While we try our best not to make mistakes in our books, sometimes they happen. In this document you will find corrections to errors that have been brought to our attention as well as clarifications; in these cases, the text as written is not incorrect, but we have found that some readers benefited from additional details. Corrections and clarifications are listed for each book, by design, page number, and printing.

To find out which printing of a book you have, refer to the copyright page. If a book is not listed here, then no errors have been reported. In the event that you find a problem not addressed here, please contact us.
