重金求书：An Introduction to the Mathematics of Financial Derivatives, 3rd edition，Second Printing
注意，是secong printing，不是first printing。

2版区别的说明如下：
Candidates should verify that their copy of the Hirsa & Neftci textbook is the 3rd edition, secondprinting by checking that page iv, Notices section, begins with “Knowledge and best practice in this field…”.If the Notices section begins “No responsibility is assumed…” it is the first printing and should be replaced.
