Opinion on the best beginner books to start with
Carol Walker's "DNA* Dulcimer Ditties" Book 1 is a great starter book, especially if you're interested in chord-melody style playing. The dulcimer club here recommends it for newer players. She teaches techniques using a lot of familiar songs, and she provides fingering recommendations so you'll learn how to play the chords as you go. Her store page has a sample tune from the book so you can see what it's like: http://www.musicladycarol.com/store.html
If you're interested in fingerpicking, I'd also recommend Janita Baker's "Fingerpicking Dulcimer" book to go with it, and Sue Carpenter's "Patterns and Patchwork."
