There are lots of tools you can use for lots of things especially given different disciplines but the one thing we all need is a citation manager. The sooner you find a citation manager the easier your life will be. I personally like EndNote. You pay for that but can usually get it free or discounted from your school technology center Some people like Zotero; it free. I like EndNote so that what I will talk about. With google scholar you can directly download citations into EndNote. You can also save the PDF of the article and attach it to your entry. This is how you begin to build your personal library. This is important. The body of literature you draw from will have core pieces and you will find yourself downloading and re-downloading things if you don get organized. Also there will be an article you remembered reading once and it will be perfect to cite in your current lit review but you won remember who wrote it or where to find it. This adds hours to your work that could be avoided by just getting into a routine. Find an article you like download the citation add the PDF to the EndNote entry. Whatever tool you use is unimportant it the routine that will save you. (NOTE Immediately after downloading a citation from Scholar you want to make sure the citation information is correct and all there. A lot of google scholar citations don have all the info. You can get it right away because youve got the manuscript in front of you. If you do this upfront it saves a lot of time fixing by hand later.) Another EndNote bonus is that you can use Cite While you Write a plugin for Word that allows you to insert citations into your . Then if you submit to a journal that uses a different citation style you can just click a button and the citations and Reference list will be reformatted automatically. This saves you hours of work that is otherwise done by hand. Also when you import a citation and create an entry you can add keywords to the entries and you can add notes. Keywords makes searching by topic really easy and the file is attached so you can find the PDF quickly. In addition to adding keywords I keep all my reading notes about an article saved in the EndNote entry (there a space for it). Taking good notes and knowing where to find them reduces the amount of time you spend re-reading an article or trying to find your notes somewhere. You will amass many of these documents over the course of your career so the sooner you can start organizing the better. This is the one tool you want to figure out as quickly as possible because the sooner you start using it the more it pays off. Best of luck to you!
