I've just finished cleaning up and merging the first 28 sections of the linked HTML (Preface, Chapters 1-25, Notes and Packages) into a single PDF filtered via Readability. 312 pages of PDF that looks better on my mobile than the official PDF does.

Unfortunately my PDF is 4x larger and misses out on the Contents and Index sections as well as the images. The actual Lisp snippets look fine.
