Penn subscribes to a number of dedicated citation indexes but you can also find that same functionality in other databases. Below are a few examples.
Web of Science: Provides access to the Social Sciences Citation Index, Science Citation Index, and Arts and Humanities Citation Index. Search for scholarly articles in any discipline, or for articles that cite a known author or work.
Google Scholar: Features citation information for many articles retrieved. Look for the "cited by" link in the brief record.
Periodical Index Online: An index to tables of contents of periodicals in the arts, humanities, and social sciences, including some published as far back as 1770. Includes periodicals in English, German, Italian, French, Spanish, and other Western languages. Provides access, where available, to page images in the related Periodicals Archive Online (PAO).
A research project can generate hundreds of citations from diverse sources. Learn about citation management software that can help you save and organize your citations, as well as automatically generate bibliographies. Penn Libraries supports the use of two tools: RefWorks and Zotero.
RefWorks - web-based tool for extracting citations from databases and creating bibliographies.
Zotero - free, open source tool for saving citations in your browser, from databases or web sources.
