Just as a whiney aside, I'd love to find PDFs of "Inside Macintosh" volumes IV and V, IV particularly. My Google-Fu has failed me miserably on those... no, wait, I'd never just Google up a PDF, those volumes are copywrited material and I'd be a bad person if I just read an unauthorized copy of them found on the Internet, etc, etc, etc...

I really hate what Apple's done with the "Legacy" documentation on their site, lumping it all into that "Legacy Mac OS X Reference Library" page with a terrible search engine. Until about a year ago they still had sensible, organized index pages for this material, and links to things like sample code actually worked. Eh. I guess it's all been consigned to the dustbin of history anyway. All it means, I guess, is if you want anything you'd better get it now before it's all completely buried by the Ministry of Truth.
