George Grätzer is now Emeritus professor from the University of Manitoba. In addition to his best-selling books in LaTeX, Grätzer has proved to be a skilled author of several books such as “Universal Algebra"" © Springer 2008 and ""General Lattice Theory"" © 1998 Birkhäuser. Recently the author has published two useful and important articles in the Notices of the AMS relating to portability of LaTeX.
From the book reviews: If I really, really have to learn LaTeX, this is the book I'll go to in a flash. ... Even at a first glance or at first browse it's abundantly clear that this is a very good book for a TeXtyro like me ... . It's eminently practical and therefore eminently worthwhile.
