There is a freely-downloadable .pdf (4.8 MB file) of chapter 1 of my book, "Atomic Force Microscopy" available on the OUP web site. This has the preface and the whole of chapter 1.
This chapter contains background to AFM, and describes a few of the capabilities of the technique It explains how the technique was invented, and which instruments preceded it, and why AFM was needed. It also compares AFM to other microscopy techniques. The preface also contains information of the contents of the rest of the book.
The book should be published around 25th of March, pretty soon now!
