The Isaac Rosenberg Collection archival holdings
The manuscripts that survived Isaac Rosenberg's death in April 1918 passed mostly into the possession of his sister, Annie. In 1953 Annie passed most of these papers onto her literary executors, Patric Dickenson and Ian Parsons, the literary executor of the Gordon Bottomley estate also inherited further Rosenberg material. Together, in 1979, both estates combined their their collections and donated the manuscripts to the Department of Documents at the Imperial War Museum.
The First World War Poetry Digital Archive has digitised a significant selection of the holdings at the IWM, along with holdings of correspondance at The British Library and The Berg Collection at New York Public Library. More than with most poets the manuscripts of Isaac Rosenberg tell us important information about the conditions that the poet worked under, especially in France. Paper was in short supply and Rosenberg wrote on any scraps he could find, almost all of the poetry he produced between June 1916 and April 1918 was written in or close to the front line. His paper became wet, torn, and stained with mud. The materiality of the manuscripts tells us a lot about Rosenberg's life.
