You probably followed Aaron's blog series last year. Now it's becoming a book with revised articles, bonus material, a lovely layout, and fancy binding. A half-century of the history of text-based games. (You may recall that one of my games is on the list.)
I admit to mixed emotions about Kickstarter these days. They haven't backed off on their crypto horseshit. They haven't pushed it forwards much either, that I can tell. There was a followup post in February which doesn't say much beyond "We're listening to feedback." (I think you get the gist of mine.)
But of course I want Aaron's book to succeed. Which it has! -- it crossed the goal line as I was writing this post. Now I want it to do multiples. I also want Kickstarter to see pushback. Aaron has thoughts about this too; see the FAQ on his KS page. He also notes that there will be other ways to pre-order the book after the KS campaign is over. Read, decide what you want to do.
However you get it, the book will be a must-have for the shelf of the IF scholar. Or enthusiast. Or you.
