Fairly used

Alasdair Gray is perhaps not as well known in the US as he should be, though not for lack of Gavin Grant's trying, nor, for that matter his own enlightened beliefs about disseminating excerpts of his work:

About authors' property rights I am a Socialist who thinks nobody should pay for quoting less than 200 words. Nearly everyone who wants to use my illustrations and words — sometimes whole stories — is allowed to have them free if they are not a financially successful publishing firm. I think it a pity that the law has extended dead authors' copyrights from 50 to 70 years. I thought of adding a clause to my will making the copyrights of my books free for all, but my wife is much younger than me and depends on my income, so I did not do it.

We frequently receive requests for permission to quote from books we publish—often in non-commercial publications or scholarly works. Since we do not control such reproduction rights, we cannot deny or grant permission. Instead I sometimes try to sketch out a brief description of the doctrine of fair use: a doctrine that seems to be in danger of dying out from disuse.   It's not something made up by Lawrence Lessig and his pals at Stanford, you can read about it at the US Copyright Office. The University of Texas site also includes a helpful discussion.
