If books that you'd love to have read could be implanted in your mind - which would you choose?

None.

I wouldn’t want to have any implanted in my mind. I enjoy reading a lot, so why take away a good experience?

Perhaps Steppenwolf and Romance of the Three Kingdoms. And I’d assume that we’re roughly 35–40 years from achieving this.

The realist in me: The dictionary and reference, as well as the contents of all of my textbooks. They are expensive!

The romantic in me: Everything written by Leo Tolstoy (I’ve read Anna Karenina, and loved it immensely and would enjoy more.) Religious and mythological texts from every background.

I’d be in favor of the idea, only if I could then remove it. I’d hate to have something planted in my head that I didn’t enjoy having there! Maybe they could invent a book on a thumb tack and you could plug it into a surgically inserted connection so the tack (book) part could be removed? It might be easier to sleep with a removable set up than having to hear it going day and night without stopping. And some of those Russian classics (which I haven’t read) are long!

Such a facility would have been useful while I was at school – but only if the material could be erased.

The classics. Almost everything I have to read for school (and then if I liked it, I could re-read it). Quite a few Big Stories in nerd culture (Ender’s Game, A Song of Ice and Fire, Hunger Games, etc) that I really have no interest in actually reading, but are such giants I sort of have to know a fair bit about them and be able to discuss (if only to win at charades).

The Memory Book: The Classic Guide to Improving Your Memory

None.
I re-read books that I read earlier in my life. I like the different perspective on it while read at a different point in my life.
Casting it to my gray matter is a silly concept to me and would loose something for me.

I see no fuss and muss in reading. Nothing like spending a few hours with a good book. Although for fun quotes and quick, philosophical insights I could show off with when attending the bar scene or some random search for the Cannibal god Kito, it would be pretty convenient to have Trainspotting at the ready in my mind.

I’d also say Steppenwolf and Romance of the Three Kingdoms, they hold treasures to me that can be applied to my daily life and thus would be nice to have at hand. However, I’d also add the rest of the works of Herman Hesse minus Siddartha, a couple essays by Schopenhauer, and a nice big old psychology textbook. and probably the 40k codices

Ack! Reading causes no muss and fuss. It’s an art.

I love the idea of sitting and scanning a page with the sounds of nature drifting through the window, even if the sounds are of traffic. I love the experience of being distracted by something out of the corner of my eye only to notice a spider weaving a web in the corner of the room. I like taking breaks to make tea. I love the exciting of turning the pages.

I love it all.

“The Best Poems of the English language,” edited by Harold Bloom. It’s my favorite collection of western poetry, covering everything from Chaucer to Hart Crane. I have a few of my favorite poems memorized, but it would be so cool to be able to call them all up from memory. The book is roughly the size and weight of a cement block.

Also, “The Oxford Companion to Wine.” There’s so much information in there, it feels like as soon as I learn one thing, another thing just slides out of my brain. It’s a thorough, fantastic reference book, and I’d love to have all that information right in my head.

@athenasgriffin has the most practical idea me thinks. I’d do the same. All sorts of dictionaries and language references that I could “look up” on the fly.

War and Peace
Hamlet
A Wrinkle in Time

Only reference books. It’d be great to have all that knowledge sitting in my little head, easily tapped on the fly.

Now, if the implant could encapsulate the experience of having lived the book, well my answer might be different. :)
