Query: Apollo Lunar module Reference

This is a disappointing publication. The fact that it is ring bound is one "star" against it. It is very pricy for a ring bound 'book'. Worse however is that it is a photocopy of another publication (at least another star against it) and in some instances three pages of text are copied onto one page making for a mix of some pages in portrait format and others in landscape (yet another star against it). Because it is a photocopy some of the illustrations/diagrams are of a very poor quality. In addition, when three pages are crammed onto one page the font size, as one would expect, becomes very small. What is really disappointing is that there is a wealth of information here but poorly presented at best. I feel "ripped off" for having paid so much for a collection of loose pages. A hard cover, good illustrations with some in color, and quality printing and the cost would have been perfectly justified.
