Everything is sourced in there. However it is not exactly what you're looking for since it contains many details while you're just listing events in a chronological order. Regardless I think you will still find useful to extract from this document dates and their related events such as:
- Founding of Interspace Corporate (later renamed to Interspace Commerce)
- Founding of Mactan's Lane Hackers
- Texas Incident (already listed - could be expanded though)
- Galileo Bypass Project
- Kepler Dark Matter Storm
- Founding of Leiden's Lane Hackers
- Rheinland-Kusari Embargo
Finally, it would be great if you add a link/reference to the Encyclopedia in your Liberty section post.
