Hi - The NSH has a terrific coloring book what explains what we do and is really fun. It's meant for kids but I used to give it to "newbies" in our area. It cost a dollar I think. But whatever price, it's worth it. Cheryl Cheryl Crowder, BA, HTL(ASCP) Crowder Histology Consulting 4952 Alvin Dark Ave. Baton Rouge, LA 70820 (225) 772-2865
