Ageism – Stereotyping and Prejudice Against Older Persons (Todd D. Nelson, Ed.) is a mixed bag. It is loaded with very interesting research on ageism — my copy now has 18 post-it tabs sticking out. However… it’s written by academics, so you have to be able to tolerate academic-speech. I can, because I AM an academic, but it would have annoyed the pre-academic me. You get individual studies, but it can feel like there’s little overall consensus. But… if you wanted to understand the topic — or especially research the topic — this will give you fodder.
