Yep, by all means read the Bowyer's Bible....but it has a lot of terminology that you might not know. If I were you, I would do a search for archery terminology, and ask questions here, before spending a lot of money on books. Don't get me wrong, the books recommended earlier are excellent. In fact, if you don't read the Bowyer's Bible, your bow-building experience will be a lot like trying to drive cross country without a map.
You should start with something very simple...a dry sapling....a hardwood like hickory, hophornbeam, or elm.....something that you can get for free......and don't try to make it too powerful. You can make more powerful bows as you skill increases.
Some people recommend backing your first bow (for safety). Personally, I start off newbies with the simplest bow possible: a self bow made from a sapling.
