Selecting a Database to Search

A database contains a collection of articles from various journals and makes them searchable all in one place. No single database has all journals, so it is best to search in multiple databases. Below are databases that contain articles from science journals.

Search Tips
  • Keep your first search very simple. Start with only 1-3 search words. 

  • After your first search, start using filters or adding search words one at a time to slowly narrow your results down to what you want.

  • Many times, you won't get what you want on your first search. Searching is about trial and error, so you may have to attempt several searches using different combinations of search words in order to find what you need.

  • If you have tried multiple searches in multiple databases and still cannot find what you need, contact Suzi ( for searching suggestions or for an appointment.

Searching in PubMed

Always access PubMed through the library website, so it will know you are a TWU student. This gives you access to more articles.
