Thanks to trylobyte for the following.
Thought you might be interested in excerpts from the official LOST Encyclopedia. There are only 4 entries: Black Rock, The Tempest, Danielle Rousseau and Charles Widmore.
It will give you a taste on content of the Encyclopedia and the little answers that are given (actually it's more like clarifications instead of answers). Interesting bits are:
- Charles Widmore ordered the Purge
- Ben did want to release the gas in the Tempest and enact a Purge II to kill everyone on the island in Season 4
- Rousseau did not remember Ben when she captured him in the net
- Jacob gave Richard the suggestion to remove Widmore from the leadership.
