Publishing services provided by libraries are expanding and professionalizing, suggests a new report released for comment today by SPARC, the Scholarly Publishing and Academic Resources Coalition, on behalf of a team of researchers from the libraries of Purdue University, Georgia Institute of Technology, and the University of Utah. The report is the result of a year-long study of library publishing services made possible by a collaborative planning grant from the federal Institute of Museum and Library Services (IMLS), with additional support from Berkeley Electronic Press and Microsoft Research.
