In most library databases, you can start by entering a search as if you were talking to a person or writing a paper.

After entering your search, look for a Filter, Limit, or Refine area in the display. Common options include article or document or publication type, language, and publication year. A "review" article or document or publication type is a good starting point, especially if you need to learn more about a topic.
Additional useful options:
- Author
- Look at other articles written by the most prolific authors
- Review articles are usually written by experts in a field. Once you find a review, search for other articles the author(s) wrote.
- Indexing (Concept, Index Term, MeSH, Subject Heading, etc.) assigned by subject experts
- Use these terms to find most of the references in a database about a topic
- Note: Articles newly added to a database won't be fully indexed
- Use the search box or "Search Within Results" to add additional search terms to narrow your group of results
- Substances or reactions (in SciFindern and Reaxys)
