This was a great book, as was his THE WORLD OF STAR TREK analysis of the series and Trek fandom.
In the TRIBBLES book, he included a tribble pattern. Not that it was that complicated, but including it is was caused my sister to get some artificial fur from a craft store and whip up a tribble for me on her sewing machine.
I had it for 25 years, and only got rid of it when it seemed probable that it was more dust mite-filled than polyurethane.
I met David Gerrold last year at Dragon Con.
