Imareal is a wonderful site for the research of medieval paintings and many other topics covered in a set of online databases. This is all supported by the "Institut für Realienkunde des Mittelalters und der frühen Neuzeit" in Krems, Austria. This institute is the home of over a dozen people financed by the Austrian Academy of Sciences. The said Austrian Academy is about to lose a big part of its money and thinks about killing 300 - 450 full time jobs including the ones in Krems. There is an online petition attempting to prevent this desaster with over 13000 signatures as of this writing.
