Genres and Library Skills: A Topical Approach. This is an essay which appears in Academic Exchange Quarterly. It is by Susan E. Russell of the University of Oklahoma. This is aimed at teaching elementary students library skills.
From the site:
Children must be introduced to a variety of genres and writing styles to help develop their own interest in reading and writing. They must also develop skills in using the library and selecting appropriate materials. Through the use of topical units, the school library media specialist is able to introduce, in an interesting yet informative manner, the variety of materials that are available to students and how a particular topic can be depicted across a variety of genres.
