Welcome to collecting revenues!
As long as you don't buy the things I want of course!!! 
If you have not already done so, become a member of The American Revenue Association at
https://www.revenuer.org/ .
If interested in state revenues, join the State Revenue Society at
https://staterevenue.org/joinDownload every historical copy of "The American Revenuer" (TAR) from the website. I search this folder on my external HD constantly.
Also search out and download everything Ron Lesher has ever written if you even think you will ever have an interest in US alcohol related tax stamps, Scott listed or not, even if you aren't currently interested. I promise you will down the line. I am just now digging deeper into things I wish I paid attention to a long time ago!
