Copyright in the digital images of the manuscripts, created by the Israel Museum and displayed on this site, is held by the Israel Museum. Reproducing these digital images in any manner other than for research or private study requires prior permission or licensing.
The Wikipedia crowd are (rightly) griping about this; we've long held that faithful digital reproductions of 2D copyrighted work simply inherit the copyright of the original. It's sad to see such a nice thing marred by a silly approach to copyright.
As if they are scared people are going to, what, misuse the material and make a fortune out of it?
