Ms. Dwana Callaway met me at the Texas Library Association (TLA) conference in Houston in 2009 and from that meeting a wonderful school visit was born. Ms. Callaway is the librarian at Hoffman Academy and she makes sure the library plays an active part in the education of her students. When she talked to me, she was clear that she wanted my talks to directly relate to the curriculum of students in grades 6, 7, and 8, especially to the topic of how to do research and write a composition. That's what they were working on at the moment. Gladly, I prepared a presentation about how I do research to write my articles and books. It seems that's exactly what Ms. Callaway and the teachers had in mind. They asked me for my notes and I was happy to share them. Thank you Hoffman Academy, and Ms. Callaway in particular, for a wonderful experience with your students!
