Citing Data

We request that users of CARD data cite the use of our data in their work.

Citation of data acquired from CARD acknowledges data contributors, and allows us to track the use and impact of our data, to more effectively report data distribution activity to funding agencies, and to assist other users who may contact us with questions about data that are referenced in publications.

Please note that we prefer that users include a citation in the references section of the publication. While we appreciate acknowledgement within the text of the publication, we are better able to track the use of our data sets if citations are included as references.

Appropriate citations are displayed on the catalog pages for many of our data sets. If you would like to cite data for which a citation is not provided, please contact us for help.

Further, we request that users send us one reprint of any published work for our library collection. This helps us to stay aware of how our data are being used by the user community and helps us to build our library collection.
