Referenced in an academic text book

My MSc project on memory management in the Linux kernel has indeed been referenced in an academic text book – Computing Handbook, Third Edition: Computer Science and Software Engineering – you can look me up in the preview there. The article that references my work is by the great Peter J. Denning, the “father” of the working set.

The book (one volume of a set) costs £157 so I am not sure if I am going to buy it just yet.
