Come to think of it, if we are to have as many books on Shakespeare as there are professors of Shakespeare, future generations will have a difficult time at best of having a comprehensive grasp of their field. It seems to obtain now not just in the case of Shakespeare, but even of Eliot. But I didn't mean to say that just because an author has published a lot of books in a relatively short time that he or she doesn't have a lot to say. It raises the question, but doesn't necessarily imply the answer. Hence my query. Thanks, Ken A PS I believe Marshall McLuhan has now authored more books post mortem than when he was alive. So there is life after death....

Probably "until 50 would" be even better. The number of books which might have made a good essay constitutes about 95% or more of the books published by university faculty.
