Your nolo link essentially repeated section 107 of title 17
All we can do is cite examples of how it's done in our homeland, and the variety seen here.

I agree Purdue's citation practices are their rules and others can have differing criteria. They probably chose 500 words because someone asked how many words. Substantial, a word that leads to largely and mostly, could be 50.1 percent of the material. I gave those links as examples, not the final authority. Who knows the copyright laws of the TS's homeland? This is the downfall of a world wide discussion group, common standards.§ 107 . Limitations on exclusive rights: Fair use
Notwithstanding the provisions of sections 106 and 106A, the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright. In determining whether the use made of a work in any particular case is a fair use the factors to be considered shall include—
(1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work.
The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.
