Bowerbirds non-fiction challenge

I read mostly non-fiction (as does the other half of Bowerbirds-Library - my husband John) and have a large number of titles that have remained unread or partially unread for a while. I have joined a 2013 Roots group in order to start to make a dint in this huge pile, however, it is increasingly obvious that it will take much longer than 2013 to read the list of books that I have come up with. Therefore I have joined this group so that I can continue my task during and beyond 2013.

I am currently reading Alfred Russel Wallace The Malay Archipelago.
