I agree with the looking around and learning, but if you've something already in hand and want to try a little searching yourself here's some general suggestions.
1/ Take some simple keywords and run an ebay search with and without the description include. Turn to Google and run the same searches using Google images which is a tab right above the search bar. If this turns up nothing even remotely similar then turn to the discussion boards
2/ If these searches turn up something even remotely similar follow the paths utilizing the searches with the new names or dates you might gleen from the earlier searches.
3/ about this time remember that not every item listed on the internet is ID'd correctly
so you might end up barking up the wrong tree but don't be discouraged as you learn you'll be able to discount the wrongly id'd items faster and easier.
4/ as you go purchase books, these although they do contain mistakes here and there, will have a lot less mistakes and guide you a little better plus by browsing the books you can get a feel for the shapes, patterns and general feel of each type of glass you're interested in.
5/ If you think you find a correct ID check with us anyways
cause as I said there are mistakes and mis id'd stuff out there and until you're more versed in the ways of the glass world it might be good to double check what you find out.
Hope this helps, bad spelling and all
