hi - collecting pieces because you like them is probably the best way to collect, at least you shouldn't get bored with them for a very long time. There is a lot of good information offered by the guys here, many of whom are very knowledgeable, but I would still recommend buying just a few quality books from which you will also learn much ................ for British glass, generally, spanning C19 and C20 I'd suggest both of the Hajdamach offerings - then, depending on your personal taste perhaps Bickerton for drinking glasses from C18 and C19, plus others that may appeal. These can be found on Abe, for example, and purchased as pre-owned. Sadly, there isn't anything specific on British cut glass, though you will find odd chapters or sections in some of the better books.
