Yes. Mostly in digital form (O'Reilly Safari or whatever it's called now, though I don't know if I can heartily recommend, quality of titles has seemed to diminish in the offerings).

Occasionally will spring for a hardcopy book form.

True, most are outdated fairly quickly and few have long lasting value beyond 1-2 years. But when done right, nothing is better than a good text to guide you from beginner to intermediate, or intermediate to advanced. I've tried watching video but it just doesn't seem like an efficient mode (for most video courses, there are exceptions and wonderful video courses).
