An increasing number of academic libraries and consortia are launching digital publishing programs which utilize library resources, staff expertise, and openly licensed tools and platforms to produce, publish, and preserve the full range of scholarly outputs, from individual presentations and articles to monographs and journals.
The Library Publishing Coalition defines library publishing as the set of activities led by academic and research libraries and library consortia to support the creation, dissemination, and curation of scholarly, creative, and/or educational works.
Generally, library publishing requires a production process, presents original work not previously made available, and applies a level of certification to the content published, whether through peer review or extension of the institutional brand.
Based on core library values, and building on the traditional skills of librarians, it is distinguished from other publishing fields by a preference for Open Access dissemination as well as a willingness to embrace informal and experimental forms of scholarly communication and to challenge the status quo.
