Fishing books range in quality from those with pretty pictures but little useable information to invaluable guides to catching specific kinds of fish. First, decide if you want a general guide to many fish or information about your favorite fish. For instance, if you want to do just coastal fishing then it's really pointless to get a book that details catching freshwater panfish.
Next, consider the type of coastal fishing you will be doing. Inshore fishing is different that offshore fishing, and the species of fish that inhabit those regions are different also. Chances are, you're not going to catch a 600lb Bluefin Tuna in Barnaget inlet. My advice to you would be to "match the hatch". Look for and buy books that are specific to the types and areas of fishing you're planning on doing. Then, when you're all set to go out and catch those monsters... invite us all to join you.
PS... Some of the best fishing information I've ever gotten was by hanging out at bait and tackle shops. It might take you an entire summer, but as locals get to know you they'll start sharing little secrets. Try to find a shop that serves coffee and donuts. These places will be frequented by local fishermen before and after a days fishing. Be the complete novice and respectfully ask questions and listen to the replies. Old salts have more local knowledge than any book you'll ever be able to buy.
