Q. I am using the Chicago style to cite a magazine article. If there is a “?” at the end of the article title, do I still need to use a period before the quotation marks?

Q. It is not uncommon in the literature of film studies today to have epigraphs that feature a choice bit of dialog from one of the characters in a film, and often the author of the screenplay is not given, but only the film title, character’s name, sometimes parenthetically the actor who played the part, and year of the film’s release. Similarly if one wants to quote a choice bit of dialog from fiction, say, one of Sherlock Holmes’ admonitions to Watson, does one credit Holmes and/or Conan Doyle? CMOS is mute on such attributions in the context of epigraphs.

Q. How do you determine which publisher to cite if the book has had more than one publisher over time, and which publication date do you use: the latest edition/publication date, or when the book was first published?

Q. How would you treat web page citations where access to the web pages is restricted?

Q. When writing an academic paper that is based on the analysis of one book, do you need to footnote each sentence that paraphrases an idea from the book or does the fact that it is known and stated that the entire paper is an analysis of the book’s themes sufficient?

Q. What is the proper way to reference an e-mail in a report?

Q. I am confused about how to cite a video recording of a live performance (an opera). It was originally performed and recorded by a Metropolitan Opera Television production in 1991, but a 2000 version (a rerelease in DVD format) is being distributed by another organization. It also comes in the 1991 version in the VHS format. It is important to distinguish between the two for a variety of reasons, especially if someone were looking for the DVD. The 2000 DVD is in German, but can have subtitles in English, Chinese, and French. How would I cite the 2000 DVD?

Q. How many lines of a published poem or song may be quoted in an article or book manuscript without having to obtain the author or lyric writer’s permission? And, what if the author or lyric writer is deceased?

Q. I am a writer and occasionally quote material from my own works, some that have been published and some that are not published but are available as working papers. Should I handle these quotations the same as I would those of other authors? What about paraphrased material—do I need to reference that? Does it make a difference if the material is published or unpublished, and if I hold the copyright or the publisher holds the copyright?

Q. I was wondering how I would cite an educational movie. Thank you.
