British Library 
Very large collection formed through copyright-deposit, gift, and purchase. While the British Library has not deliberately built up a T. E. Lawrence special-collection, it has accumulated very significant holdings.

Printed books.
Manuscripts. The on-line manuscripts catalogue is now accessible via the web.
India Office Library.

Manuscripts:

• Early typescript draft of The Mint (1927-8) with extensive manuscript re-working (bequeathed by Charlotte Shaw).

• Later fair-copy  typescript of The Mint (bequeathed by Charlotte Shaw).

• Manuscript translation (1928-31) of Homer's Odyssey (bequeathed by Charlotte Shaw).

Letters by Lawrence:

Documents

• The archives of the India Office, holding important papers relevant to Lawrence's wartime service in the Middle East and later RAF service in India.

• Relevant papers of Lawrence's friends, including C. F. Bell, Sydney Cockerell, Bernard Shaw, and Charlotte Shaw. The last includes photographs and some press-clippings.

Printed books:

• Two of the six extant copies of the 1922 Oxford Times proof of Seven Pillars of Wisdom, with corrections and annotations by Lawrence and others. 

• A copy of the 1926 Subscribers' edition of Seven Pillars of Wisdom.

• All six Corvinus Press T. E. Lawrence titles.

• Almost all English first editions of printed works by and about Lawrence.

Through its copyright-deposit status, the British Library is one of the outstanding UK research libraries, holding a very wide range of printed background material such as autobiographies by Lawrence's friends and acquaintances.
