The wide application of digital technologies in the library environment has changed the format and content of subject guides. Given the advent of new Internet tools and the explosive growth of electronic resources available on the Web, the reference librarians at the University of Maryland (UM) College Park were facing many issues when keeping up with new technologies and creating subject guides that meet library users’ satisfaction. The goal of this paper was to explore the challenges librarians are facing and to identify new technologies to assist them in creating subject guides. The literature revealed a wide variety of librarians’ attitudes and practices in creating subject guides at various university libraries nationwide. A survey was conducted with UM librarians and subject guide users to determine user expectations of the UM subject guides. This paper will provide subject librarians with useful tools for creating subject guides in the electronic environment.
