CiteSeer has been around since 1997, when it was first created at the NEC Research Institute at Princeton University. It was the first digital library and search engine to provide automated citation indexing and citation linking using the method of autonomous citation indexing. The library is primarily focused on the literature in computer and information science, and the project partners include Pennsylvania State University, the University of Arkansas, and King Saud University. First-time visitors can check in on the site by using the "Most Cited" area to learn about commonly consulted documents, authors, and citations. Moving on, visitors can also perform their own searches by using the embedded engine on the homepage. Also, visitors are encouraged to log-in to create their own profile so that they can save searches of importance.
