Accessing corpora
Our corpora are available in soft copy. To access the corpora, you need to agree to the conditions of use, as detailed below.
Licenses, copyright, and user agreements
In order to use any of the corpora, you need to register. By registering, you agree to inform yourself of and observe all access and use restrictions for the corpora, and to not copy them or large chunks of them to non-Stanford machines. These rules also apply to corpora that can be freely downloaded from the web. Be aware that by not following these rules you violate federal copyright law (in several countries, depending on the corpus).
We urge corpus users to be responsible about reporting the source of information obtained in corpus searches. At a minimum, the corpus creator should be identified and bibliographic information on the source document should be included with any citation.
How to register
General use agreement
In order to register, please send an email to Jinyoung Jo. You will receive a copy of the user agreement, which you must sign and return. Once received, you will be granted access to the requested corpus.
Corpora with special access restrictions
Some corpora require a special signed agreement from you. Before you can be given access to those corpora, you need to hand in the signed agreement. Some corpora are subject to other kind of limitations — for example a maximum number of simultaneously registers users. The restricted corpora and a link to their user license template (if applicable) are listed below.
