History of Pandemics

In libraries, databases are a searchable collection of published information from a variety of sources, such as academic journals, magazines, government documents, essays, or multimedia.

• Use terms found in your background reading on the subject
• Use the Thesaurus or Subject Terms listings, if available, in the databases you are searching
• When you find a record for an item that is useful to you, look at its subject headings or descriptors for more ideas

If you get too many results— 

• Consider narrowing down the search terms in an Abstract or even in the Title field
• Try searching by Subject, rather than by Keyword (or by a combination of Subjects and Keywords or other fields)
• Try phrase searching (usually by using " " around the phrase)
• Use other limiters, if appropriate, such as a specific type of publication (Peer Reviewed, for example) or a specific time period

If your search does not yield enough results---

• Check your search to see if you entered it and spelled it as you intended
• Try other search terms and use OR between the terms to find items with any one of the terms
• Try using a truncation symbol (often an *) to retrieve results with varying forms of a word (educat*, for example)
• Look at the bibliographies of items that are closely related to your topic. 
• Search in a different database or ask a reference librarian
