Most fishing book lists mix a 32-page picture book with a 416-page manual and call them all good for beginners. They are not interchangeable. An 8-year-old will not finish Fishing For Dummies, and an adult starting out at 40 will get through Freshwater Fishing for Kids in about ten minutes. So the first question is who is reading, and the second is how much they want to read.
That is why this page puts the plain listing facts next to each pick: the age band and grade level where the listing gives one, the page count, and the year it came out. A parent buying for a second grader needs those numbers more than another paragraph of praise. Where Amazon marks an age band as coming from customers rather than the publisher, we say so. The adult and teen guides carry no age band at all, which is normal for adult nonfiction.
The ratings belong to Amazon's buyers, read off each listing while this page was built. Tom has not read every book here; they are ranked on what the listings publish and on how buyers rated them. Our short version: for a young kid, get Let's Learn to Fish!. For a teen or an adult starting from zero, get Wade Bourne's Basic Fishing. Check the current price on Amazon, since book prices move around a lot.
