About the Bibliomaniacs

The Bibliomaniacs are the youngest antiquarian booksellers in the world. We meet every Thursday to discuss recent book sales, our next catalogues and to discover more about the history of literature, books and printing. Founded in 2009 by Jonathan Cooper, Deputy Headmaster (Academic) at Papplewick School (former member of the book department at Sotheby’s) and Lucas Marsden-Smedley, a former pupil. We have visited the British Library, the Bodleian Library, Henry Sotheran, the oldest second-hand bookshop in the world, Sotheby’s and Bloomsbury auction houses, the Winchester and Eton College Libraries and the Royal Library at Windsor Castle. We have also travelled to New York City. The Bibliomaniacs feel honoured to have been elected members of the PBFA in 2016, and have exhibited at the London International Premier Book Fair in 2016, 2017, 2018, 2019, 2023 and 2025.
