Publishing info needs fixing

The book was first published in 1990 not 1960. Only thirty years out! It appears they've only published the hardback once, in 1990, so I would wager that it should also be added as the published date (as well as the "first published..." date).

Tracking and checking old editions, think I've caught all the rogues now.

Done. 30 years is nothing. I think our record is 65,000 years out.
