Ctl+F: This trick is something most of us are familiar with but comes in handy when searching through lengthy scholarly articles. If you are looking for a certain word or phrase, use this to locate the section in an academic paper.
Abstracts and Conclusions: This is not a search engine trick but still a hack that helps get through length articles. Sometimes you want to know if a large article is worth the read. Reading the abstracts and conclusions can help determine if this article contains the evidence you need or if it is a waste of your time.
Tracking DOIs: Many academic articles and books will contain a DOI number, which stands for Digital Object Identifier, which is a unique number assigned to that publication so that you can easily find it. Always keep the DOI, if one is available, to make it easy to search for it later.
