Misguided plagiarism phobia - is it a thing? (mainly related to difficulties in understanding English)
I must agree with chasly. 

I have come from the backgrounds of monastic education in Burma. They have a very different perspective on plagiarism. For these people, quoting an authority on the subject matter is for the sake of learned readers who will not believe an author on his or her own words. Therefore:

1) Even though the quoted text is in Pali, an ancient Buddhist language, translations are usually not provided. For, if you are a learned reader, you are expected to already know Pali.

2) The text is quoted only by title, or sometimes with the chapter title, but page numbers are never given. It means: if you are not learned enough to find out the quoted text on your own, you are not qualified to question the author's words.
