Is the first edition of AI: A modern approach still relevant? • /r/artificial

Just picked up a super cheap copy of Artificial Intelligence: A Modern Approach from the local charity shop. The only problem is that it's 1st edition. As far as I'm aware the 1st edition is quite old now but since I'm just beginning to learn about AI, is it still ok to start with? I know some of the content will be obsolete but I would assume it covers the basics quite well?
