  • Seeks to describe, summarize, evaluate, clarify and/or integrate the content of primary reports
reasons for conducting a literature review
Reasons for Conducting a Literature Review
  • Presents a theoretical framework
  • Provides a bibliography, analytical and critical appraisal of current literature
  • Refines, improves and adds to the body of knowledge
  • Informs and lends support to the researcher’s assumptions, definitions
  • Reviews previous scholarly and scientific work

software programs
Software Programs
  • RSS Feeds:  RSS stands for Really Simple Syndication.  RSS readers are software programs that collect, organize and display RSS feeds.  RSS readers allow users to scan headings from a multitude of journals or news sites. The benefit of RSS is that content from multiple Web sources is aggregated in one place.  RSS readers can be desk-top based or web-based (Note - web-based readers require no download).  
  • Some user-friendly web-based readers are Google Reader, NetVibes, and FeedBucket.
database systems
Database Systems


  • Nursing and allied health literature
  • Covers approximately 330 nursing and allied health journal references
  • Includes information on the title, author, journal, volume number, issue number, page numbers, date of issue, descriptors that indicate the type of article (i.e., research), and number of references.
search engines
Search Engines

Search engines: An internet program that searches for documents for specified keywords and returns a list where these keywords are found

  • Dogpile
  • PubMed

Basic steps to access:

  • Identify the key concepts of the research question.
  • Enter the significant terms into the search box.
  • Press the “Enter” key or click “Go.”

using the feature
Using the “+” Feature
  • “+"Dialysis" Outcomes: search will retrieve all documents containing the words Dialysis, but no documents that contain only the word Outcomes
  • Documents containing Outcomes must also contain Dialysis to be retrieved
using a wildcard
Using a Wildcard

An “*” is the symbol for a Wildcard

  • Allows for a search of words with variations in spelling by using the * after the first 3 letters of the word
  • Following a keyword with an asterisk (*) will search for the keyword and various suffixes
  • For a prefix, at least three letters of the keyword are necessary before using an *
using the operator not
Using the Operator NOT
  • Using the word "NOT" or a "-" before a keyword will exclude any document containing that term
  • For example: NOT cultural diversity will retrieve all documents containing the word diversity, but from these documents it will exclude all the results that contain the phrase cultural
