PubMed and Sorted by Computed Author

Because the format for searching for author in the PubMed database is last name first and middle initials (for example, to search for articles by Alexander M. Walker, you would search for walker am), it may be difficult to distinguish whether the citations in your result list were actually written by Alexander M. Walker or by someone else with the same last name and initials.  Well, PubMed recently introduced a handy feature to help with this - Sorted by Computed Author.  After you run your initial author search and locate a citation that you know was written by the author that you are interested in, you then display the citation in the Abstract format and click on the author name link.  Your results will then be displayed in Sorted by Computed Author order.  PubMed has compared citations with the same author name and then used metadata for each citation such as affiliation, abstract, MeSH terms, journal, title, grants, and publication dates, clustering together citations that are highly similar to each other and classifying them as belonging to the same author.  These citations are then displayed in order of similarity, with the more similar closer to the top.
