Citation databases can be used for cited reference searches, enabling you to find, check and track citation data year-by-year, navigating forward and backward through the literature related to a topic.
There are two ways you can use citations to find additional resources:
Backward. You look at an information source's citation list - this will lead you to material that is older
Forward. You look at who has cited that information source - this will lead you to material that is newer
Following citations backward
This method helps you find information that is older. Keep this in mind if your lecturer would like you to use recent material.
Following citations forward
Some, but not all, databases have a feature that allows you to see who has cited the article you're looking at.
The database may not show you every citing article, so you may need to look in more than one database.
