And the production quality is now crap. I just got a review copy for a book that’s priced at over USD 100, and the thing is literally inkjet-printed.
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
I haven’t had to pull the trigger (which I imagine would take some wrangling). Even though the book is no longe selling a lot, its price has remained reasonable.
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
The reason I negotiated copyright reversal is that when a book stops selling, presses raise its price to several hundred dollars. They reason that they can keep squeezing out a profit with a single sale. If I can claw the copyright back and put the book in the public domain, it stops that behaviour.
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
So you don’t know what presses I’ve been publishing with… but YES? 😉 Most academic authors do not have agents. Though I did negotiate with PUP that the copyright will return to me if they fail to sell a certain number of copies per year.

Maybe reading the original thread would help you avoid gratuitously dunking on somebody you don’t know. Just a thought. (If it helps, it was about how doing this would have the effect of enriching predatory academic publishers like elsevier).
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
The copyright of academic books and articles generally belongs to the publisher, not to the author. If one of your books or articles is in LibGen, it is the publishing house that will get any damages, not you. You may get additional royalties, but they would be a tiny percentage of the damages.

Yes, traffic cameras work, but it's a myth that people hate them! Survey after survey shows that most people support automatic enforcement (and often want more of it). This is a false controversy, fed by a minority of disgruntled drivers & journalists seeking narratives with conflict.

You don’t need giant amounts of high quality data to come up with serviceable accurate indices of prices, employment, etc. Sure, you would lose precision after the second decimal point. That’s not what the important decisions hinge on.

Chimichurri is not hot (what Argentines call “ají molido” is not spicy at all; think paprika, not sweet). The rest tracks. The function of chimichurri is to make overdone meat palatable. One day argentines will learn how to properly cook our amazing beef. Until then, we’ll always have chimichurri.

Cataract surgery removes the lens of the eye. They replace it with an artificial lens sculpted to your precise prescription. The primary objective is to replace a cloudy lens, but they fix the refraction as a bonus. LASIK sculpts the cornea.
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
Cataracts surgery eliminates your prescription, but it is done one eye at a time. Between surgery in the first and the second eye, you have perfect vision out of the fixed eye while still needing correction for the other. You address this by wearing a blank on the good eye.
Mauricio Drelichman (@mdrelichman.bsky.social) reply parent
This person could have just had cataracts surgery in one of their eyes, and are now waiting to have the other one done. The operated on eye would have no prescription, but they would still require one for the other eye.
