I have a printed copy of the TeXbook (from D.E. Knuth) at home. Now that I travel a lot, I don't want to take my library with me every time. Question:
Is there a legal way to obtain (=purchase) a PDF version of the TeXbook?
I know that there are non-official PDFs flying around in the internet, but I would really like to buy it.
\lstinputlisting{texbook.tex}
and you will get a PDF version indirectly and legally. DEK just prevented us from texingtexbook.tex
but he does not prohibit us to import it into our main input file. :-)texbook.tex
file is not legal. If you look at ctanhttp://www.ctan.org/pkg/texbook
it says:The source has protection against use to produce a document: such use is only allowed with the permission of the Copyright holder and of the publisher (Addison-Wesley).
