How can we check if a book is a sequel edition of an older one with different names? How do you check if  a book is a new edition of an older book, but they have different titles, without accessing the books? Are there websites which maintain such records?

For example, is this book

Fundamentals of data structures in C / Ellis Horowitz, Sartaj Sahni, Susan Anderson-Freed.
Edition 2nd ed.
Published/Created   Summit, NJ : Silicon Press, 2008.


a newer edition to this one

Fundamentals of data structures / Ellis Horowitz, Sartaj Sahni.
Published/Created: Computer Science Press, c1976.


Does the second one have later editions?
I don't know if there's an easy way to track this. The Library of Congress catalog, for instance, shows no trace that the second book was an earlier edition of the first. However, if the edition numbers are consecutive, there's usually no "intervening" edition.
