Almost all reference databases have the - buttons. They lead to article full texts, if available. In case there is no licensed or free fulltext you get further information e. g. request the fulltext by delivery service.
All licensed databases and journals are accessible from within the IP range of the institute without login data. SFX only works within the IP range of the institute.
To support your research you can contact the Central Information Service of the MPS CPT Section or the Central Information Retrieval Service of the BM Section.
