There are three main sources of information on the writing of Seven Pillars of Wisdom from Lawrence's own pen, all in part contradictory:
Notes - Some notes on the writing of the Seven Pillars of Wisdom by T E Shaw is the title of a four-page printed leaflet issued with the subscribers' edition, and these notes were incorporated in A W Lawrence's preface to subsequent trade editions.
History - History of Seven Pillars is a document in Lawrence's own hand, dating from January 1927, and therefore written shortly after the subscribers' edition was published. This apparent aide-memoire is closely written on one side of a foolscap sheet and both sides of a half sheet. The manuscript was brought to light in the early 1960s, and is now in the collection of the Humanities Research Centre of the University of Texas.
Bod ms - The manuscript of the third draft of the book, given by Lawrence to the Bodleian Library, Oxford, contains a list of dates relating to the various stages of writing.
