In preparation for the work ahead, Murray built a corrugated-iron shed in the grounds of Mill Hill School, called the Scriptorium, to house his small team of assistants as well as the flood of slips (bearing quotations illustrating the use of words to be defined in the dictionary) which started to flow in as a result of his appeal. As work continued on the early part of the dictionary, Murray gave up his job as a teacher and became a full-time lexicographer.
