I feel like libraries try to do too much all in the same space. The computer people bug the 'study-ers' with their typing, clicking, and audio. The printers are loud and disruptive. The desks are sprinkled throughout the aisles of books, wherever space could be found -- which makes it harder to navigate around to find the books you need. There's no need to be surrounded by books once you've gotten the one you need.
They're forcing 3 entirely different sets of people into the same space. If people are visiting with 3 different goals just separate the space according to those goals. Have a dedicated and separate computer lab, a dedicated room to rows and rows of books, and a dedicated room for studying -- with side rooms for group studying.
