The Irish Book Lover ranks as the longest-lasting of all twentieth-century Irish literary journals, with a run of 227 issues published under the editorships of John S. Crone (1909-25), Séamus Ó Casaide (1928-1930) and Colm Ó Lochlainn (1930-57). As a bibliographical and reviewing journal rather than a forum for commentary, poetry or fiction, it is less often consulted than literary journals such as the Irish Review or The Bell but nevertheless illustrates with great clarity some of the key changes in modern Irish culture and society between 1909 and 1957. While offering a unique source of information on older, antiquarian books in Ireland, The Irish Book Lover throws open a window on the attitude of the contemporary intelligentsia to works such as James Joyce's Portrait of the Artist and W. B. Yeats's responsibilities, the novels of Liam O'Flaherty and Kate O'Brien or those of less-remembered writers of the day such as Temple Lane and Mrs. Thomas Concannon. Though superseded by a variety of reviewing organs, it gives an inspiring example to Irish book lovers in our own time. The Princess Grace Irish Library has compiled a sampler of the journal here, together with an index of the entire series. The present volume also contains an introductory lecture given by Dr. Nicholas Allen at the "Irish Book Lover" Symposium which was held in Monaco to commemorate the journal. The symposium was also afforded a planned opportunity to survey existing resources for Irish literary history in the company of fifteen Irish publishers, librarians, teachers, critics and--last but not least--owners of Irish-studies websites. The present volume is mirrored on the PGIL EIRData website, giving access to a body of digitized text that embraces a wider selection of the long-running journal together with an electronic index of its pages. This new departure for Irish studies has been conducted by Dr. Bruce Stewart under the terms of a contract between the Ireland Fund of Monaco to the University of Ulster under the aegis of the Princess Grace Irish Library (Monaco).
