A sourcebook is a collection of texts on a particular subject intended for use as an introduction to the subject.[1] The selected texts are typically edited, laid out, and typeset in a uniform format before binding, and the result is often a hardcover book similar to a textbook. In contrast, course readers are prepared by simply photocopying or scanning the selected materials and then adding covers, front matter, tables, and pagination, they are usually bound as softcover books, and they are usually prepared for a specific course.
