Depending on the size of your school, you may have a subject area librarian for the particular type of research you are doing. Just fill out the form, press the button, and have no worries! Secondly, information can be gathered in a number of places. Start writing.
Some examples are ERIC, the educational database, and Silver Platter, which offers texts of recent articles in particular subjects yep, the whole article is available right through the computer, which is often less time-consuming than looking through the stacks for it The American Psychological Association has the titles of articles on specific subjects psychology, sociology, etc.
This scholarly practice allows your reader to follow up that source to get more information. You will need to search much the way you would on the library database computers--simply type in key words or authors or titles, and see what the computer comes up with.
Also remember to record the call number, which is the number you use to find the item in the library. Use those sources with the most citations.
They are great places to start.
