I've been frustrated by the fact that though there is a lot of C128 information available online, much of it is in the form of page scans or 'dirty' PDFs. For example, one of the books I found in PDF format consisted of scans of two-page spreads. There was no way to print this out cleanly.
Well, I've taken the time (quite a lot of it, as it turns out) to clean up some of these old PDFs, and to convert many of the page scans into PDF format as well. You should be able to print and 3-hole punch any of these books and manuals to have your own work copy without having to shell out a bunch of bucks for one on eBay or AbeBooks. A few (very few) were okay just as I found them, but I've mirrored them here just to have them all in one place.
I've trimmed, fixed, and organized pages, but I haven't edited any of the information. If there was a bad OCR, then it's still bad. If the scan was fuzzy, it's still fuzzy. Maybe someday I'll tackle cleaning these up as well. As it is, I have way too much time in this.
So, without further ado, here are the links to the books I've posted. Enjoy.

Ray Carlsen's Technical Notes for the C128 (compiled and converted from text) - http://home.mchsi.com/~airship1/Carlsen.pdf
The last one is a NEW compilation, consisting of all the Ray Carlsen technical notes I could find that pertain in any way to the C128. It's nice to have them all in one place, and in PDF format.
I also have the following, but have no more room on my server. Anyone interested in hosting them?
The C128 Programmer's Reference Guide (trimmed and reordered) - 41MB
Machine Language Routines for the C64/C128 (reordered a bit) - 28MB
The Transactor on the C128 (new compilation from images) - 80MB
The last item in this list is a NEW 280-page anthology of all of the feature articles ever printed in The Transactor on the C128. Though this took the lion's share of my time to put together, and though some of the page scans are far from perfect, I think it turned out to be a wonderful reference for the C128.
I hope you enjoy these. Please snuff them up quickly and spread them across the InterTubes, as I need the space back for other projects.
(Lance, if you'd like to take over hosting any or all of these, especially the ones I don't have room for, it would be great for me. The ones that are up there are taking up a lot of space, and I'm limited to five 20MB chunks, so I can't even find room for the others. Even splitting them leaves me with some pretty big files.)
