"Each fall YBP publishes a report on price and output for new books published during our prior fiscal year. The data encompasses all new titles treated on the Approval Plan programs of YBP and of Lindsay & Croft, YBP's division in the United Kingdom, two offices which regularly profile, with book-in-hand, well over 65,000 distinct new titles annually. Since our Approval Plan programs are expressly designed to serve academic libraries, our data, which we have reported in a consistent way for over a dozen years, is a useful index to English-language publishing trends for scholarly, professional, and scientific books."
