Subject: Re: book recommendation
This seems to match what you had, but the last thing I need to keep track of this in realtime is the source of CPI data you are using.

I tend to use my subscription from Pinnacle for a lot of things, including CPI.

But if you want the official CPI release, it's free but they don't make it easy! It seems they want to force you to see the year-on-year increase, not the index level.
Go to this link and search for CUUR0000SA0, ignoring any line tagged M13 (which is annual average)
