Given that there are a total of 251 books over all decades, how long is it anticipated that the voting period will be?
It seems to me that it is quite likely that no one of us will have read all the books nominated, and each one of us will need to determine not only what constitutes the 'best' book per decade for us, but also whether we intend to read any of the other books in the various decades to 'test' the strength of our decision.
There are expedient ways around this volume of nominees of course, and that is to selectively read the book or part thereof, but this may still take time.
So .... the voting period should be ..... 4 weeks ..... 6 weeks ...... 8 weeks ..... ?
