\noindent This is a list of all corrections made to {\sl Computers \&
Typesetting}, Volumes A--E\null. It also includes all corrections made to
the softcover version of {\sl The \TeX book}, beginning with the
sixth printing (January 1986); these 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.
