There are lots of materials out there. Not so much when I started playing, just a few books like Super System. The internet changed poker.
In 2003 the WSOP
went from 800, to 2500 in 2004, to 5600 in 2005.
Not only are there more players, armed with hundreds of thousands of hands played online and a new way to share information, the new generation of players, were and are, more difficult to play against as they have become looser and hyper aggressive (I love to watch Hellmuth melt down when 67s cracks his AA/KK).
I think books are outdated. They are great for nostalgic purposes, but have already been analyzed and picked apart, people are watching you play in the rear view mirror.
Blogs, interviews, and videos on the net are certainly the way to learn the "current" temperature and style of poker
. The important thing is that I could explain to you for hours how to ride a bike, but most likely you would fall on your face
. Some things are learned by "doing" rather than "reading".
I limit my poker studies to 2-4 hours a week. The rest of the free time I play. Don't put too much time into learning how others play, you need to be spending more time on developing your own winning style and exploring what works for you
. This can only be done at the tables.
Every week try to learn 1 new technique and implement it in your game. If it works, keep it, if not, leave it at the wayside, but much more time should be spent playing than reading.
