In addition to some 4 million printed books held by the Freie Universität Berlin libraries, more and more e-books are being acquired. At approximately 600,000 (in 2016), e-books now make up more than an eighth of the total holdings. Be sure to include them in your literature searches.
You can filter books from your search in the library portal Primo by selecting the "Books" facet. In order to find e-books, select the "Books" and "Full texts online" facets combined.
Within the Primo search scope, you will find FU-licensed e-book as well as freely accessible books listed in the Primo mega-index; this includes sources contained in institutional repositories or open-access platforms, digitized sources provided by libraries etc. For parts of the book inventory, even chapters will show up in result lists, depending on the metadata in the Primo mega-index.
Within the FU Catalog scope, you will find FU-licensed e-books as well as print books. Chapters and articles cannot be searched.
The University Library is a lending library: Over 90 percent of holdings can be taken out (see: Circulation).
