I think the book referred to on e-bay would be Catalogue Raisonne de L'oevre de verre by Felix Marcilhac. It seems to be the standard source that Lalique collectors refer to. I checked an e-bay item (a glass elephant) and the page number matched up to this source. According to Robert Prescott-Walker's book Collecting Lalique Glass, this is the one book that is considered essential for Lalique collectors. You might also look at the enclosed bibliography on Lalique for other sources.
If you want to order this Marcilhac catalog, go to Amazon or another on-line seller and you should see some used copies.
