The ostraca were discovered by James Leslie Starkey in January–February 1935, during the third campaign of the Wellcome excavations. They were published in 1938 by Harry Torczyner (name later changed to Naftali Herz Tur-Sinai) and have been much studied since then. Seventeen of them are currently located in the British Museum in London,[1] a smaller number (including Letter 6) are on permanent display at the Rockefeller Museum in East Jerusalem.[2] The primary inscriptions are known as KAI 192–199.
