Back before the days of electronic devices for keeping track of business contacts, rotating card file devices such as Rollodex and these Visidex were popular.

These three Visidex card files from W. G. Goetz and Sons were slavaged from somewhere by Melbourne based documentray photographer Warren Kirk and donated to W. G. Goetz History.  Thanks Warren!

The date is unknown, but as the phone numbers have only 7 digits, they probably date up to the mid 1990s, when the 8th digit was introduced, but many card entries appear to be much older.

The three Visidex files contain hundreds of contact names, addresses and phone numbers, many from large comapnies such as BHP, CIG Gasses, Containers Limited, Gadsen, Edgell, Nestlé, GMH and many others.

These examples are from RVB Products (see the RVB entry regarding their involvement with Goetz) and Ansett Technologies.
