The changing thickness of manuals

[JimP]

There is something satisfying about having a paper manual in book form, but the most important aspect of any manual, electronic or otherwise, is the indexing. This may be where PDF files are superior -- if you can't find the word you're looking for in the hard copy index, it can be a bit of a slog to find the relevant section. But I did always appreciate the old fashioned HP manuals -- and yes, even the old Microsoft ones too.
