The London Book Fair has contacted exhibitors and rights center table-holders with a “thank you”/”loyalty” package in consideration of the “unprecedented circumstances brought about by the volcanic ash in Iceland.” Customers from the 2010 show are being offered a 30 percent discount on the published 2011 prices for exhibition space and rights center tables, “in recognition of the disruption to the show, and to our 40th birthday in 2011.” Additionally, any pre-registered international visitor in 2010 who was unable to attend and did not transfer their ticket to someone else can attend for free next year.
