ESS Open Archive does allow text and metadata mining. ESS Open Archive supports and participates in the Open Archives Initiative (OAI) and is a registered Open Archive Initiative Protocol for Metadata (OAI-PMH) data-provider. We also support the Center for Open Science SHARE Open API and the CrossRef Metadata API. All full-text content is available on the platform and can be crawled for text and data mining purposes. Standard crawlers are allowed. Bulk downloading is not supported. The terms applicable to the mining of preprints are determined by the authors’ selection of either a non-exclusive or Creative Commons license (CC-BY-NC-ND, CC-BY-NC, or CC-BY). Interested parties may limit searches to specific license types to meet their specific reuse needs.
