I've always found the authors who give these gifts to the hobby to be very responsive. A courteous and respectful email may yield the answers you need. Through various methods I've been able to find new TCR #'s assigned since the 10th addintion. As Mark Cotton's excellent Summer '07 CCTN interview with Knapp, Myers, and Wheelden showed us, these guys are constantly adding to their database. Lots and lots of work! I wouldn't presume to swamp KMW with a batch of dozens of chip # requests, just use some good sense.
