Free index of over 100 million published journal articles


The General Index provides words and phrases from millions of scientific research articles – a massive resource for researchers for free.

What there is to know:

  • On October 7, Public Resource, a nonprofit organization, released the General Index, a repository of 355 billion words and phrases related to scientific articles in which those words appear.

  • While it includes articles that are behind pay walls, the index is no more than five words per article, so it respects publishers’ copyright restrictions.

  • Creator Carl Malamud aims to enable researchers to conduct large-scale analyzes without being limited to open access articles or those to which they have access.

  • The index is considered by some to be a major development in text mining. It allows scientists to build more extensive databases on specialized topics in scientific literature.

  • A search engine was not created with the index, but Malamud hopes that if anyone designs one, they will make it accessible to everyone.
