Combine Request - Fourth "R"/Brain Machine

[Rob]

Hope this is correct.

I created the title "The Brain Machine" by George O. Smith, which is a republication of "The Fourth 'R'" as a mass-market paperback. The original was published in 1959. The edition I am reading was published in 1968. It appears different than the 1975 hardcover edition, also listed as "The Brain Machine," although I do not know that for a fact.

The edition I am reading can be seen here:

I am hoping I am correct in recognizing this published edition as a valid "other edition." If so, can someone combine it with the others? If not, can somebody delete it?

Thanks!

Sure looks like a valid edition to me. Most 1968 books had no ISBN.

Combined and cover added.
