Earlier this year, we completed work on a massive renovation for our book viewer. The new viewer for books and other media uses scalable software and protocols, such as MongoDB and JSON, to deliver book information and book images efficiently. The new infrastructure also allows us to publish books more quickly, with less human intervention. We reduced our time-to-publish for Arabic Collections Online from 2 months for 200 books to about one week. This dramatic improvement has allowed us to scale our publication schedule from 200 books every other month to 400 books every month. As of this writing, ACO has almost 3,000 books, double the amount that we had earlier this year.
