Max Wintrobe died in 1986, five years after publication of the single-volume eighth edition. He had been the sole author from 1942 through the first six editions. Several coauthors joined him thereafter and have carried on his superb tradition in these volumes. For the first time they have called on an additional 33 contributors. This is the definitive reference work in clinical and experimental hematology. It is of interest to contrast the first edition of 51 years ago with this ninth edition. Cost has increased from $10 to $165; the approximate number of words from a half to 3 million; illustrations from 174 to 931; and color plates from 14 to 23. These increases have occurred particularly during the past 20 years.
While I sampled generously of several chapters, I picked "Chronic Lymphocytic Leukemia" by John Foerster to illustrate the way knowledge of a component of hematology continues to advance.
