Ask HN: Where do you get your reading material from?

Where do you get your technical reading material from ? Engineering Blogs/ Books / Guides / Tutorials ?

From technical learning for new topics, I am using safaribooksonline.com on a trial basis and so far I have liked the experience of being able to read from whatever material I want.

Are there any similar services out there which are more affordable?

For the ones who have used it, how do you rate safaribooksonline ? Is it worth paying the hefty subscription fees?
