Sometimes I'm amazed at the questions I come across.
The questions are good, my amazement is that so many people don't realise the fantastic resources that exist to answer them.
Of course Google is probably the best place to start ... but if you are looking for longer articles or better still presentations on a subject, plase check out "Slideshare". You can get into ithere or by simply typing www.slideshare.net
Some of the presentations are just a few "amateur" slides, sometimes hundreds of very professional ones too though.
In the past few months I've seen lots of requestions and question regarding "Brand Architecture" ... try entering this on Slideshare and over 70,000 presentation/articles are there! Free!
