I'm teaching a course on computer-science paper writing, and I aim to turn my notes into a book for publication. It's designed specifically for Chinese postgraduate students who are writing their first paper.
In my course (and thus in the book), I use examples from real publications by Chinese authors. Moreover, I use LaTeX's \includegraphics{...}
so my quote is visually identical to what's in the paper. I then critique the writing: explaining what I feel is poor, and how I would improve it.
My feeling is that doing this for a paragraph or two with attribution is unproblematic, but:
I'm using a large number of snippets, totaling maybe hundreds from different papers.
I'm aiming to include a section along the lines of "how to proofread and optimize writing", where I take a single (short) paper, and painstakingly revise a large portion of it. I'm tempted to go through the entire paper, because it contains many examples of writing issues I see repeatedly, and because it's not possible to write one part of a paper in isolation from the other parts.
So...
Question: How can I write a book about paper writing which contains real examples without violating copyright?
I'm not sure what I need to know about this---it'd be my first book.
Update: Thanks for the responses! Virtually all the papers come from the ACM, and each paper lists the copyright; maybe 90% have an ACM copyright. The ACM's policies page says:
Course Material - Permission granted without fee if the course material is produced without charge to the student. (See Commercially produced Course Packs below)
So I'm confident I haven't done anything wrong so far; there's no concerns about me handing out ACM-copyrighted papers. And our university has institutional access, so the students have access anyway.
Also, at this point, I'm only just starting to put a book together, and I need to do this for the course whether or not a book eventualizes. I can simply keep copyright in mind as the book develops. Asking permission from the ACM seems to be a matter of sending an email; I don't know what they will say. (The authors might not be happy about me criticizing their writing.)
