In my travels, I’ve seen several different ways of returning materials to libraries (drive-thru overhangs, boxes on the street, self-serve RFID chutes), but this method at a library in the Florida Keys is one I hadn’t seen before.
According to staff members at the Helen Wadley Branch Library on Islamorada Key, it’s not uncommon for patrons to pull up in their boats in the waterway behind the library to drop off their books. And lo and behold, a sailboat did just that when I was there!
Another interesting tidbit about this library: the building was originally built as a storm shelter and school after the hurricane of 1935 and funded by the Works Progress Administration (four bas-reliefs created by WPA artists still hang on the walls). It became a library in 1966.
