Diggins, who spent his childhood in Harvard, provided a generous bequest to the City of Harvard for the purpose of building a library. That building, named the Delos F. Diggins Library, became the first free-standing public library in McHenry County. The library served the community successfully from that building until a new library was built in 2001. In deference to the lasting legacy of Delos Diggins, the library was renamed the Harvard Diggins Library.
