Brian's suggestion of scanning the 6500 Pluto Camera plates sounds like a good thing to do, and I hope someone scans them someday. I think Dave has considered the project (at least, I remember overhearing the phase 'Pluto Camera' on occasion), but I don't know the outcome. We (meaning mostly Dave, of course; the staff gets involved by changing plates) have just finished the Lick Northern Proper Motion Survey plates and are getting ready to scan the SPM. Machines can generate far more numbers than humans can comprehend; someday, all of these billions of detections will result in some science. Plates have the obvious advantage of compact long-term archival, but they are certainly not computer-friendly. If anyone goes to the Sonneberg meeting, I'd like to hear a summary of the meeting, either privately or over the maillist. Data mining is getting to be a hot topic in astronomy. Arne
