In two cases, exchanges between letter writers and authors were too long (and technical) to print in our letters column. Therefore we have posted them on our website at www.biblicalarchaeology.org/responses.

One involves the Archaeological Views column titled “The Great Tekhelet Debate—Blue or Purple?” by Baruch and Judy Taubes Sterman (BAR 39:05), which is criticized in a letter by Professor Zvi C. Koren, director of the Edelstein Center for the Analysis of Ancient Artifacts at the Shenker College of Engineering and Design in Ramat Gan, Israel, to which the Stermans have replied.

The other involves a letter by Bill Schlegel that is critical of Steven Collins’s article on “Where Is Sodom? The Case for Tall el-Hammam” (BAR 39:02), to which Professor Collins has replied.

Finally, we post a letter from Amihai Sneh, Ram Weinberger, Eyal Shalev of the Geological Survey of Israel, critical of an article by BAR editor Hershel Shanks on Hezekiah’s Tunnel (“Will King Hezekiah Be Dislodged from His Tunnel?BAR, 39:05).
