I did not buy this Kindle edition. I was going to do so, since there are some pretty complete, multi-book anthologies out there, and I assumed this was one of them. But then I looked at the scant list of titles that are included, and I ran away. It just was not a good collection from what I could see. Two of the books of the Skylark series, but not the other two? ONE Lensman book ("Triplanetary," the first and the worst) plus the relatively unimpressive 'Lensman Sequel' book of "The Vortex Blaster," but not the rest of the Lensman series? Why could they have not included ALL of the books of these particular series? If it was a matter of lack of Copyright access, they should have just skipped the above books and added in some other works. As it is, I'm afraid the incompleteness of this collection will just prove frustrating, UNLESS you are only looking for some partial introduction to his best known works. If someone DOES buy this collection and can somehow show me that I am wrong in what I think is in here (from the list they give) then I will gladly withdraw these objections.
