I had the 2012 print edition. One of the best books available - the best book that I knew - about GC at that time.

Anti-pattern: Regarding the 2023 e-book edition, I do not see a way to buy it from the site, or even a link to buy.

I thought I was missing something but figured they just didn't have a link to purchase it. I ended up going to the publisher's site to track it down:

How on earth is the ebook more expensive than the physical copy!

And it's not an actual ebook. You have to create an account on the "ebook" provider's site and read it through their website or app.

Worthless.

I hate when they do this. I'd rather just buy the physical book, donate it to a library and then obtain the liberated version of the ebook "elsewhere".

The physical copy will only get used by one reader (at a time). The ebook is going to be, err, "liberated" more often than not around a dorm?

In all seriousness, this is likely a nudge to a preference they have for how they want to sell this and how you should want to buy it.

They advertise the ebook as having interactive features and more compared to the print version. Shouldn't it be the preferred one?

I have the 2012 print edition too and fully concur with the assessment. The best book about garbage collection at the time (and maybe still?)
