Start with Byrne's three instructional books. The trick shot book and the book of pool shots are sort of optional, but there are a lot of semi-advanced ideas in the trick shot book.
Beyond those, in no particular order:
Ray Martin
Babe Cranfield for 14.1
For the mental stuff: Pleasures of Small Motions and The Inner Game of Tennis
One of Capelle's books depending on what you are interested in
Dave Alciatore's book
Steve Booth's book on one pocket
There are many pool books I would not recommend, especially the ones recently self-published. It is too easy to print trash these days.
Yes, many self-published books are no good. Not sure what you consider "recent", as self-publishing has been around for over 20 years. Before self-publishing, there were vanity/subsidy publishers, which are publishing companies that print about anything you pay them to print. They still exist today, unfortunately. They get their money upfront by charging the writer for X amount of books.
These types of publishers print the books and distribute them to the writer then the writer has to sell them. That is worse than today's self-publishing worldwide market platforms, because there are no online ratings that one can review, like on Amazon or whatever, before purchasing the book. You can only purchase these types of books (vanity/subsidy printed) from the writer's website, where feedback ratings and reviews can easily be controlled or completely bogus.
With that said, there are some very good self-published books available, as well as vanity published books, some older and some more recent. Bob Hennings books, Phil Cappelle books, and mine (

), are a few examples. Of course, many people don't realize these are self-published books, because a publisher's name is present. Anyone can start their own publishing company and use that name as the "publisher". It helps avoid the negative connotation that comes with "self-published".
In the end, the success of the book is what really matters, not who or what organization printed or published it. If it's good, it sells. The name of the publisher means very little, since vanity/subsidy publishing is available to anyone.
Examples of good self-published publishing names... BeBob Publishing is Bob Henning, which he started when he first published his own material. The Billiards Press is Phil Capelle. Bookymonster Publications is Brian Crist. And I'm sure there are countless others out there following this same strategy.
I find it useful to search Amazon for ratings/feedback. If a book has a rating of 4.0 or higher, it's likely worth buying. If it doesn't have a good rating, you might not get your money's worth. If it has no rating at all, can only be purchased through a privately-owned website, then you won't really know if it's a good book until you buy it and check it out for yourself.
