he sixth edition of Schalm ’s Veterinary Hematology has undergone signifi cant updating, reorganization, and refocusing. Several global changes have been made with the goal of making the information more accessible and improving cohesiveness and readability of the text. First, we grouped topics within established disciplines in hematology. Secondly, we introduced informative chapter outlines at the beginning of each chapter and extensively refer the reader to other chapters within the text. Finally, we edited the text in an attempt to make the presentation as clear and uniform as possible.
