Which version of the FAA's Instrument Procedures Handbook is current? I'm looking for the current release of the FAA's Instrument Procedures Handbook. The FAA website for the IPH shows FAA-H-8083-16, but other FAA documentation I've found references FAA-H-8261-1A. I've looked for places to buy the Instrument Procedures Handbook such as Amazon and found that they're offering FAA-H-8261-1A.

Which one is current?

For future reference, how do I found the most recent release of an FAA publication?
8083-16 ,dated 2014, is current version, superseded 8261-1A. It is stated in Summary of Change.

For future reference, the FAA page you linked in the question is best resource available.
