Reading and learning to read are fascinating subjects. Holly and I both had undergraduate degrees in education and we have quite a few lively discussions on techniques and child development. We have come a long way in understanding how the developing child learns to read. For the most part, teachers during my time were breaking students into 2 groups: regular and special: there was no room for nuance. Toward the end of the 1980s and in the 1990s, there was real progress in diagnosis and treatment of dyslexia. In addition, accommodation to students with learning issues were very much a part of mainstream schooling.
This particular book was from an academic library and is a brief overview of the main working theories on dyslexia as well as treatment. It is well cited, but mostly a summary of work. In an academic library, this would be a pretty easy weed since it isn’t particularly deep. It might have been considered for a public library considering there were few materials and information at the time.
