With more than 40 lists of suggestions I've realised what a task it is going to be, complicated by the fact that some are just for books published in 2011 and others are for books read during 2011 regardless of publication date.
What I will produce eventually is
- a list of all titles suggested
- a list that shows which titles have been suggested multiple times
- a list of all authors
- a list that shows which authors have been suggested multiple times
