Thank you! Much appreciated.

When I started out on this forum I was looking for a post like this one, but couldn't find any. Luckily some of my friends have been working in this space for a while, so I asked them, and found a few on my own. I generally prefer books as they have to go through a serious vetting process; another good way to check quality is to look at the publisher and google the author (some publishers are better than others). Hope that helps.
