iBooks crash problem - possible fix
Had an experience of books app crashing and endeavoured to try and fix it - not much luck through the community or googling the detail so tried a few things - one thing that seems to cure it and it stayed and is still staying stable is to disable the background apps refresh completely from the General tab in settings. This seems to have been enabled to refresh every app I had on the iPad. Oh well will keep reading and hope this is a fix.
