I've used other reference books with "updates." After a while you can't find anything. You've got 4 places to look to find something. Keeping all the listings together and organized is very helpful, plus an update to deal with value changes would duplicate a lot of information, and the bloody book already needs wheels and a handle.

I think the ultimate solution is electronic quarterly distribution, with annual or less frequent paper suppliments. There is SO much more you can do with electronic distribution, including a pictography and other ancillary information. But the authors must be assured of a distribution means that isn't subject to "harvesting." Anyone with any ideas should jump right in.

Until then, I'm just happy to have Michael, Allan and Whatsisname contributing so much to this hobby. Thanks guys!
