There are tons of books and meditation courses. It depends what suits your style. eg, The Mind Illuminated https://www.amazon.com/Mind-Illuminated-Meditation-Integrati... is the most popular meditation book right now. There is even a subreddit dedicated to it. However, it is quite the read, guiding as one progresses, mirroring how a teacher would do it.
Culadasa, who made The Mind Illuminated, is working on another book that goes over the second topic I was diving into (like Noting Meditation). It is incomplete with no eta. It would be a 102 book for after one finishes The Mind Illuminated.
There are other resources on the second topic, but right now both topics are ideally taught with a teacher, especially the second topic, so progress can be aided and verified.
What goal do you have? I can possibly write a skinny as to what to look at and where to go to achieve that goal, including providing more resources.
Also, just in case you do not know CBT, with a good therapist, is, I believe, the only kind of therapy that works well on depression. CBT takes from the techniques in the topics above, and then boils them down into a light version that can be worked through at an accelerated rate.
