The titles were so radical. As a teenager, I never "dared" to order any of them. But they were always out there, advertising a radical life of a career in, well, for example, murdering people. Seeing such titles definitely left an impression. Of some strange sort..
Same here, just reading the catalog was eye opening. I still remember the disclaimer in the Loompanics books.”Not for sale to prisoners or Canadians”.
I was similarly going to mention Loopanics press which i used to collect. (principia discordia, lock-picking)
