rolodexes

A rolodex is a desktop card file accessory used for storing and retrieving contact information. It typically consists of a cylindrical holder that rotates, allowing users to flip through a series of cards. Each card is usually pre-printed with spaces for a person's name, address, phone number, and other relevant details. The cards are held in place by a rotating spindle or a similar mechanism.

The rolodex was invented by Arnold D. Wagner in 1940 and patented in 1948. Its purpose was to provide a more organized and accessible way to manage contact lists compared to traditional address books or scattered notes. The name "rolodex" is a portmanteau of "roll," "locate," and "index."

These devices became popular in offices and homes throughout the latter half of the 20th century. They offered a tactile and convenient method for quickly finding and updating contact information. Many businesses relied on rolodexes for managing customer and client details before the widespread adoption of digital contact management systems.

With the advent of personal computers and digital devices, the rolodex has largely been superseded by electronic address books, contact management software, and cloud-based services. However, some individuals and businesses still prefer to use rolodexes for their simplicity and the physical organization they provide. Vintage rolodexes are also collected by enthusiasts.
