The Scriptures are up... I see I've neglected to link to them on the main home page, or the Archives home page, but you can get to them from the navigation menu. The interviews are up (though not up-to-date), and so are the designer diaries.
Also unlinked to are some pages preserved from
Oddworld.com, including some from the first, GT Interactive-owned official site, and some early Dear Alfs from the OWI-run official site.
You're not alone in wishing the Oddworld Library could be more extensive, complete and better maintained. I just wish I could find the time.
