Library of Congress: DRM a serious obstacle to archiving

Library of Congress: DRM a serious obstacle to archiving: But copyright law also hampers important work being done at places like the Library of Congress, and a major new report on the issue from the Library points out the problems with the current rules. One big issue is the exemption for published works in a library's collection; these can also be copied three times, but only to "replace a work in their collections that is damaged, deteriorating, lost or stolen or whose format has become obsolete." In other words, librarians can't backup or archive such works until destruction is well under way.
