Digital Library at Penn State using CiteSeerX

"Digital library developed by Penn State researchers hits 1 million articles mark  10 Jun 2009

Pennsylvania State University (Penn State) has announced that a new digital library and search engine created by its researchers now holds more than 1 million journal articles and other scholarly works that can be easily accessed by anyone.

CiteSeerX (, based in Penn State’s College of Information Sciences and Technology (IST), is designed to enhance the dissemination of scientific literature by making papers and other documents easier to locate online. The library provides resources such as algorithms, data, metadata, services, techniques and software that are transferable to other digital libraries – supplying users with more than just an index of search results. The newest version, released in early 2009, added the capability to search tables.

The search engine was developed by C. Lee Giles, David Reese professor of information sciences and technology and Isaac G. Councill, a Penn State Ph.D. recipient. It is based on open source software, which means it can be adapted as needed, by anyone, to fit users’ requirements.

The search engine also includes a feature called MyCiteSeerX, a customisable personal space where the individual user can do tagging, make corrections, create his or her own collections and monitor paper updates.

Other tools currently being developed include Our CiteSeerX, an environment where collaborating teams can work and share information within the library, and a feature that will allow users to receive alerts about new papers of personal interest.

CiteSeerX was funded by the National Science Foundation, Microsoft, NASA and the College of IST.
