Thanks for all the extra info folks. Amazing what data we have at our
finger tips thanks to the internet.
I am re-accomplishing my entire collection, from Harris huge 2 post
binders to 3 ring binders with Steiners pages & 67lb paper. What a job, but the good news is I am finding my mistakes from over the years along with additional I.D. that's required. Your links will help. I figured I might be done in a year if I work 4 hours a day at it!

Thanks,
Chuck
