The Quatrefoil Library is a dream-come-true for David Irwin, a gay bookworm. In the mid-1970s both he and Dick Hewetson started collecting thematically gay books. In 1977 they moved into a large condominium, combining collections in a linen closet. But as David continued to buy ever more books, the collection soon outgrew the "closet." When the two parted in 1984, their more than 1500 volumes remained united.
In November 2013, the library re-located to Minneapolis, in the ground floor of the Spirit on Lake building. This residence is one of the first to focus on housing for GLBT senior citizens.
