Blended Library - neue Zugangswege zu den Inhalten wissenschaftlicher und öffentlicher Bibliotheken.

The article discusses new ways to access library collections based on two joint initiative projects with scientific and public libraries. In the beginning of each scientific initiative, we conducted a number of empirical studies in order to gain valuable insights about users' patterns when accessing library collections. In detail, we distinguish between intuitive, collaborative, transparent, and contextual access. These four qualities served as a basis for the development of interactive systems. In this article, we discuss how we derived these four qualities based on our empirical studies and explain their implementation in the inquiring systems 'Blended Shelf', 'TwisterSearch', 'Tiefenrausch', and 'Expedition'. Finally, we elaborate on insights and experiences gained through the development of our systems, especially how our work feeds back and further informs the four ways to access library collections.
