Some More Citation Helps

I'm still looking for helpful sites for writing footnotes.

An Oberlin professor has written a good chart.
I also found a youtube video
Son of Citation website (for building a bibliography)

Someone asked about noting information from the same source.  Below is some information:

Use of ibid. and op. cit.:

Gibaldi (313) does NOT recommend the use of these old-fashioned abbreviations: ibid. (from the Latin ibidem meaning "in the same place") and op. cit. (from the Latin opere citato meaning "in the work cited.")
For Footnote or Endnote citations, if you should see the term ibid. being used, it just means that the citation is for the second mention of the same work with no intervening entries:

³ Ibid. 12-15.

More commonly, author and page number or numbers are now used instead of ibid., e.g.:

⁴ Miller 12-15.

For second or later mention of the same work with intervening entries, where previously op. cit. was used, now only the author and page number or numbers are used:

⁵ Miller 198.
