BRITISH publisher Bloomsbury Publishing posted a fall in full-year profit, but raised its dividend after a strong start to 2010. For the year ended 31 December, adjusted pre-tax profit was £7.71m, compared with £11.85m. Revenue fell 13 per cent to £87.22m, reflecting difficult trading conditions and tough comparison from last year when the paperback release of “Harry Potter and the Deathly Hallows” boosted sales.
