To amend the Museum and Library Services Act to authorize grants to support the use of public libraries for community economic development.

Public Library Innovation Space Act This bill requires the National Museum and Library Services Board to carry out a program for making competitive grants to eligible partnerships (composed of a public library and an economic development corporation, a local government, a state government, an elementary or secondary school, a museum, an institution of higher education, a nonprofit organization, a corporation, and/or other entities identified by the Board) to establish makerspaces at public libraries. A makerspace is a facility (which may be at a fixed location or a mobile unit) that is open to the public and provides individuals with access to: (1) tools, technology, and educational resources designed to enable such individuals to create physical goods, including prototypes; and (2) educational opportunities, including vocational training and assistance with early-stage business ventures. A partnership must contribute, for the activities for which the grant was awarded, nonfederal matching funds equal to the grant amount. Each eligible partnership that receives a grant may not use its grant funds, or the matching funds contributed by it, for construction activities at a public library that would provide extra square footage to house a makerspace.
