This topic has already been described to some extent, e.g. here:
But I do no think that it has been completely discussed, especially in the context of related work and abstracts.
When I am writing the section about related work in my papers, I tend to describe the work of each other related researcher in a few sentences with my own words and referencing their papers. However, in a current paper that I am writing I have realised that the abstracts of more than a few papers that I want to mention are so well written and are so concise that I cannot do any better. Writing my description would be just a waste of time, and result in a less concise text.
So I am thinking about copy-pasting two or three sentences from the abstract of each referenced paper. And possibly adding, removing, or changing a word or two that may not be relevant in the context of the paper that I am writing, so it's not really a plain copy paste.
I have read that it may be a good idea to put quotes, but I find quotes, especially their immoderate use, as bad style.
Can I get in trouble for this? I would not go that far in considering anything of this as plagiarism, as the work is referenced and I am not taking credit for someone else's work.
Personally if one would do the same with my work, I would not be concerned at all, on the contrary, as long as not more than a few sentences are taken and the work is properly referenced, but you might have a different view.
