Nothing against a good reading list, just trying to explain the observation.
Anons back on /qr/ had been making some big "marvellous" mystery out of it, when I think this is nothing but a result of some of google's algorithms associating articles/texts written on google indexed sites to book titles mentioned on the same site or in the same articles.

An experiment would be to write an article about Q mentioning one of those trip codes, and further down in your article some arbitrary, unrelated book.
I'd bet that book would appear in the list for that tripcode some time later.

Eperiment the other way around: Once Q would re-appear with a new tripcode, chances are there'd be no books associated with it in a google search.
