There are no definitive sources of continuously updated lists of retired Fenton art glass lamps, and even collectors and antiques dealers appear to be at the mercy of hearsay. Precisely for this reason, the websites of collectors, antiques dealers, antiques appraisers and online auction sites, such as eBay.com, are potential sources of information about retired Fenton art glass lamps.
S&K Collectibles, for instance, occasionally lists limited edition Fenton art glass lamps on its website, SandKCollectibles.com. While limited editions are not necessarily retired, their limited run means there are only so many produced and in circulation, which places their value and rarity on a par with retired lamps.
Old Fenton art glass catalogs are another potential source of information about retired Fenton lamps. Many of the old catalogs are actual pages on FentonArtGlass.com, and some of the catalogs include lists of authorized Fenton art glass dealers throughout the United States.
