This is an ocr .pdf of the last three lessons (20-22) from "A Basic Course in American Sign Language," 2nd edition. It contains all of the examples, exercises, and vocabulary for those lessons, but does *not* include any appendices or indices.
The scanning is not wonderful, for which I apologize. My scanner doesn't handle books very well. However, the text is still legible and the graphics are clear, for the most part.
