later that day and the next day and the items have been there.
