Did you know you can record a reusable search strategy in PubMed, the Internet version of Medline from the National Library of Medicine? You can then rerun the search periodically to keep track of new publications on your topic.
PubMed includes not only Medline but also PreMedline, article citations that are in the process of being indexed for Medline. These records are very current, but can only be searched by text word as they lack the Medline subject headings and descriptive tags. Ovid Online, a new version of Ovid coming to JEFFLINE early this summer, will include PreMedline as a separate database.
Begin to record a PubMed current awareness search by entering your search terms. PubMed will automatically map your search terms to both MeSH medical subject headings and text words. Most searches can be typed directly into the main search form.
Note that the current awareness feature will not work with strategies that use set numbers. Multiple sets can be converted to a single complex search strategy using the Preview/Index feature.

To see if the software has interpreted your search strategy correctly, choose the Details link. If you are satisfied with the strategy, choose the URL link.

Bookmark the resulting page on your web browser. You can rename the bookmark by editing the entry in your browser's Favorites or Bookmark file. Make a note of the date when you recorded the search.
To run the current awareness search, open the bookmark. Choose the Limits link.
|
|
Choose either the limit for publication date or Entrez date [the date the citation was entered in PubMed]. Enter the date that you last viewed search results and the current date, then choose Go.
|
Note that the record date will not change when the item is added to Medline, so if a PreMedline article is indexed with one of your subject headings but did not have any of your text words, you will not see the citation in your search results. To be thorough, you can include many text words or exclude PreMedline entries from your search by choosing the Medline subset under Limits.
