Sharing the blame with publishers and editors for insufficient diversity are U.S. libraries, a natural market for books by and about minorities. Why aren't they working more closely with publishers to close the diversity gap in every way? Yes, the American Library Association's president elect is an African-American; so is Carla Hayden, CEO of Baltimore's Enoch Pratt Free Library. Of 118,666 credentialed librarians, however, just 6,160 were black and 3,661 were Latinos in 2009-2010, as tallied by the federal government and mentioned in an ALA diversity report. With even fewer minority males — to serve as role models in libraries — black and Latino boys suffer.
