Andrew Carnegie peppered the city with neighborhood libraries designed by his favorite architects, Alden & Harlow. They’re all little gems. This one has been abandoned for years, since a new library was built in the mostly empty business district of Hazelwood on Second Avenue. (That block of Second Avenue now seems to be the center of the Hazelwood neighborhood revival.) It is still in good shape, and—unlike an abandoned church or synagogue—it would be a relatively easy building to adapt to new uses.
