It appears that I have much to learn about what staff of learning institutions are able to copy. Here is a link to the Canadian Copyright Licensing Agency to which many educational institutions belong: http://www.accesscopyright.ca/.
The concept of "fair use" comes into play as does the copying of partial works "less than 10%" for the purpose of private study.
The proper attribution of the work is also required to make the copying legitimate. I don't think copying a sashiko pattern out of a book, even if it is less than 10% is fair use. The students would take it home for personal use in a one day class even if it is a college accredited course.
Maybe someone out there can shed more light on this matter.
