Indeed, but not though 4 or 5 (plus) editions [1], are you seriously suggesting that a TECHNICAL publication would remain a
*set book* if it's academic credibility had been called into question?! If you do then you are dafter than a first thought. :~(
[1] my book was the 4th edition, not imprint,
*edition*.
Any fool can place content on the web, including you, for all we know you could be citing your own work. You really have no idea of academic research have you, your motto seems to be - "It's on the Internet so it must be true" - OTOH my motto is, 'It's on the Internet so it's could be wrong!'... At one time, when Internet access was limited to Govt. education and businesses, the Internet was a day-facto source for researchers but since the ISP/dial-up revolution of the mid 1990s it's become more of a hindrance, often leading people down wrong paths or even into a muddy quagmire of ignorant/intentionally wrong facts.

No, ex Morris and Austin (later BMC/BLMC/BL), ex Roots Group, and a couple of ex indi' design/test companies IIRC.
