Places devoted for general reuse of things are uncommon where I live in the U.S., so I do not know if there is a consensus term for them. I have seen "reuse and recycle facility" or "reuse and recycle center" used a number of times. These places accept things and materials and separate them into items purposed for reuse and those for recycling. The term "reuse shelf" is sometimes used for the area at these facilities that the public may go to to get reuse items for free. Since the area may or may not have shelves, I assume "reuse shelf" must have some general meaning to be paired with such areas. Items may be one or more of books, household items, sports equipment, paint, building materials or other items depending on the facility.
Places for just reuse are very scarce, as most people would bring such items to a donation center such as Good Will where reusable items are resold or use Craig's List. For books specifically, the term "free library" has been used as can be seen in this news article: http://www.denverpost.com/ci_23135032/tiny-libraries-front-yards-across-colorado-inspire-love. The article has references to the "Little Free Library" movement which has over 5000 locations mapped (using google maps and a registration fee to be mapped). "Little Free Library" is a registered trademark so can not be used. Although used in this and other news articles I've seen, I think "free library" is easily misunderstood and the intention may be lending rather than swapping or reuse. It may be useful to differentiate between a policy of lending, swapping, or "free to take" by such places. As for the term used in OSM, reuse seems to be understood whereas I don't think tradeoff would be. If one must specifically leave something to get something, "swap" is commonly used in the U.S. +1 for the idea of leveraging the existing OSM recycle tagging -- perhaps by reuse :-) . Murry
