I first saw bee hives at Salt Lake City where they were/are on the roof top of the library, but visible inside.
I have also seen them at Anythink Perl Mack as part of the community garden,
Anythink Wright Farms, also as part of the community garden
and Robbins Library, on a closed balcony.
They also had a display downstairs, about the bees, and the partnership with the local bee keepers.
Cornell Library has digitised some important work about bees.
There are probably many more libraries with bees. I really like this development, as it has an educative and environmental approach. It would be lovely to see more libraries with bees.
