Pleased to have reached the end of this task, much more work than I had expected, 1,400 entries have been completely reviewed and the abstracts extended with details of contents allowing search by glass types, companies etc. Bear in mind such entries are not there for every book. Perhaps ... you can help by sending me tables of contents and list of companies mentioned etc.
About 400 titles have been added, completing many series of books and journals. Journals have had contents added where available. Almost all original editions and printings/editions located and noted in the abstract.
I am very pleased with result and used it to locate references to Bristol glass in answer on this board the other day.
Do read the notice
here before using. There is a technical problem that makes the
All Titles option not browsable - I have to wait for the developer to finish his thesis unless a friendly PHP programmer wants to help him resolve the minor bugs

Anyway... try it out and report back here with your opinions please.
And a big thanks to those of you who helped with some of the references.
Authors and publishers are asked to provide any of their titles that are missing.
