A national digital library should be universal and offer popular content—both books and multimedia. The library should serve not just the needs of academics, researchers, and lovers of high culture, the country at large, with the promotion of literacy and knowledge of all kinds—including the sciences and useful arts.
In fact, the system should offer everything such as textbooks, carefully vetted scholarly papers, user-contributed photographs, local oral histories, and multimedia job-training materials, as well as other directly practical content. We mustn’t neglect digital textbooks, multimedia, and other how-to content for students, small-business people, factory workers, and others. Those are the kinds of materials that can help our country create the wealth and economic growth we keep hearing so much about. Libraries are notable for aiding to realize ambitions that can lead to gainful or more-gainful employment; digital-library collections should reflect that interest in self-improvement and other life-changers.
