Universities, colleges, and other academic institutions are increasingly implementing and supporting institutional repositories (IRs). Typically, an institutional repository includes a variety of digital documents produced by scholars throughout the institution, including journal article e-prints, data sets, presentations, technical reports, and teaching materials. Institutional repositories can also include digital versions of graduate students' theses and dissertations (called ETDs). The Institutional Repository and ETD Bibliography 2011 presents over 600 English-language articles, books, technical reports, and other works that are useful in understanding institutional repositories and ETDs. This selective bibliography covers IR country and regional surveys, multiple-institution repositories, specific IRs, IR digital preservation issues, IR library issues, IR metadata strategies, institutional open access mandates and policies, IR R&D projects, IR research studies, IR open source software, and electronic theses and dissertations. Most sources have been published from 2000 through June 30, 2011; however, a limited number of key sources published prior to 2000 are also included. The bibliography includes links to freely available versions of included works, such as e-prints and open access articles.
