I'll move to you, Mr. Ramsankar, and ask about the movement from print to digital and online resources that you were talking about. Perhaps all of you mentioned that.
Could you expand on that? What's the proportion of online versus print material used in classrooms, if you know, and how might this affect authors or producers of that material? How is that factored into your purchases? Are teachers going online and looking for free material specifically because it's free?
