Thanks to Sean's code-wizardry, it's now possible for us to provide you with on-going information on what data has been added to Pleiades, and what's slated to come next. You can view the information:
- with a web browser: http://pleiades.stoa.org/batlas
- with an atom-capable feed reader: http://pleiades.stoa.org/batlas.atom
- a KML-aware tool (like Google Earth): http://pleiades.stoa.org/batlas.kml
Or check it out in google maps directly.
