Developed by Elsevier, CiteAlert is a free, "keep me posted-type" email service. Once an author is registered, the author will receive an email alert when the author's article is cited by another author in a newly published article. What the catch? 1. The newly published article must be an Elsevier journal. 2. The author's original article must be indexed in Elsevier's Scopus databae, and published since 2005. 3. No self citations.
