Viral Marketing Via Library Books?
Hard to believe, but I guess if a library's got to make money to remain open, this is one way to do it. I suppose the insert could always serve to mark the reader's page.
From the BBC, news that an advertising agency is planning on placing advertisements (adverts) in books in county libraries in Essex, Dorset, Somerset, Bromley, Kent, and Leeds. It aims to cover the UK by the middle of 2008 with around 3m inserts being made available per month.
