Principles: Any one part of a citation can be used to retrieve matching documents, but having two or more pieces of information increases the chances you will find the record you want. A Date can be entered as a year or with months and days indicated. In general, you will get better results only using the year. It is best to leave off the author's middle initial if you don't know whether it is used in the publication. Enter the name like this: Tallman M. It will retrieve any records that include a middle initial. One exception - if the author has an extremely common last name, the middle initial may be needed to narrow down the results. Examples: Complete the following citation: author: Levy J journal: The Journal of Infectious Diseases publication year: 2000 Click on Single Citation Matcher in the blue bar to the left of the PubMed screen. Click in the Journal entry box and type The Journal of Infectious Diseases. Click in the Date entry box and type 2000. Click in the Author entry box and type Levy J. Click on the Search button. Your search is run, and all matching citations are displayed. How many publications were indexed in MEDLINE that were published in 1998 by the author Tallman M? Click on Single Citation Matcher in the blue bar to the left of the PubMed screen. Click in the Date entry box and type 1998. Click in the Author entry box and type Tallman M. Click on the Search button. Your search is run, and all matching citations are displayed. Return to Table of Contents for this page Journal Browser The Journal Browser contains information about all journals indexed in PubMed. Principles: The Journal Browser can be searched by full journal title, words occurring in a title, ISSN, or MEDLINE journal abbreviation. A search on a word or phase will find all journals that contain it anywhere in the title. Two links are created for each journal retrieved. One will take you to a PubMed search for that journal, the other to more information about the journal and its publisher. Entering the MEDLINE abbreviation for a journal title in the Journal Browser will retrieve the full title, which appears no other place in PubMed. Example: Search for all journals with the word Cancer in the title Access the Journal Browser by clicking on Journal Browser in the blue bar to the left of the screen under PubMed Services. Enter cancer in the search entry box. In the resulting list, choose one of the titles and click on the ISSN. Examine the information given. Return to the results list by hitting the Back button until you get there. Click on the abbreviated title for one of the journals in the results list. A PubMed search will run on that journal title. Return to Table of Contents for this page Clinical Queries The Clinical Queries feature uses built in search statements in combination with your topic to find articles of clinical relevance. Principles: Four search categories are available: therapy, diagnosis, etiology, and prognosis Two levels of emphasis are available: sensitivity or specificity. Sensitivity will retrieve more records, specificity with find less. You may use Boolean operators in the search you enter. Examples: Search for articles on diagnosis of rocky mountain spotted fever. Try both levels of emphasis. Click on Clinical Queries in the blue bar to the left of the screen. At the next screen, click on the circle in front of the word Diagnosis. Click on the circle in front of sensitivity. Type rocky mountain spotted fever in the search box. Click on search. Examine the results. Click on the Back button until you return to the Clinical Queries screen. Click on the circle in front of specificity. Leave everything else the same. Click on Search. Examine the results. Using the History feature, compare the results of the two searches. Search for records on therapy for major depression in the elderly. Devise your own search strategy.
