Once you have (1) performed a search in a database (2) reviewed the list of results and (3) evaluated a specific source from the results list what is the next step?

The next step is to obtain the full text of the evaluated source. This may involve accessing the article through your institution's library, downloading it directly if available, or requesting it via interlibrary loan. Once you have the full text, you can analyze the content in detail to determine its relevance and credibility for your research.
