Laurel,
I, too, have been involved in an on-going project focused on The Science Center's inkwell and ink bottle collection.  Here are some of the resources I've found:
- A. C. Revi, American Pressed Glass and Figural Bottles
- www.antiquebottles.com
- www.fohbc.com (Federation of Historic Bottle Collectors)
- www.glass.co.nz (glass museum)
- Henry Cleveland, Bottle Pricing Gd.
-Julian Harrison Toulouse, Bottle Makers and Their Marks
- Cecil Munsey, Illustrated GT Collecting Bottles (out-of-print)
-www.antiquebotl.com
-Kovels' Bottle Price List
-Carlo Sellari, The Illus. Price Gd. of Antique Bottles
- Donald Goodell, The American Bottle Collector's Price Gd. to Historical Flasks, Pontils, Bitters, Mineral Waters, Inks & Sodas

Hope this helps.  Information is limited, but you can identify makers.
