To celebrate the 75th anniversary of J.R.R Tolkien's The Hobbit - An Unexpected Journey and the release of Peter Jackson's new film adaption, we are launching a new online Hobbit community for reading groups.

The 1st of October is International Day of Older Persons and the UK's Older People's Day. The day is celebrated annually to recognise the contributions of older persons and to examine issues that affect their lives.

The shortlist for the 2012 Royal Society Winton Prize for Science Books, which celebrates the best in popular science writing, has been announced.
