I just added an old book to GR which lacks ISBN numbers (it's from 1950). The cover of the book is just a blank grey page (which I haven't got access to), so not much of a cover. The user who asked me to add the book has scanned and provided the title page which contains the author name, the novels included in the book and the publisher. Can I add the title page as a cover for the book or should I let the entry be without a cover?
