Is Prabook free or proprietary source?

Part of Prabook’s content is posted by its users and invited professionals who help enrich the database using the information from publicly available sources. Such content is free and open to everyone.

At the same time, the company has discovered the existence of a large number of nondigitized biographical dictionaries that were left in obscurity with their information no longer serving humanity. To bring them back to life, the Prabook team has developed a technology that helps extract, refine, parse and then merge information into unique biographical articles.

This method makes up the majority of Prabook’s content with two and a half million articles that are available only to subscribers.

Thus, Prabook helps preserve rare archival information that we are pleased to provide for our users.
