SLUB is committed to the dissemination of knowledge with as few technical, legal or physical barriers as possible. We therefore make digital content available in the public domain or under free licenses, with due regard to the applicable law. SLUB's licenses, rights or usage instructions are stated for each collection and successively for each object.
For this reason, you should above all be able to freely use and distribute reproductions of works for which the copyright protection has already expired. These digital objects are therefore generally made available under the Public Domain Mark 1.0. You may copy, modify, distribute and perform these works, even for commercial purposes, without having to ask for permission in any way.
Digital objects whose originals derive from other institutions or which may not be published in the public domain for copyright or ancillary copyrights reasons are subject to terms and conditions of use or licensing that allow as free of use and re-use as possible.
Regarding digital objects made available under the Creative Commons CC-BY-SA 4.0 License, you may reproduce and redistribute their content, modify and build upon the work for any purpose, provided that you cite SLUB and/or the owning institution as the source. You shall also use the same license CC-BY-SA 4.0 if redistributed.
For digital objects made accessible under "Free Access - Reserved Rights", the following applies: you may use them for scientific and private purposes free of charge, provided you cite the complete source including the name of the author, but you may not modify them. The commercial use of these objects is subject to authorization and usually a fee, and requires the written consent of the copyright holder, who has the right to prohibit use on a case-by-case basis.
