\noindent This is a list of all corrections made to {\sl Computers \&
Typesetting\/} since the publication of the final printed versions of those
books. Corrections made to the softcover version of {\sl The \TeX book\/} are
the same as corrections to Volume~A\null. Corrections to the softcover
version of {\sl The \slMF\kern1ptbook\/} are the same as corrections
to Volume~C\null. Changes to the mini-indexes
