Hi,
I'm also new to this, but I found the following useful (apologies for the weird formatting):
Books Web design Steve Krugman - Don't Make Me Think (and the sequel)
Presenting information
Edward Tuftes - http://www.edwardtufte.com/tufte/books_vdqi
Highly useful books about presenting statistics and information visually
Websites
Personally, I find Smashing Magazine good for articles that give you a lot of examples e.g. "50 examples of dark websites.. " I guess it's more for picking up tips and tricks. I find that the articles on these websites focus more on the basics.
A List Apart - http://www.alistapart.com/
Design Shack - http://designshack.co.uk/
Resources
