Read the given passage and answer the questions that follows:

A century ago, library Services were focused on architecture, physical workflow design, and urban planning. Planning the physical environment is still important, but more often than not, it serves as the backdrop for patrons operating in a world dominated by online information sources. The experience and preferences of library users are being affected by others. non-library services such as Amazon, Google, Facebook, Twitter, and social question-and-answer sites, etc., Library catalogs have long been the point of discovery and delivery of content. People want to find information quickly and conveniently, and they expect the interface to be familiar to them. Unfortunately, libraries have not consistently employed their usage data to fully mobilize discovery services in the same way as Google. Providing seamless points of access to the content people discover through other online services could be a point of distinction for libraries. A study concluded that access- not discovery-is the major challenge for today's information seekers, who may be better served by online library catalogs that improve delivery and provide more links to more online content. It is true that services like Google help people discover content more quickly and conveniently, but their search results often leave them wanting more. When faced with sifting through a lot of content, people want search engines that return information relevant to their search queries in order to minimize their need to evaluate the content.
