RLI 281 US and Canadian Disability Policies, ReEcent ChHallengesENGES, and US and Canadian CopOPyright Law 18 DECEMBER 2012 RESEARCH LIBRARY ISSUES: A QUARTERLY REPORT FROM ARL, CNI, AND SPARC As a result, carefully and deliberately negotiating these licenses is critical to making materials accessible. Terms limiting libraries’ ability to copy and modify content may foreclose the ability to make accessible versions of library materials, compounding the issues described above. By the same token, however, more favorable terms may give libraries broader rights to adapt content to meet the needs of patrons. Libraries can require that any licensed content come with accessibility “baked in” (see Appendix A). Individual libraries and consortia must carefully strike this balance, as they have always done when acquiring content.
