This is the best color atlas I have seen. As a student, this has proven to be an invaluable tool in laboratory. I have recommended it to every other student in my laboratory. The photographs have amazing clarity and consistency. The text beginning each section and descriptive text following each photograph provides indispensable additional information for identification and understanding. It is very rare to see the backgrounds for each of the photographs a pristine white, so that the fine details can actually be distinguished. Each section is written with great care and with complete forethought. Even though this may not matter to many, but to me, the fact that is was spiral bound shows the amount of consideration to detail the author put into this atlas. There is nothing more frustrating then trying to keep a book open to the correct page, the ability for a book to be able to be lain flat on a table, and the having no problems with binding (e.g. broken binding resulting in loose pages). The comprehensive index helps you find a cell's information and/or photograph with just one quick glance. The amount of pages doesn't even begin to show the amount of knowledge that is encompassed in this book. You can believe this, as I go thru my student courses & when I begin my career as a clinical laboratory professional, this book with remain on my shelves as a ready-reference for any questions I may encounter along the way.
