The 99 year pdfs we have here on the site are terrible, they combined 1/2 and 3/4 volumes so it two 3000 page pdfs, horrible loading times and lag when scrolling.pdf would be just fine, if the boneheads would break each section into it's own file. As is, the files are so enormous that they can't be scrolled with any precision.
So, yeah, I like paper, but I deal with .pdf when I have to.
The '88 service manual I have was copyrighted in '86. Kinda explains why there's so many errors.
