This is a great little spreadsheet containing many, many hub and rim measurements.
The Excel does get updated. So, make sure to download the sheet periodically. Yes, if you are rebuilding a wheelset for customer Tony's beloved Bridgestone road bike, complete with the original 7-speed Shimano 600 hub set, you can find the flange dimensions for the hubset here, and with the time you save, since Damon spent his time making this great resource, you can briskly walk down to Betty's Oceanside Diner and get a cupcake.
If you've ever had your older hubset rebuilt, and you see Damon R., buy him a cupcake. Buy Sheldon one, too.
