When I was in highschool, more than 50 years ago, the major second year English project was to write a term paper. When my children were in highschool, they did the same thing. We had to follow the Chicago Manuel of Style which showed to how to cite sources and create a proper bibliography.
The Chicago Manual dates from 1906, and is currently in its 17th edition. So, the proper technique has been around for a long time!
There are other style manuals, but the principles are the same!
