This chapter focuses on the philosophy, history, and development of the Oxford English Dictionary (OED) specifically. The creation of the OED was a monumental project, delivered alphabetically in fascicles (separate installments of a larger work, meant to be bound into a single volume when complete). The fascicles were released beginning in the 1880s and completed in 1928, followed by a supplement in 1933 to catch up with developments in the previous half century.
