I'm reading a textbook on Ancient Greek that has readings at the end of each chapter. After I finish the reading, I would like to publish my translation to my blog, and above my translation reproduce the original reading. These readings aren't from classical authors, but were most likely written up by the author of the textbook, to provide simple readings for beginning students.
However, I'm not sure if it's legal to reproduce the Greek readings written by the textbook author. Would it be enough for me to cite the textbook within each blog post? Or am I required to actually write the author and receive permission?
Relevant Details
I live in the US and the book was printed in the US, and is still in print. It was copyrighted in 2000. I'm simply reproducing the textual content by laboriously typing up the Greek using the Polytonic Greek keyboard on Mac OS X. No pictures or scans.
The blog is a personal blog, devoted to my interests. Two of these main interests are Greek and Latin. I would say the blog has two purposes. First, it's an educational tool which helps me track my progress and access my materials. Second, it allows me to share my enthusiasm with others.
