Speaking of A.E. van Vogt

The kindly Mr. Isaac Wilcott, expert on all things Vanvogtian, was a great help to me when I was doing research for NULL-A CONTINUUM: he give me a copy of the original (and inferior) magazine version of WORLD OF NULL-A, but which had interesting clues and plot-threads later dropped from the book version I read as a youth.

Well, it turns out he has a short book or long essay on SLAN called SLANOLOGY available for sale as a downloadable ebook through Booklocker, the online publisher:

If any of you are as interested in all things Van Vogtian, I thought you would want to be alerted.
