How to Write a Literature Review: Limits

• Most databases have predefined limits that can be applied to a set of search results
• These limits will refine your results
• Typical limits include:
  • Date Range (e.g. last 5 years)
  • Language (e.g. English only)
  • Article Type (e.g. review articles)
  • Full Text (full text of the article is available)
• Some databases offer additional limits, i.e. age groups.See the database Help pages under Limits for full list of limits.
• Caution: apply limits at the end of your search, applying some limits at the begining of the search, i.e. date range, can eliminate helpful articles from your results
