Pan Macmillan, a general book publisher in the UK, completed the acquisition of Harriman House, an independent publisher of finance, trading, and investment books. Financial terms were not disclosed. "Pan Macmillan is committed to expanding its non-fiction publishing. We launched Macmillan Business earlier this year and we see the acquisition of Harriman House as a significant step towards our ambition to be a leader in this area. Macmillan Business and Harriman House will remain distinct separate imprints within Pan Macmillan," Joanna Prior, Pan Macmillan CEO.
