Maybe 50 books about paperweights have been written in the last 80 years. The authors reflected the understanding and extent of knowledge at the time of writing: further studies and research over the last 30 years have shown that there are significant errors and omissions in many of these earlier books - and even in some very recent ones! The older books make interesting reading, but they are not always reliable.
There are quite a lot of useful books, so where do you start ? Perhaps with a relatively low cost, general guide such as Miller's -or maybe a book that focuses on a specific maker you like, such as Perthshire Paperweights. There are several good books that look at paperweights from around the world. Here are some that we have found useful.
