Publisher Update: Continuum is now part of Bloomsbury Academic and we continue to represent them.
After Bloomsbury Publishing Plc bought Continuum in 2011, the new parent company has merged Continuum into their Bloomsbury Academic imprint for the Fall 2012 season. We continue to represent Continuum as well as taking on responsibility for the larger Bloomsbury Academic imprint - now distributed fully by Macmillan Publishing Services here in the US. (Information on ordering through MPS can be found here.)
UPDATE: More changes at Bloomsbury Academic: last month, they also announced the purchase of Applied Visual Arts Publishing - to be integrated into Bloomsbury Academic closer to the end of 2012.
