Library publishing is a growing and vibrant field within academic and scholarly publishing. Academic libraries, and sometimes public libraries as well, publish a variety of print and digital publications; often these are focused on open access publications. Some, but not all, library publishing organizations are associated with or partner with a university press at their institutions. Professional development for this field has been a priority for the Library Publishing Coalition and for the Educopia Institute, leading to the development of the Library Publishing Curriculum project, generously funded by the Institute of Museum and Library Services. The first two modules have recently been released, on Content and Impact, and two additional modules will be released soon, on Policy and Sustainability.
