Finding the Journal Article of Your Dreams
After you find a useful article, look at the reference list to find other applicable articles.
Use multiple databases
Do not just use PUBMED, try and use other databases as well such as Google Scholar (check validity of article) and BIOSIS.
KEEP TRACK OF ARTICLES
Download the article PDFs and organize them into folders based on your topic of interest. Mendeley is useful in this respect.
Reading actively and thinking critically while reading potential articles will cut down on the time needed to find suitable articles.
