Discussion, whether in terms of collection building or of research instruction, of print “versus” online resources is outdated and fruitless if that discussion doesn’t seek to clarify and resolve the relative existing and potential qualities of each format in terms of permanence, stability, and “structured” vs. “random” accessibility.
The classic visual impression of a library is an image of books and periodical volumes printed in ink on paper, bound together, and arranged on ranks of shelving. Depending, perhaps, on attitude of the one crafting that image, these imagined shelves might well be either an image of picturesque rows of beautifully bound classics or a vision of of dusty, dark, and utterly impenetrable frustration. But of course all libraries, and particularly academic research libraries, are also deeply engaged with non-tangible resources. Not “books,” but instead the mass of content that we variously refer to as “digital,” “electronic,” or “online” resources. Stuff that is provided to end users, usually via the Internet, out of networked computerized storage.
