The following set of principles is intended to guide librarians in negotiating with vendors and in considering text and data mining (TDM)-related acquisitions.

• Availability. Resources acquired for the purposes of TDM research should be available indefinitely to the institutional community as a whole.

• Privacy. TDM platforms, tools, and data should be available to institutions and researchers without the requirement of identifying individual researchers or research projects.

• Portability. The mode of delivery for source data to be utilized in TDM research should be as portable as possible, limited only as necessary.

• Accessibility. To the extent that a specific platform is required for TDM, that platform will be made accessible to researchers with a broad range of abilities.

• Reproducibility. Research outputs that utilize TDM tools, data, or platforms should be reproducible and transparent.

• Sustainability. TDM access should not involve unsustainable expenditures for the institution or the passing of costs on to researchers.

• Collaboration. TDM tools, resources, and products should facilitate cross-institutional collaboration.
