For secondary sources, the student must give the exact citation. That would mean when within the text including page numbers. When in doubt, always cite . As stated above, everything not directly found originally by the student must be cited. Thus, an adequate research paper should have dozens of notes.
ALL sources used are to be listed.
This includes information from the Internet. Students are strongly discouraged from using encyclopedias as sources. Also, since notes presented in class have been compiled elsewhere, the student should not use them as a source but find the original source from where they came. Unless the topic is extremely current, it is expected that manuscripts outside of current media will be utilized. Finally, students should critically appraise any agenda that may appear behind the source, particularly when it comes to Internet sources.
