I love to visit the library and read a lot of books. However I am not particularly wealthy and consciously try to limit the number of books I buy for grad school. Besides the cost, there is a chance that the books may become obsolete to my area of work in a few years. Add to that, the space they occupy and the inconvenience caused during relocation.
I generally make notes of whatever I study and like from particular books. Sometimes though, I take a scan or photocopy of some chapters that are interesting or important from exam perspective. However suddenly it occurred to me that I may be inadvertently committing a mistake here. Is it not such scans that make it to websites that make available books for illegal download? Don't universities have explicit policies that prohibit such scans or photocopying of books?
Should I be more careful from now on with such photocopying? Is the info on whether a book can be photocopied available usually inside the book? Should I look into the university policy on this and the subsequent penalty for violators?
