A citation trail is one way to describe a search that:

• Examines the bibliography, references or works cited section of a specific article to identify relevant sources published previously. This is sometimes called Backwards Searching.
• Identifies any sources that have cited or referenced a specific article since that article's publication. This is sometimes called Forwards Searching. 

Within LibrarySearch, you can follow a source's citation trail by taking the following steps. 

Step 1. Open the more detailed article record by clicking on the title.

Step 2. Select "Citations" from the menu on the left.

Step 3. Click "Citing This" to find relevant sources published previously or "Cited in This" for relevant sources published since. In the following image the number 1 indicates the location of the "Citing This" feature and the number 2 highlights the "Cited in this" feature. 

One trail leads to sources that cite the work. The other trail lists the references cited in the work.

Citation trial tools may not include all citations to or from a given work. Find out more about Citation Trails.
