How to Buy Trump Sonnets (and How to contact Ken Waldman)
Small Press Distribution carries all seven books. You can order directly from SPD, or any good indie bookstore can order on your behalf. You can also buy books directly from Ken Waldman at an event (and he's happy to sign copies). He also sells books the old-fashioned way via postal mail, though only takes cash and checks (he really is old-fashioned, but at least is easy to reach since here's the information for you to write him, phone him, email him:
3705 Arctic #1551
Anchorage, AK 99503
and he's quick to get back to you).
