A Rolodex is a rotating card file device used to store a contact list. Its name, a portmanteau of the words "rolling" and "index", has become somewhat genericized for any personal organizer performing this function, or as a metonym for a total accumulation of business contacts. In this usage, it has generally come to describe an effect or characteristic of the small-world network{{Cite web |last1=Brügemann |first1=Björn |last2=Gautier |first2=P. |last3=Menzio |first3=G. |date=2017 |title=Rolodex Game in Networks |url=https://web-facstaff.sas.upenn.edu/~gmenzio/linkies/Rolodex.pdf |access-date=2022-08-21 |website=web-facstaff.sas.upenn.edu |s2cid=212425470 |language=en}} of a business's investors,{{Cite journal |last=Hui |first=Pamsy P. |date=2004-08-01 |title=The rolodex paradox: effects of ties to and via venture capitalists on startup survival and commercial success. |url=https://journals.aom.org/doi/abs/10.5465/ambpp.2004.13857681 |journal=Academy of Management Proceedings |volume=2004 |issue=1 |pages=E1–E6 |doi=10.5465/ambpp.2004.13857681 |issn=0065-0668}} board of directors,{{Cite journal |last=Nguyen |first=Bang Dang |date=2012-02-01 |title=Does the Rolodex Matter?

History

The Rolodex was invented in 1956 by Danish engineer Hildaur Neilsen, the chief engineer of Arnold Neustadter's company Zephyr American, a stationery manufacturer in New York.{{cite patent |country=US |number=2731966A |status=patent |title=Rotary card-filing device |gdate=1956-01-24 |fdate=1953-03-26 |inventor1-first=Hildaur L. |inventor1-last=Neilsen |assign1=Zephyr American Corporation |url=https://patents.google.com/patent/US2731966}}.

}} it was an improvement to an earlier design called the Wheeldex. Zephyr American also invented, manufactured and sold the Autodex, a spring-operated phone directory that automatically opened to the selected letter; Swivodex, an inkwell that did not spill; Punchodex, a paper hole puncher; and Clipodex, an office aid that attached to a stenographer's knee.{{cite web

Rolodex also marketed non-rotary (linear) tub-like card-file systems using the same cards (size and notches) as the rotary files.

Neustadter retired and sold out to a larger firm in 1970.{{Cite web |last1=Lasker |first1=David |date=1990-01-28 |title=ICONS: Rolodex: A Rotary File Comes Full Circle |url=https://www.latimes.com/archives/la-xpm-1990-01-28-tm-1087-story.html |access-date=2022-08-21 |website=Los Angeles Times |language=en-US}} The Rolodex remained popular throughout the 1980s, and individual Rolodexes containing a large amount of information were considered valuable, and lawsuits were filed by companies against employees who attempted to take their Rolodex with them when leaving the company. A 1985 episode of the detective TV series Moonlighting involved a stolen Rolodex being ransomed for $50,000 — a figure reflecting the value of the data it contained. The system fell out of widespread use in the 2000s, as digital storage became the norm. However, Rolodex cards are still produced, and have a niche usership.{{Cite web|url=https://gizmodo.com/the-life-and-death-of-the-rolodex-5497511|title=The Life and Death of the Rolodex|first=Anna Jane|last=Grossman|date=March 20, 2010|website=Gizmodo}}
