This excellent site presents the Great Isaiah Scroll of the Qumran community, showing a photographic plate of each column of the scroll with a line-by-line translation and a detailed analysis of physical characteristics and textual variants.
My comments on each page about the scroll are meant to help you to get to know about the scroll and the technical differences between it and the received text. It is not meant to be a commentary on the book of Isaiah. If you can read Hebrew it will enhance your study of the scroll greatly, but it is not necessary to read Hebrew to gain some insight into what the Scroll is like and to understand its importance…. The critical comments are meant for beginning and intermediate students. Advanced students will also find things of interest on these pages, but this is not to be considered a “scholar’s” work.
A good place to start is the introductory page, which describes the physical condition of the scroll and the editorial markings and (for those who know some Hebrew) the peculiarities of the language.
I found the site via PaleoJudaica, “a blog on ancient (‘paleo-’) Judaism (‘Judaica’) and its historical and literary context from roughly the beginning of the Second Temple period (late 500s B.C.E.) to the rise of Islam (early 600s C.E.),” which has all manner of interesting information. It’s run by Dr. James R. Davila (“please call me Jim”), a Lecturer in Early Jewish Studies at the University of St. Andrews in Scotland. Well done, Jim!
