From the Official Announcement:
The IEEE Xplore digital library, one of the world’s largest collections of high quality technical literature in engineering and technology, recently added its three millionth document to its vast digital library. “Protecting Smart Grid Automation Systems Against Cyberattacks,” which appears in the current issue of IEEE Transactions on Smart Grid, reflects a sample of the diverse technical disciplines represented in the collection. It took five years to grow the IEEE Xplore repository from one million to two million documents; and less than two-and-a-half years to reach this latest milestone.
