Do you use arXiv content in application development or research?

« The arXiv team is gathering information on the use of arXiv the API and content in external applications and for research. We are doing so in order to inform the development of new arXiv APIs and to minimize disruption to current users of the arXiv API and arXiv content. If you use the arXiv API or otherwise access arXiv content in a programmatic way, we invite you to take a short survey. You may also sign up (via the survey) to provide input and receive news of changes as we proceed with API development. »
