In between printings of Laundry List Workbooks, some small changes were made to the Laundry List Workbooks.
Please rest assured that all the same content is in all of the books, save for the one sentence which was inadvertenently dropped in the first printing. The changes are here.
Because we added a half title page, a second copy of the schematic to the appendix and combined the essay that accompanies it into one, the pagination and the Table of Contents had to be changed as well.
Publishers only change the "edition" of a book once a substantive change is made to the content. When a book is published, certain changes are spotted and modifications are made without labeling it a "Second Edition". The modifications we made between printings did not change any of the content of the book and were not substantive.
One can tell the which printing of the book they are using by reading the numbers on the Copyright Page. The first number in the series signifies the printing and the last number signifies the year of the printing.
Sincerely in Service,
Larry A., Chair, Literature Committee
