While the publication date of 1985 would appear to make this volume irrelevant and outdated, it remains a sought after and highly specialized title that will fetch a premium on the marketplace, especially considering the lack of copies available via a simple BookFinder.com search.
The moral of today's online bookselling blog post:
Don't overlook or discard Medical Textbooks simply on the basis of their publication date, as several remain seminal works in their respective fields. Having said that, I'm sure you're aware that 99% of these titles will not be worth their weight in recycled paper, but developing a feel for the right types to look for will result in some excellent sales over the length of your career as a bookseller.
Here are a couple other examples of relatively scarce Medical textbooks I have sold for three figures (or even four figures in one case) in the past year alone:
Heart and Coronary Arteries: An Anatomical Atlas for Clinical Diagnosis
Published in 1977, Sold for $1000
Congenital Malformations of the Heart
Published in 1975, Sold for $500 (with one additional copy available for sale)
The Lymphatic System
Published by John Wiley & Sons, in 1974, Sold for $750
Please feel free to share your experience with outdated medical textbooks in the comments field below. Also, I am currently in the process of cataloging a particularly impressive 30 plus volume set of facsimiles of Classic Medical Texts. I look forward to sharing this phenomenal discovery with all of you in the near future.
