Which Textbooks Best Prepare for the IMO?

[Gravitational]

I am looking for some good mathematical textbooks to learn number theory, geometry, algebra at an IMO level. I wish to attend the IMO in two years time, so I have quite a while to prepare. For number theory, I was considering https://www.amazon.com/dp/048646931X/?tag=pfamazon01-20 just so i can get my feet wet, and then I will probably move onto some harder stuff. If you guys could recommend any other textbooks I will be grateful.

https://www.amazon.com/dp/0387982191/?tag=pfamazon01-20

is a training manual for the Olympiad. There is a newer edition but I'm not sure what the differences might be.

Finding someone who has successfully trained individuals who received high scores is very important to score high on the Putnam, tips and strategies that you would likely never find in time on your own can make all the difference there. I don't know if that also the case with the IMO.

For number theory, you might want to look at https://www.amazon.com/dp/0817645276/?tag=pfamazon01-20, subtitled From the Training of the USA IMO Team. You can view parts of the book on Amazon.
