Search vs. Research

  • Search is trying to find information by looking or seeking carefully and thoroughly.
  • Research is the systematic investigation into and study of materials and sources in order to establish facts and new research conclusions.

Primary vs. Secondary Sources

  • Primary source is an original document or object, something that was created or written during the time it is being researched. (e.g. dissertation, experiment, clinical trials, interview, journal article of original research, patient care records, statistics, presentation, etc.)
  • Secondary source interprets and analyzes a primary source ( e.g. bibliographies, books that discuss or analyze a topic, textbooks, commentaries, criticisms, index and abstracts, journal articles that discuss or interpret previous research, reviews of the literature, etc.)



Database vs. Search Engine vs. Browser

  • Database is a large amount of information stored in a computer system.
    • Data systems, statistics (e.g. Excel, Access, SPSS, etc.)
    • Bibliographic - Index & Abstracts (e.g. PubMed, CINAHL, Web of Science, etc)  Google Scholar provides online information crawling for individual papers not by indexing journals.

  • Browser is software installed on your local device that accesses websites and web pages (e.g. Chrome, Firefox, Safari, etc.)



Web Creditability

Several questions to ask to determine the creditability of a website:

  1. Who is sponsoring the website?
  2. How often is the site updated?
  3. Does the site present facts and not opinion?
  4. Who is the intended audience?
