Opportunities for Data Exchange has released Best Practices for Citability of Data and Evolving Roles in Scholarly Communication.
Here's an excerpt:
This report sets out the current thinking on data citation best practice and presents the results of a survey of librarians asking how new support roles could and should be developed. The findings presented here build on the extensive desk research carried out for the report "Integration of Data and Publication" (Reilly, Schallier, Schrimpf, Smit, & Wilkinson, Sept 2011), which identified that data citation was an area of opportunity for both researchers and libraries. That report also recounted the findings of a workshop held at the LIBER 2011 Conference in Barcelona. . . .This previous work is supported here with further information gathered through extensive desk research, structured interviews and an online survey of LIBER members to explore best practice in data citation and evolving support roles for libraries.
