URBS 3992-002: Urban Studies Senior Seminar: The Built Environment (Panetta)

• MEDLINE, from the National Library of Medicine, is a comprehensive database of biomedical literature citations and abstracts - over 22 million of them. Areas covered include microbiology, delivery of health care, nutrition, pharmacology, environmental health, diseases, chemicals and drugs, psychiatry and psychology, biological sciences, social sciences and education, industry, humanities, information science and communications, and health care. You can access MEDLINE from many different platforms. I like PubMed, but try them all to the find your favorite!
  • MEDLINE via PubMed (Jennie's favorite!)
  • MEDLINE via EBSCO
  • MEDLINE via Ovid - In Ovid databases, you enter search terms one at a time and combine them later using Boolean commands (AND, OR, NOT) - refer to the Boolean Keyword Searching Guide for help.
  • MEDLINE via Web of Science

Boolean searching is based on an algebraic system of logic formulated by George Boole, a 19th century English mathematician.

In a Boolean keyword search, the terms are combined by the operators AND, OR and NOT to narrow or broaden the search (in CLIO, Ovid, and some other databases, you DO have to enter them in capitals).  This type of search is possible in most library catalogs and databases, but Google and other Web search engines do not carry out OR and NOT searches properly.

These Venn diagrams help to visualize the meaning of AND, OR and NOT; the colored area indicates the items that will be retrieved in each case.

AND

The operator AND narrows the search by instructing the search engine to search for all the records containing the first keyword, then for all the records containing the second keyword, and show only those records that contain both.

OR

The operator OR broadens the search to include records containing either keyword, or both.
The OR search is particularly useful when there are several common synonyms for a concept, or variant spellings of a word.

Examples using OR:
medieval OR "middle ages"
"heart attack" OR "myocardial infarction"
vergil OR virgil   

NOT

Combining search terms with the NOT operator narrows the search by excluding unwanted terms.

Examples using combinations of the three operators:
puritans AND women AND (massachusetts OR connecticut OR "rhode island" OR "new hampshire")
(adolescen* OR teen*) AND (cigarettes OR smok*)
reagan AND "star wars" NOT (movie OR film OR cinema OR "motion picture")
"zora neale hurston" AND (correspondence OR letter* OR diar* OR autobiograph* OR memoir*)
