Nothing good comes easy. And even if that good thing is easy, it probably requires a permit. Like, for instance, Little Free Libraries.

Last week, we wrote about how book-lending cottages have spurred some controversy. In some U.S. cities, community members have asked city governments to crack down on these obviously dangerous public torments — requesting their removal, or that owners first obtain permits so that no city codes are violated.

The occasional legitimate safety concern aside, we’re fans of the little guys. So we asked readers to tweet or Instagram pictures of their local book-lending boxes with the hashtag #MyLittleFreeLibrary in solidarity.

Here they are, Little Free Libraries across the globe — from Indiana to Indonesia — in all their menacing, educational beauty.

Libraries made out of old bicycle parts, painted with Hufflepuff house colors, crafted with stained glass doors, and painted with flying books? Knowledge may be dangerous — but it sure can be cute.
