A charity that represents the voice of literature in the UK, the RSL has about 600 Fellows, elected from among the best writers in any genre currently at work. Additionally, Honorary Fellows are chosen from those who have made a significant contribution to the advancement of literature, including publishers, agents, librarians, booksellers or producers. The society is a cultural tenant at London's Somerset House.
