Dear colleagues, A selection of approximately 26,000 Springer e-books with publication date 2015-2017 is available until September 2018. The collection includes approximately 16,300 scientific-technological titles, including textbooks, handbooks, contributed volumes, proceedings, etc. The titles are searchable directly from the SpringerLink page, or you can choose a discipline of interest, remembering to deselect the "Include Preview-Only content" option and selecting "Book" among the "Content type" filters. All e-books are free from DRM (digital rights management) constraints and can be accessed without limitation. It is important to point out this possibility to all our students who can download the volumes indicated by us in class. For example, the texts by Lacava, Pani and Vulpiani can be consulted. From October 2018 only the most downloaded volumes will be acquired by Sapienza on a permanent basis, so I would like to underline the opportunity of such an indication. Thank you for your attention The director Paolo Mataloni (translated by Google)
