In most cases, reference materials cannot be checked out of a library, although you are free to use them while you're there and photocopy pages that you'd like to study later. With all references, be sure to jot down the relevant end note or footnote information if you'll be referencing any of the material in your paper. This is important to do whether you'll be paraphrasing, quoting, or just referring to the information. For help creating accurate end notes or footnotes, refer to the citation resources listed at the end of this publication. While books, periodicals, and library reference materials may be the most common resources for research papers, there are other sources that may prove just as useful.
Videos are one example.
Libraries are a good source of videos, as are professional organizations that specialize in a subject area. If your school has a media specialist, ask them if they receive video catalogs that you could take a look at. Also, television channels such as Discovery, The Learning Channel, and public broadcasting channels, as well as special cable programs, such as Nova, often list their upcoming programs in publications for school media professionals. Such programs are also good resources. Another excellent source of information is CD-ROMs.
