Query: Antique Clocks Identification and Price Guide CD-ROM and Internet Resource

I was surprised when the CD-ROM arrived and I opened it to find only a pdf file.It was difficult to read. The most annoying feature was NO INDEX. Without the index the CD-ROM is vertually useless as an identification guide. Little information on the history of the companies. Little information about Europen clocksThe Internet Resource is limited.Do not waste your money on the guide.
