Libraries Can Provide Enhanced Access to OA Works Providing access to open access materials has inherent challenges similar to those of other freely available digital works on the Internet. Schmidt et al. identify a number of these challenges: the effort required to effectively select and catalog (or otherwise create metadata for) high-quality OA materials from a pool of candidates that is not restricted by materials cost considerations; difficulties in tracking changes in dynamic OA materials and monitoring their availability when the library has no special relationship with the publisher or other supplier; lack of adequate coverage of OA materials in indexes, aggregator databases, and other conventional finding tools; the necessity of using search engines and specialized finding tools to identify relevant materials; and the broadened scope of information literacy programs to account for the peculiarities of these materials.
