Articles, books, statistics, how to cite references, and more information about the multidisciplinary field of public health.

Is My Information Reliable?

Your professors, employers, and colleagues will always need to know

  • whether you used information that was scholarly and dependable, and
  • where you found your information

The Evaluating Information guide will show you how to evaluate the reliability of information.

The Citing guide will show you how to list those information sources correctly and completely, so that others can find them.


Here is another way to evaluate information: always apply the CRAAP test to web sites or documents whose trustworthiness you are not sure about:

  • currency
  • relevance
  • authority
  • accuracy
  • purpose

Search for Journal Articles, News, Conference Papers, and More

Save your time! Use these search techniques:

  • Put quotation marks around PHRASES (two or more words), so that the words are searched together
    --- Example: "machine learning"
  • Put an asterisk at the end of words, so that you get all of the word endings
    --- Example: high* = high, highs, higher, highest
  • Start by putting your search words in the Title. If you get nothing, you can take them out of TITLE and move them to ANYWHERE.

Latin American and Caribbean Health Information
  • LILACS (Latin American and Caribbean Health Sciences Literature; English) -- This is a "comprehensive index of scientific and technical literature of Latin America and the Caribbean." Here is the list of countries which have contributed information.
         LILACS includes "systematic reviews, randomized controlled clinical trials, evidence synthesis, health technology evaluation studies, economic evaluation studies, clinical practice guidelines, technical reports, case reports and others."
  • Scielo (Scientific Electronic Library Online) -- Scielo was created in 1997 by BIREME in Brazil, which is a specialized center of PAHO/WHO. Scielo is "a model for cooperative electronic publishing of full text of scientific journals on the Internet to meet the scientific communication needs of developing countries, particularly Latin American and Caribbean countries. These journals are predominantly in Spanish and cover Engineering, Letters, Psychology, Health Sciences, and more." [description from CCNY database list]

Who else is doing this kind of work? How many times has this article been cited?

Have you found a great article about your topic?

  • See who cited that article (that is, mentioned it in *their* article)
  • See how many times that article has been cited by other authors

If the author of your favorite article was cited by someone else, there is a good chance that the citing author (that is, the person who mentioned *your* article) is doing similar work. (Remember that newer articles will not have had time to be cited by other authors.)

Databases that tell you the citing authors, and how many times an article has been cited, are:

  1. Scopus -- (see screen shots below)
  2. Web of Science -- (see screen shots below)
  3. Google Scholar -- Under each item on the left, it gives the number of citations
    NOTE: Google Scholar's number will always be too high, because it adds additional things such as lecture notes and Powerpoint slides.

In Scopus: Do your search, change the Sort to "Cited by (highest)," and click the number under "Cited by" next to your article:


In Web of Science: Do your search using "Cited References":

On the results page, click on "Citing Articles" so that the little arrow points down (meaning "highest to lowest"), and then click on the number next to the article whose citing articles you want to see:
