I just finished creating pages for 2010, 2011, 2012 and 2013 podcast audio archives on the home page of this blog. On each page you will find the chronological list of podcast dates and their titles. It's impractical to archive old show notes here. Since the beginning of 2013, all show notes have been on this blog. If you're looking for them, just click the show notes link under "you can access" in the sidebar menu.
If you prefer accessing these shows in iTunes, just search for Guitar Technique Tutor Podcast.
