An analysis of the second step algorithms in the Burrows-Wheeler compression algorithm

A paper by Sebastian Deorowicz. Implementing the BWT transform is nice and simple, but what you do with the transformed data is where all the action is. Traditionally, we use Move To Front followed by an entropy encoder. Sebastian talks about some alternatives that help compression.
