All you need to get started is an individual JSTOR account (which you can create for on our registration page). Once you are logged in you can, you can obtain the following data: 

• Metadata (with references) and word counts, bi-grams, and tri-grams for up to 25,000 articles at a time.
• Technical specifications, sample datasets, and detailed instructions all in one place. 

To obtain OCR files for journals, reports, pamphlets, and datasets beyond 25,000 documents, please complete the following form so our team can evaluate your request: DFR Custom Request Form.
