This article was from February 2018, so I don’t know if this exhibit is still on display.  Has anyone seen it, by chance?  Makes me glad they are trying to preserve the Gregg collection online.  I quoted the relevant shorthand part of the article below:

From typewriters to touch screens, a spotlight on the past

The most significant part of the display is the vast collection of shorthand material collected by Louis A. Leslie, an American author whose work with Gregg shorthand influenced many academic institutions.

Shorthand, which consists of a series of abbreviations and symbols representing letters and phrases, was taught in colleges and universities for decades before its popularity faded. Most American institutions utilized the Gregg shorthand system created by John R. Gregg.

According to Congleton, with thousands of items catalogued in the collection, Rider’s display rivals the New York Public Library’s collection of shorthand material for being the largest collection in the world.

“This is probably our most famous special collection,” said Telonidis. “It consists of a lot of different works in shorthand and many of them are instruction manuals. There are many, many different types of shorthand and the main ones are represented here.”

Rider acquired the collection because of their relationship with John Robert Gregg Fund of the Community Trust, who entrusted them with conserving the items.

“A lot of the materials came to us in the late ’80s and ’90s because Leslie was the vice president of the Gregg Shorthand Company,” said Congleton. “He collected shorthand material throughout his life and, after he died, the foundation decided to grant us the collection.”

Now, the Moore archivists are preserving the massive collection online.

“We have 365 shorthand works digitized and on our website,” said Telonidis. “There’s a lot more, so we’re still working on adding to it.”

Both Telonidis and Congleton feel the exhibit will help the Rider community trace the roots of technology in a fun and efficient way.
