From the wealth of materials stored at the Palestine Exploration Fund: http://www.pef.org.uk/collections/, the following resources were examined over several visits:

• PEF minute books from 1936-1966.
• Uncatalogued slide collections.
• Reverend Robert Pitt Photographic Archives (nine boxes).
• BSAJ Minute Book (Kenyon Institute, formerly the British School of Archaeology in Jerusalem), from 1946-1958.

The Survey of Western Palestine: Memoirs – Topography, Orthography, Hydrography, and Archaeology, Volume II Sheets VIL-XVL Samaria (London: Palestine Exploration Quarterly, 1882), which serves as a historical memoir of the early record of the site is also now available online at: http://archive.org/search.php?query=Survey%20of%20Western%20Palestine2Ceramic
