Set up a free account at Web of Knowledge to be notified when articles are cited. This can alert you to potential collaborators who are working on similar topics, assist you with locating articles on similar topics, and help you know how widely your work is being disseminated.
The Web of Knowledge database (containing Science Citation Index and more) is interdisciplinary and includes citations to materials in the health and life sciences, physical sciences, social sciences, and humanities. Personalized accounts are free. Create one, and sign in on subsequent visits, by clicking the button at the top of any page inside the Web of Knowledge database.
You can set up citation alerts to send you an email or subscribe to an RSS feed. To set up an alert, search Web of Knowledge for the paper you wish to use as the subject of the alert. Click on the title of the paper to view the full record (see screenshot below of a full record).
Click on the button on the right-hand side of the page to set up an alert, which will be active for one year from the date of creation. You will receive an email whenever your article is cited by another article in the Web of Knowledge database.
To view all your alerts, subscribe to an RSS feed for a citation alert, or renew an alert for another year, click the link at the top of any page inside the Web of Knowledge database.
