Henry Ehrenreich has noted that before the first edition of Introduction to Solid State Physics came out in 1953, there were no other textbooks on the subject; rather, the young field's study material was spread across several prominent articles and treatises. The field of solid state physics was very new at the time of writing and was defined by only a few treatises that, in the Ehrenreich's view, expounded rather than explained the topics and were not suitable as textbooks.
