There are some decent resources in here and there are some horrible ones. In my experience HN has never been a great resource for this kind of stuff.

I worked as a consultant for many years managing SEO for a number of fortune 500 style companies at a very high and detailed level. I lived and breathed nothing but this for years.

Practically the only book I have come across so far to date which I would feel comfortable recommending to anyone is this: http://www.amazon.com/The-Art-SEO-Theory-Practice/dp/1449304... however for the record they are releasing a new version of this book at the end of this month which you can pre-order here: http://www.amazon.com/The-Art-SEO-Mastering-Optimization/dp/...
