Below you will find a list of Masonic resources that I recommend. If you know of something that I don't have listed here, let me know and I'll check it out and if I like it, I'll add it!
Whence Came You? podcast - an excellent resource for all Masons (and those interested in Freemasonry).
Christopher Hodapp's Blog - A blog by the author of Freemasons for Dummies
The Philalethes Society - The oldest independent Masonic research body
The Master's Jewel - absolutely AWESOME Masonic jewellery.
The Masonic Grand Lodge of Indiana - the Grand Lodge of my home state.
Mackey's Encyclopedia - a great digital encyclopedia of Freemasonry.
The Midnight Freemasons - a great Masonic blog with various contributors, generally updated Mondays, Wednesdays and Fridays.
Not a Mason and you'd like to know more about Freemasonry?
I highly recommend you check out Brother Christopher Hodapp's book Freemasons For Dummies, it's well written and will give you the basics.
