A friend of mine is putting one of these together for their house. A little weather resistant library to put at the end of ones drive.
Just a neat idea I’ve never heard of before with some opportunity for customization. Might be able to turn a tidy little profit every now and then 
Getting started: Build a Little Free Library - Little Free Library
Seems like they’re pretty flexible on who can make them and all that jazz. The only caveat they mention is that the owner needs to buy a “charter” for $50 which basically registers the library with the organization. (They’re pretty lax on what can be put on the charter sign too, so folks could credit the builder and whatnot 
)
