Melissa A. Brown and Kenneth D. Crews have self-archived "Control of Museum Art Images: The Reach and Limits of Copyright and Licensing" in SSRN.
Here's an excerpt:
Many museums and art libraries have digitized their collections of artworks. Digital imaging capabilities represent a significant development in the academic study of art, and they enhance the availability of art images to the public at large. The possible uses of these images are likewise broad. Many of these uses, however, are potentially defined by copyright law or by license agreements imposed by some museums and libraries that attempt to define allowable uses. Often, these terms and conditions will mean that an online image is not truly available for many purposes, including publication in the context of research or simple enjoyment. Not only do these terms and conditions restrict uses, they also have dubious legal standing after the Bridgeman case. This paper examines the legal premises behind claiming copyright in art images and the ability to impose license restrictions on their use.
This paper is one outcome of a study of museum licensing practices funded by The Samuel H. Kress Foundation. This paper is principally an introduction to the relevant law in the United States and a survey of examples of museum licenses. The project is in its early stages, with the expectation that later studies will expand on this introduction and provide greater analysis of the legal complications of copyright, the public domain, and the reach of license agreements as a means for controlling the use of artwork and potentially any other works, whether or not they fall within the scope of copyright protection.
