The Portal to Texas History (http://texashistory.unt.edu) and the University of North Texas (UNT) Digital Library (http://digital.library.unt.edu) contain more than 445,000 items collectively, hosted by the UNT Libraries. These collections include a variety of serial publications such as newsletters, magazines, scholarly journals, annual reports, and yearbooks. Many of these serials are key resources for the user groups of both repositories. In this article, we discuss the importance of serials within our collections, some of the challenges, the standards we use, and how we leverage metadata to facilitate access to serials for diverse global users.
