Start with Jean Ritchie's book and then go to Larkin Bryant. Available at Elderly Instruments. There are also a number of threads relating to this....Enter dulcimer in the search box and read a boatload, from construction, to history, to playing methods.

There are a lot of really great books available, but the two above will make you a fine player and are very well done by two superb players and great indivduals.
