SciCentral will appeal to a wide variety of users interested or working in science or medicine. The site is first and foremost a gateway to thousands of online resources, grouped by science area (Biological, Health, Engineering, Physical & Chemical, etc.) and then subdivided by resource type (directories, specialized resources, databases, special reports, articles). SciCentral also features a number of diverse Special Features, including Academic Programs, K-12 Science, The Media Room, and a Bulletin Board, among others. Other resources include an internal search engine as well as links to science news wire search engines and science journal metasites. The site is quite large, and some users may feel overwhelmed at first, an impression not helped by the site's inclusion of several tangentially related resources. However, SciCentral's real appeal is what sets it apart from other science metasites: its strength as a current awareness resource, with links to current research highlights, breaking science news, and new articles from an impressive range of sources. In addition, the site has recently introduced a free customizable weekly science e-mail update service, which allows users to select from over 120 topics.
