"Pearl Growing" and Citation Mining

"A powerful strategy good researchers use to find information for their literature reviews is known as 'pearl growing' or citation mining.

Based on the idea that sand forms grain by grain into a pearl, so a literature review develops citation by citation.

Pearl growing/citation mining is a process of looking for information that can work backwards or forwards:

  • Backwards: You can discover new information resources for your review by looking at the bibliography of a book or an article and seeing which resources an author consulted to do their research. Subsequently, you can then check those resources and perhaps incorporate them into your literature review.
  • Forwards: You can discover new information resources by determining who cited the book or article you're currently looking at. Then you can look for those sources that cited your first source and incorporate them into your review."
