Introductory References for the Black Hole Information Paradox I am looking for introductory references for the Black Hole Information Paradox and trying to compile a sequential list through which someone familiar with the basics of QFT and GR can go to understand the above-mentioned from ground-zero.
The requirements that must be satisfied are that the list should contain notes/papers + lectures and that they should build things from absolute basics to go up to the most recent advances in the field (maybe with some references for the quantum extremal islands program). Of course, there are a lot of papers, especially in the most recent advance regime, but I am only looking for the ones which are simple and easy to understand for self-study + they get one acquainted for research on their own into the field.
Some of the references that I have are in order -
0a. Warm-up 1: Sabine Hossenfelder's video - 10 things you should know about black holes
0b. Warm-up: Sabine Hossenfelder's video - How do black holes destroy information and why is that a problem?
0c. Warm-up: Sabine Hossenfelder's video - Solutions to the black hole information paradox
Now, the actual stuff:-

*

*Introduction to Information Theory - Edward Witten @ PiTP 2018 - To get a feel for what information theory involves and what kind of different entropies there etc. ( I feel various other videos from PiTP 2018 can be useful here, inputs are very welcome).


*arXiv:0803.2030 - Samir Mathur's introduction to the paradox


*Tom Hartman @ HMI 2020
4a. A Tutorial on Entanglement Island Computations - Raghu Mahajan @ IAS
4b. A longer version of the same - Raghu Mahajan @ ICTS
Please suggest modifications and improvements on this. I am just getting started on this topic myself and don't really have any idea which might be a good resource.
Edit 1 :
I have gone through the first two lectures by Hartman at HMI but they are not a good match for me. Things are not clear to me as a beginner.
 A: I am researching about the same topic and some resources I am using are:
-Les Houches Lectures on Black Holes by Andrew Ströminger: although maybe outdated, it gives a good introduction to how to understand Penrose diagrams along with some examples.
https://arxiv.org/abs/hep-th/9501071
-Lectures on Quantum Gravity and Black Holes by Thomas Hartman: they cover a wide range of math and physics introducing the most important tools to get started (I haven't read these yet).
http://www.hartmanhep.net/topics2015/gravity-lectures.pdf
-Holographic Entanglement Entropy by Mukund Rangamani and Tadashi Takayanagi: a bit more specialised towards holographic entanglement entropy, not only BH per se. They start with an introduction to entropy and the replica trick in QFT. Then they discuss the RT/HRT proposal (main formula for computing entropy in holographic theories) and give some examples. The rest of the book is more specialised, but gives some nice advancements in the field.

I hope this will help you! I'll be keeping an eye out on this post since I'm also searching for some good resources.
