Do you know how to use MeSH (medical subject headings) within PubMed to create a more focused result list?
1. Connect to http://www.pubmed.gov
2. There should be a dropdown menu labeled Search: PubMed near the top of the screen.
3. Click the dropdown menu. Instead of PubMed, choose MeSH.
4. In the search box, put in the first medical subject term you are searching for, such as rheumatoid arthritis.
5. Hit enter or click Search.
6. On the next screen you should see a list of possible choices. For example, the first choice is Arthritis, Rheumatoid. Put a checkmark by the result you are interested in.
7. On the right side of the screen, click add to search builder.
8. Now, to help you get a more focused search you should probably add in a second term before you search (usually). For example, in the long search box at the top of the screen, type in drug therapy. Click search (or sometimes it will give you a list of options while you are typing which you can also click).
9. Choose the result that looks like the best fit by putting a checkmark to the left of it.
10. On the right side of the screen, again click add to search builder.
11. When you want to to run the search, click Search PubMed.
The search above will show you all articles which have medical subject headings of Arthritis, Rheumatoid and drug therapy — thus, all articles which deal with drug therapies for this particular condition.
