I love it when I can find some of my stuff in use – I sell hundreds of images every day, and yet I rarely see where they are being used. It makes me sad 
If you go on amazon.com and search for your username, in my case “thesupe87″, you will see a list of books that have credited you in the text somewhere in the book.
This book featured my 3d cells image as part of the cover:(
Pocket Guide to Colorectal Cancer: Drugs and Treatment, Second Edition (Spiral-bound) by Gail M. Wilkes ISBN-10: 0763761737 ISBN-13: 978-0763761738
I guess I have an image on page 33 somewhere in this book – I can’t seem to find a preview of it online, though.
Essential ICT for WJEC AS Level: Student Book (Paperback) by Stephen Doyle ISBN-10: 1850084130 ISBN-13: 978-1850084136
I also have an image in this one, on page 7. Not sure which one, but the section is about the kitchen I guess.
Knack Organizing Your Home: Decluttering Solutions and Storage Ideas (Knack: Make It easy) (Paperback) by Emily Wilska ISBN-10: 1599213877 ISBN-13: 978-1599213873
books.gooogle.com is also a great place to search in order to find some of your images in use. Here are a bunch of mine that I found, with actual previews:
