Hello, I guess, being an American, I refer to Austro Hungarian and Czech because to me it indicates not only a region, but also seems to indicate a time frame. My understanding is that the "Austro-Hungarian Empire ceased to be at the end of WWI and Czechoslovakia was born. They are terms I started using many years ago, and being an old dog, it is most likely that is is quite hard to teach me new tricks!! But, Bohemian glass it is!!
I wish I could give you a few easy references, but as far as references or books on Kralik or Pallme-Koenig etc, I do not really have any. I have used the internet for research through the years, as I was around when Al Gore invented it (an American joke I am afraid). I have accumulated lots and lots of internet sites of collectors, archives, articles and dealers I have grown to trust. I use this library of websites as reference. Through the years I have also made internet connections with a handful of respected authorities on Bohemian

glass that I am lucky enough to email images to if I have doubts or questions. Most of the info available on the lesser documented houses such has Kralik, Rhindskopf, Pallme-Koenig etc is scattered about in bits and pieces. I have a very large folder of bookmarks on my internet browser that are specifically related to glass, and I add a new one at least a couple of times a week. My experience, and I am certainly not an expert, is that much of the attributions can more effectively be done with a study of decors, small characteristics such as the number of folds on the mouth of a vase, and the primary shapes used by the different houses. In most cases a reasonably accurate attribution can be made based on a knowledge of those. This opinion is echoed on a few websites I use. It never ceases to amaze me the number of changes in attributions that occur though out the study of this early glass. What was once thought to be a piece by one house a number of years ago, is later attributed to another house based on new information that comes to light. In many cases these changes occur based on new knowledge derived from comparative studies of shapes and decors. I love the search for great pieces of glass, but I love the search for the knowledge about it at least as much if not more. To sum it up.... I am a complete internet junkie when it comes to glass!!!
