In fact, citing the source is not a reason to copy its phrasing, syntax, or ideas too closely without quotes. Thus, using patchwriting, mosaic borrowing, and paraphrasing without any substantial changes still amounts to plagiarism even if the source is duly listed in the bibliography.
Therefore, it is a good idea to quote verbatim, convey original ideas in new sentence structures, and give credit to specific ideas, not entire sources.
