PubMed is the primary database for researchers in the fields of biochemistry, molecular biology, and related life sciences. It comprises over 19 million references to the articles published in more than 5,200 current biomedical journals from the United States and over 80 foreign countries. PubMed contains all of MEDLINE (1966-present), OLDMEDLINE (1949-1965),
PubMed In-Process records (new citations not yet fully indexed), and some
additional
non-MEDLINE
citations.
It was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) as part of the Entrez retrieval system.
Enter the author's last name first, followed by initials with no punctuation (e.g., Koshland ME). After 2002, PubMed allows searching by author with last name, full first name and middle initial (e.g., Koshland Marian E), or author with last name and initials (e.g., Koshland ME). To search for an author in the author field when only the last name is available, it is best to qualify the author name with the author search field tag [au], e.g., Koshland [au].
Enter one or more subject terms (e.g., molecular motors) in the query box and click Search. PubMed automatically combines (ANDs) significant terms together using automatic term mapping. If PubMed finds a phrase, it automatically searches the terms as a phrase rather than simply combining them. If you enter molecular motors in the query box, PubMed searches "molecular motors" as a phrase. If you do not want this, enter each term separated by the Boolean operator AND (use uppercase), e.g., molecular AND motors.
To retrieve articles in a specific journal, enter the full journal title (e.g., Current Biology) or use the MEDLINE title abbreviation (e.g., curr biol) in the query box. Qualify single word journal titles using the Journal Title [ta] search field tag. (e.g. Cell [ta]). Note: In the query box, an author's name or journal title can be combined along with subject terms, such as thorner protein kinase or curr biol protein kinase.
If you only know part of the journal title, go to the Journals Database, in the "More Resources" column. Enter the title words and click Search. For a list of MEDLINE journal abbreviations, click on the "Lists of all Entrez journals" link in the Journals Database.
Use to combine terms or phrases. AND, OR, and NOT must be entered in UPPERCASE. PubMed processes all Boolean connectors in a left-to-right sequence. To change the order in which search statements are processed, enclose a concept in parentheses, e.g., common cold AND (vitamin c OR zinc). Terms inside a set of parentheses are processed as a unit and then incorporated into the overall strategy.
Use an asterisk (*) at the end of a search term. For example, bacter* retrieves bacteria, bacterium, bacteriophage, etc. Truncation turns off automatic term mapping and the automatic explosion of a MeSH term.
Clicking on the "related articles" link next to a citation will retrieve closely related citations. This link also appears in the Summary screen, displayed directly under the citation.
To find review articles, click on Review in the right-hand column of your search results. Another option is in the Advanced Search, you may select Review in the Type of Article combo-box.
The Search Details box is located on the right side of the search screen. "Search Details" shows how each search term was translated using PubMed's search rules and syntax. It is useful to understand PubMed's automatic term mapping and search rules. Further reading is available in Advanced Search Techniques.
You can save your searches as RSS (Really Simple Syndication) feeds by running a search in PubMed, and click on the RSS LINK located above the search box. Once the feed is created, copy and paste the URL into the subscribe form in your RSS reader. Click here to read more about RSS feeds and RSS reader.
In Advanced search, previous searches can be combined or used in subsequent searches by choosing Search History. Combine searches or add additional terms to an existing search by using the pound sign (#) before the search number, e.g., #2 AND (#6 OR #3) AND microarray, or re-run a previous search.
After running a basic search, you may click on the Advanced Search tag to further limit your search by Topics, Languages, and Journals Groups section. For example, there are options for limiting by languages, types of article, subsets, full text or free full text, ages, gender, humans or animals.
Use PubMed's search field tags to refine your search strategy. Enter the specific term qualified with the appropriate search field tag. Below is a list of some of the more frequently used PubMed search field tags with examples of how to use them. A complete list of search field tags is available in the Search Field Descriptions and Tags section in PubMed's Online Help.
| Affiliation [AD] Author [AU] Journal Title Abbreviation [TA] Language [LA] MeSH Terms [MH] Personal Name as Subject [PS] Publication Date [DP] Publication Type [PT] |
Subset [SB] AIDS = aids [sb] Bioethics = bioethics [sb] Complementary and Alternative Medicine = cam [sb] History of Medicine = history [sb] Toxicology = tox [sb] Text Words [TW] Title Words [TI] |
NLM's Medical Subject Headings, a list of biomedical terms which are used to describe the subject of each journal article indexed in MEDLINE. The [majr] tag retrieves all MeSH terms that are marked as being of major importance in an article.
MeSH terms are automatically exploded by PubMed; that is, all terms which are logical subsets of the term entered are also included. For instance, vision disorders includes blindness. MeSH terms found using the "All Fields" search, however, are NOT exploded. If you want to turn off the automatic explosion, enter the MeSH term in the query box and qualify it with [mh:noexp].
This is another approach to advanced searching. Look up official MeSH terms to view hierarchical relationships to other subject headings and subheadings.
In the Abstract format
there are links to many publishers' web sites and links to the UC-eLinks service.
The UC-eLinks
service will provide access to the full text links, campus holdings and links

By default, PubMed results are displayed in a SUMMARY format. Citations are initially displayed 20 items per page with the most recently entered citations displayed first. Other formats can be viewed by clicking on Display Settings.
The Summary Format is comprised of: Authors, Title, Journal Source, PubMed Unique Identifier, record status for in-process or publisher-supplied citations, Related Articles, and Free Article link.
The Abstract Format is comprised of: Journal Source, Authors, Title, Affiliation/Address, Abstract, PMID, record status for in-process or publisher-supplied citations, Related Articles, Full Text Links, UC-eLinks, Publication Types, MeSH Terms, Grant Support, and Other Fields.
In the MEDLINE Format, all fields ARE formatted in two character field tags for downloading to reference management programs. MEDLINE is the only format that can be used to export to EndNote, RefWorks, or other reference management programs.
By clicking on Send to, "the selected" citation can be saved in a File, temporarily in your Clipboard, or permanently in MyNCBI Collections. You can also e-mail or print the citations.
Clipboard is a place to collect selected citations from one search or several searches. Citations are added to the clipboard by selecting Clipboard from the “Send to” pull-down menu. Once you have added items to the Clipboard, you can click on the Clipboard tab to view your selections. Within the Clipboard you can Sort results by author, journal title, or publication date.
Search results from databases can be saved in "My NCBI" using the Collections feature. With "My NCBI" you can save searches and data important to you, and you can set your preferences for NCBI’s tools and web site. Creating a "My NCBI" account is free to all users.
You can send up to 200 citations at a time through E-Mail.
In your search results, use the citation check boxes to select citations. You may move to other pages to continue your selections. If you do not make any selections, ALL OF THE RECORDS WILL BE RETRIEVED.
