This chart shows the total number of new print books made available during each of the past two academic years, along with the aggregate circulation during the same academic year. It’s interesting to note that despite many fewer print books purchased in 2013-2014 (due to both big ebook purchases and declining budgets), the ratios of circulation per book and percentage of books having circulated at least once remained relatively constant.
