Project Moonbase and Others

I have not seen this particular book, but ~all of the contents appear in other collections by RAH. In "Requiem", (the final RAH collection), they have the story "Destination Moon", and other related materials, apparently the same as "Project Moonbase" here. I'm not sure about the 2 story outlines included here - they do not ring any bells for me. As always, the stories vary in quality, but there are lots of classics here.
