As I read the Dell omnibus version of The Universe Next Door for Eric Wagner's Schroedinger's Cat class at Maybe Logic Academy, I've been looking at the Pocket Books original version to see what was cut. For the most part, it's the lesser material that's been excised, but I did very much like this paragraph, from a whole chapter (from the "Terran Archives 2083") cut from the original novel:
Concerning that which we cannot know with certainty, we should remain honestly agnostic. The reader will, of course, form a purely personal evaluation of Wilson's grandiose allegories and occult claims; the trick is to concentrate on the reality projected through the printed page. Every sentence is a signal from a lost world, a time of primitive, barbaric splendor and fantastic cruelty with which you can interface synergetically by crossing over and entering the form.
I particularly like the last sentence.
