This is a request to add this. It seems to be an online course. Such a thing is neither on the list of valid book records or the list of non-book items. So is it ok to add or not?

From a quick review of the PDF of this book, it seems to be a textbook in ebook/PDF format for an online course. While textbooks aren't specifically mentioned in the Manual, my inclination would be to add it as allowable under either the Reference book or the Workbook classification.

Anyone have other thoughts?
