“Long-term preservation of scholarly literature in digital form is crucial to the mission of academic libraries. Researchers in all disciplines depend on their libraries to ensure the safekeeping of the scholarly record, underpinning responsible research methods. The CLOCKSS Archive is a unique community where libraries can take united action to collaborate with publishers and with each other to ensure that the digital research is preserved now for the sake of future scholarship.”
