One could do worse than to start here, a sub-site in the Edsa I website produced by Jason Tablante and Marc Orosa. Or here (the Wikipedia entry). There’s a work in progress over at Geocities. I know, I know; lean pickings. This was about all I could find. If anyone has other or better links, please let me know.
(Last year, a new law was enacted creating Ninoy Aquino Day. Does this mean this Monday’s a holiday?)
