If I were you, I wouldn't be so afraid of outdated material. You'll never find much current material on a rare - but fun - opening like Evans. You build your own theory through your games and not least the analysis of those games.
Some of the best analyses you will probably find in books more than 100 years old :-)
Mihail Marin's Beating the Open Games (2nd ed.), Quality Chess 2008, have a good chapter on the Evans Gambit.
Here is a link to GM Pereishteyn's video on how to play against it as black. As you already know, understanding your opponent's possible replies are a great way to improve your understanding of an opening.

You will likely find more videos on Chess.com that you should have access to with a paid membership.
I am only an advanced beginner, but I agree with @Toldsted, in that new ground is not likely to be broken on an opening that has been around so long. You will likely be better off searching for videos, including on YouTube, to learn different elements of your opening, including if the gambit is declined.
Thanks for the reply, I'll be sure to check out the video. With the help of stockfish and opening tree I've been kinda developing my own theory for Evans, trying to improve upon some inaccuracies played by grandmasters and so forth but still maintaining a lot of the common lines. I've watched chess.com GM Simon William's lesson on the Evans but it doesn't look at some common continuations so I've been working on improving my knowledge on some of those lines.
Well, first of all, there is an excellent little book from 2023 written by Richard Biolek and Richard Biolek Jr. (both are FIDE IM). The book is in Czech only. The book covers 4 gambits, but more than half of the book is devoted to the Evans gambit. The book is really full of variants.
I don't know Czech so I'm gonna be rather hesitant to purchase that, but thank you for the suggestion!
chess.com won't let me send a link to where they sell the book. Find it by ISBN: 9788087303900
Second, I made my own extensive database of games using Stockfish and the aforementioned book. This can be imported into some variant learning application. Here is a link to a sample: https://www.dropbox.com/scl/fi/zy5uh8snc6zwhdxlj3to2/evans_0109000.pgn?rlkey=utreagz2fxvisduwvca55go2o&dl=0
I can also send a far deeper database if you are interested.
Thanks so much! That will be a lot of help. I'll be sure to lyk if I need the deeper database.
Several books on Evans Gambit recommended here (near the end of the article) - particularly "The "Great Evans Gambit Debate" by Michael Rohde...
Introduction to The Italian Game, Evans Gambit & Two Knights Defense...

I used to look for good study materials and realised that many old books were already outdated. Modern video tutorials and detailed analysis of batches helped me out. In the process, I took notes to have quick access to information. I chose Excel for my notes because I was actively using it for studying at the time, and it was a good idea. It makes it much easier to organise and store information. At first, I couldn't figure out the formulas, but https://edubirdie.com/excel-help made it much more manageable. My notes for games in this format make it easier to analyse the game.
I'm a believer in watching videos that are up-to-date
Hi, I'm an intermediate player looking for a good book on the Evans Gambit. I've recently gotten the book Mayhem in the Morra by Marc Esserman and I'm stunned by the brilliant tactics and sacrifices shown in the book. I'm curious to see if there is any books that are on the Evans Gambit to allow me more in-depth knowledge on the opening. So far the more intriguing options I've seen are The Evans Gambit Revolution by Richard Moody and Evans Gambit and a System Vs. Two Knights' Defense by Tim Harding, but I'm worried that these books will have outdated information seeing as they were written in the early to mid 1990's. If anyone has any book recommendations for the Evans or any information regarding the two books I've mentioned I would greatly appreciate it.
