The story

Ovid was founded in 1984 by Mark Nelson, who had developed an interface to MEDLINE, the world's largest and oldest medical database, produced by the US National Library of Medicine. The company at that time was known as Online Research Systems, a name Nelson chose to disguise the fact that he was the only employee of the company, operating out of an apartment in Spanish Harlem, New York City. The interface was designed to connect over the phone lines to mainframe computers of vendors, primarily BRS Online, which were running in-house search engines designed for Medline. However, fearing potential competition, these vendors shut off access for the interface. Nelson then decided to write his own Medline search engine, one of the first that was based on PCs.

Nelson had attempted, unsuccessfully, to obtain funding for the company. In order to fund operations, Nelson began building computers in his apartment, selling them along with the software. When the first product was released in 1988, the company changed its name to CD Plus. The product quickly became successful, fueled by innovations in search engine technology. Most importantly, Nelson had devised algorithms that encapsulated much of the complexity of Medline's lexicon, enabling end-users to achieve a high level of search precision without the need to master Medline's intricate taxonomy. The company's first Microsoft Windows interface to MEDLINE was named Ovid and released in 1992. Nelson, who had majored in English Literature and minored in classical languages, chose the name Ovid as a homage to the ancient Roman poet's most famous work, Metamorphoses. Several years later, Nelson started the Alpheios Project, non-profit software to facilitate the reading of ancient Greek and Latin.

The company's primary competitor continued to be BRS Online. CD-Plus gained significant market share from its competitor, and in 1994 acquired the company. Shortly after, CD-Plus went public at $6/share, and listed on NASDAQ. It then changed to its present name in 1995, reflecting the importance of its Ovid product.

In 1998, Nelson, who still retained the majority of Ovid shares, was wary of the market bubble that had been building for several years. He engaged Goldman Sachs to sell the company. Wolters Kluwer acquired the company in October, 1998, for $24.59/share.

Ovid continued to make inroads against its competitors. In 2001, Wolters Kluwer purchased the rival SilverPlatter company and merged it into Ovid during 2001 and early 2002.

Ovid introduced a new database search interface called OvidSP in 2007. This has replaced the Ovid Gateway interface, which was retired in February 2008, and the SilverPlatter interface, which was retired in January 2009.
