Tee hee... I'm also ssssoooooo in love with Czech glass.
The best reference sites for Czech glass of all types would include Jindrich Parik's "Ceskoslovenske Sklo" where you can peruse the CGR, factory catalogues, get information about designers, glassworks, etc. It's my favorite site: http://www.cs-sklo.cz/
For a quick and easy look into Czech pressed glass items, see http://sklo-union-glass.com/
. It's got great photographs which can help you identify your glass, plus Frank has taken the time to provide references.
Emil has also got a blog about Czech glass with wonderful examples of Czech items in his album: http://www.bohemiaglas.se/page1.html
Then, of course, there are all the other members' albums which may also offer IDs, or at least something to drool over.
When it comes to literature, I would strongly
recommend Marcus Newhall's "Sklo Union: Art Before Industry" (see the marketplace -- the book is not longer readily available in bookshops, but our Anne has got copies available on ebay). Not only is it an attractive book, but Marcus Newhall offers a cd database with sklo union catalogues not available elsewhere. It's a must have if you're into Czech pressed glass.
I wish you happy collecting! And please feel free to show off your finds, even if you know what they are.
