Well done for the time and effort in creating such a list.
Personally, I'm interested in paperweights, and my use of the list is to try finding leads in identifying signed/marked weights.
I would recommend Andy Dohan's Dictionary of Paperweight Signature Canes (latest version on CD - as covered in a message in the Market Place
) Andy's CD covers over 360 names, companies etc., has 1650 colour images and links the actual signatures with over 360 makers. That goes a long way to sorting out the list of possibles for almost all known paperweight makers - and in the CD version, lots of bead makers are listed, too, so that helps to separate the different categories.
Your list has 447 entries which shows that you have included over 80 names that are not in Andy's CD book and may, therefore be unconnected with paperweights / marbles. There are also names in Andy's CD book that are not in your list, including the famous people from the start of paperweight making in Murano as well as some names from more modern times in Murano.
Frank mentioned some of the factors that might be needed to help maintain and use such a list. I would suggest that country would be useful, too. Are you including names on labels in the same way as signatures? As just one example, "Scotia of Scotland" is mentioned, but that was (I think) just a trading name used by William Manson at one time. So perhaps there should be some form of link between "Manson" and "Scotia" within the list, otherwise, people new to paperweights might think that they are separate makers. That sort of linking would apply to many of the names but it would also start to make the full list quite complex, hence, as Frank says, a need for some type of moderating would be required.
