Searching PubMed using fields By

laboratory address Authors

Journal abbreviation

Putting fields to good use For instance, try entering three different queries — Down [AU], Down [TI], and Down [AD] into the For text box at the PubMed site.

When we ran those queries, we got (respectively) 275, 16,318, and 1,213 totally unrelated references. At least that narrowed the search a bit.

Using fields to find experts near you Suppose (for example) you just landed in Zagazig and you’d like to know if there’s anybody around who work on Plants. To get your personalized list of resident experts, just do the following:

1.Point your browser to the PubMed site (www.ncbi.nlm.nih.gov/entrez/). 2.In the For window, enter dUTPase [TIAB] Zagazig [AD], and click Go. 3.Click the list of authors (in blue, underlined). 4.Go back to the previous URL (after Step 2) using the Go Back button of your browser. 5.In the Display drop-down menu, change the display option from Summary to Abstract.

Searching PubMed using limits

A few more tips about PubMed

• Quoted queries “down syndrome” behave as a single word. • logical connectors (AND,OR, NOT) in your queries, as in dUTPase[TI] OR pyrophosphatase[TI] NOT Smith[AU] • Adding initials to proper names (for example, “Abergel C”)

• Write down the PubMed Identifier (the number in the PMID field) of that interesting paper you just found. • Don’t forget to deselect the Limit box when starting a new search.

-

- Spelling mistakes, wrong Don’t put too much initial field restrictions, or improper faith a search limitsinsettings can that all throw off an effective search. produces no results.

As a beginner researching a new subject, read through a couple of abstracts to enlarge your initial “jargon” vocabulary — and look for synonyms. For example, if you don’t know that some papers on dUTPase might use the term “dUTP pyrophosphatase” instead, you may miss out on some interesting papers.

• Try the Related Articles link — the one to the extreme right of the PubMed output — to enlarge a search that isn’t giving you enough references.
