QUESTION: Standardized Chapel Library Project
Submitted by lyndyn on Fri, 09/21/2007 - 5:26pm.question / pregunta:
Are the libraries of private, for-profit prisons subject to the Federal Bureau of Prisons' Standardized Chapel Library Project policy? The librarian to whom I supply materials via ILL is claiming compliance with this policy as a reason to limit inmates' access to religious and scholarly material, but I think it's only enforceable within the federal prison system.
