Forum:SH:Author bio suitability question

I apparently violated some rule by typing out the full information in the back of a collection of stories about a certain author. I cited page and book title, etc., as the source of the information. My change was reverted, with a rather cryptic note, ending with "No dice." Are verbatim quotes (supplied by the person) from such a collection restricted in some way (such as copyright)? --GooRoo 05:33, December 15, 2011 (UTC)
