Ask A LibrarianRepositories are created at institutions and by organizations to house, and make searchable, textbooks, courseware, and individual learning objects. See the list below for some of the many OER repositories that are out there. Because the number of individual repositories is growing, some tools to search multiple repositories simultaneously have been developed. See the search engines/aggregators box to the right to try some of these.
