In the university, there I've studied there was a place, there you could leave smaller things, which everyone could pick off for free. This could be a t-shirt or mp3-player or a pc-game or whatever...

So I think it would be better to have a general tag for such a place (leave something, which you don't need any more and someone else can pick off this). If there is a limitation (eg. only books) this could be tagged additionally.

    If you cannot develop a list of tradeoff values then keep
    amenity=public_bookcase.



+1, also if they don't have something more in common I'd go this way. The other place you wrote about of that allows to bring and pick-up different stuff could maybe also be a kind of shop? Generally it doesn't seem useful to look for all kind of tradeoffs (e.g. if you are looking for books you won't be interested in other kind of tradeoffs, and these public book shelves are quite a particular implementation very specialized for books, e.g. if there was a tradeoff for bicycles they would not have a lot in common with the book ones.

cheers,
Martin
