I am writing some essays for some MBA courses and I will start writing my master thesis soon. I always prefer to source ideas out of books and journals, rather than online resources. Google Books is a miracle in the sense that I can find genuine free book resources and it allows me to verify any secondary and tertiary information I have.
However, I've been reading about this fair use rule recently and I am unable to answer this question now: if I want to paraphrase a specific idea (for example, the definition of "value" in marketing as stated in book x by author y), can I still go on and paraphrase it and include all the required citation? Is this still considered fair use? (I am asking this because I read that the fair use should be "trans-formative", yes sometimes I am commenting and analyzing others ideas but most of the times I am paraphrasing others ideas just for the sake of adding relevant information and literature review (especially in essays))
