Tip • Quick Gold Glitch

Go to Winterhold, start heading up the path as if you're going to do the dragon bounty for the jarl, you will come to a cave called the 'Sightless Cavern'. Continue past it up and around a corner, you will come to an alter with skeletons.

Next to the alter there are Boots and a Shield. Picking them up will make the skeletons come alive.

After killing them, the skeleton that was on the alter will have a 'Book of Oblivion' in his inventory.

This book will never disappear. Continue looting the body for an infinite number of books worth 50 gold each.
