Basic Search Techniques
Step 1: Enter Your Search Terms
Type any key word or phrase into the search box as shown in the image. Use an asterisk (*) to retrieve variations on a word, e.g., bacter* retrieves bacteria, bacterium, bacteriophage, etc.
For a Subject Search: Enter one or more words (e.g., asthma drug therapy) in the query box and click on GO. PubMed automatically "ANDs" (combines) terms together so that all terms or concepts are present, and it translates your words into MeSH terms.
For an Author Search: Enter the author's name in the format of last name first followed by initials (e.g., byrnes ca).
For a Journal Search: To retrieve articles form a specific journal use PubMed's Single Citation Matcher found below PubMed Tools in the center of the main search page or Journals in NCBI Databases found below More Resources on the the right hand side of the main page.
Use Boolean operators (AND, OR, and NOT) to combine topics in the search box if desired. Note: Boolean operators should be entered in UPPPERCASE and are processed from left to right. Change the order by using parentheses.
Step 2: Set Your Limits
Click on "Limits" as shown in the image. Choose the restrictions for your search, e.g. a specific language, article type, date, or subset of PubMed, e.g. nursing journals, cancer or bioethics.
Note: Limits remain in place until you change or remove them. Limits other than language or date will exclude NEW records that are "in process" or "supplied by Publisher."
Step 3: Click on the Search Button to Run Your Search
Step 4: View Your Results
Three results filters are displayed on the right hand side of the page: the 'All' filter tells you the total number of citations retrieved; the Review filter indicates the number of articles which are labeled as reviews; the Free Full Text filter indicates the number of articles that are freely available in full text. Click on the link to move to that set.
PubMed citations are displayed in "Summary" format, 20 at a time, recently added, except results that retrieve a single citation which will display the Abstract view. You can change the display for all or selected citations by selecting a new display format from the Display pull-down menu.
Summary Format: Short bibliographic citation
Abstract Format: Bibliographic citation plus abstract of the article. Use also for links to full-text.
MEDLINE Format: Full citation tagged with field labels. Use for importing into bibliographic citation programs such as EndNote.
After displaying your search results, view single records by clicking on the title of the article or mark a set of references by clicking on the boxes to the left of each citation. To increase the number of citations per page (up to 200) and to change the order of the citations displayed, e.g. by journal title instead of date, use the Display Settings pull-down menu.
Use the Send To pull-down menu to place citations on the clipboard, if desired, for later review. Otherwise, follow the steps below to see full text, print, save, or email your list or order articles.
Step 5: Connect to Fulltext, Print, Save, or Email Your Citation List or Order Articles
Links to Full Text Documents: Display references (either all of them or the marked citations) in Abstract format. If the U Get It! button appears (see above picture), click on it. It will lead you to the full text of the article. Some other online database services also link directly to the free full text of the article, such as SpringerLink or Wiley InterScience.
If no online full text link appears, go to the USD Journal List to search by journal title abbreviation and determine if it is available electronically or in print.
Save: Select the references you want to save by checking the boxes to the left of the citations. Place all your references on one web page by changing the Items Per Page number in the Display Settings pull-down menu. Select File from the Send To pull-down menu, choose the desired format and the order in which to sort the references and click on the Create File button. When prompted by the operating system, provide a name and appropriate extension for your file.
Email: Select E-mail from the Send To pull-down menu, select or fill in the options for format and the order in which to sort the reference, email address, and any additional text you want to add. Click the E-Mail button.
Order Articles: Use the pull-down menu of the Send To button to select Order and click it. This will connect you to the Loansome Doc Service to order copies of journal articles for a fee. Registration is required to use Loansome Doc services.
