This document outlines Amanda Brasfield's taxonomy for library media specialist roles and collaboration with teachers. It presents a 10-level taxonomy ranging from no involvement of the librarian to full curriculum development collaboration. The levels include individual reference assistance, spontaneous interactions, cursory planning, planned gatherings, outreach, implementing major program elements, mature collaboration, and curriculum development. Examples are provided for each level to illustrate how collaboration increases with each level. Potential barriers to collaboration like time, personalities, schedules, and technology access are also discussed along with strategies to overcome barriers.
