Beatrice Egerton is an author about whom little public information is currently available. Her name appears in bibliographic records as "Egerton, Beatrice," and her Chinese name is provisionally rendered as Bi'atilisi Aijiedun. Existing sources do not record her nationality, dates of birth and death, education, or writing career, so it is difficult to sketch the outlines of her life. Only one work by her is held in the collection, Lippa, and this is the main basis for understanding her creative profile. The existence of this work suggests that she wrote narrative fiction, and that it was catalogued and has been preserved. Because information on genre, editions, and reviews is lacking, it is not possible to determine the content, stylistic features, or readership of Lippa. Any introduction to her must therefore remain at the level of a recorded work, and fuller information awaits the discovery of new sources.
