Seminal works are key works in a field: articles, books, or other texts that are introduce new knowledge in a particular field. You'll see them cited over and over again as you go about your literature review.

Northcentral University has compiled a guide to finding seminal works, together with a workshop on finding seminal research that can be viewed online.

Two additional key resources are Scopus and Web of Science, two interdisciplinary databases that allow for sorting of results by the number of citations of a particular article.


Scopus
Scopus is the largest abstract and citation database, including peer-reviewed titles from international publishers, Open Access journals, conference proceedings, trade publications, quality web sources. Subject coverage : Chemistry, Physics, Mathematics and Engineering ; Life and Health Sciences ; Social Sciences, Psychology and Economics ; Biological, Agricultural and Environmental Sciences.
 
Once you perform your search, you will see a drop-down menu at the right of the screen that allows for sorting by a number of different options, including "cited by." Selecting this option will rank you results in order of the number of times each has been cited.
 
 

Web of Science


Web of Science offers multidisciplinary coverage of over 10,000 journals in the sciences, social sciences, and arts and humanities, as well as published proceedings for over 12,000 conferences per year, and over 50,000 scholarly books. Powerful tools allow you to search and see what articles in the database have cited a particular work, as well as perform other analytics.

In addition to sorting by times cited, this database offers tools for analyzing search results and creating citation reports.
