ETH Library's general legal notice is in effect.
In addition, please heed the following for E-Periodica:
Any information on this website is provided as is, with no guarantee of completeness or correctness. No liability is assumed for damage caused by use of information from this website or as a result of the absence of information. This also applies to third party content which is accessible via this website.
ETH Library is the provider of the digitised journals. It does not hold any copyrights to the contents of the journals, which are generally held by the publishers.
The provided documents on E-Periodica are freely available for non-commercial use in teaching, research and for private purposes. Individual files or print-outs of articles may be passed to other persons together with these terms and conditions and the proper indication of origin.
The publishing of images in print and online publications is only permitted with the prior authorisation of the rights-holders. Systematic storage of parts of the electronic range on other servers also requires the written consent of the rights-holders.
We encourage the posting of links to pages of E-Periodica. Titles in E-Periodica can be accessed permanently by persistent link: http://doi.org/[DOI].
Using a Digital Object Identifier (DOI) allows electronic documents to be referenced in a stable, globally unambiguous and non-location-dependent manner. It guarantees reliability in citing sources even if the Uniform Resource Locator (URL) changes. This is why DOIs are suitable for permanently guaranteed citation in scientific papers.
DOIs cannot be called up directly in a browser but are translated into URLs by a resolving service. The persistent resolution of these links is carried out by the International DOI Foundation (IDF).
