Scientific software is an indensible tool for the automatization and control of complex problems. But what is software? Software is a entirety of different kinds of objects which is developing dynamically and cannot be reduced to software code. Moreover, software plays a special role: Software is in the middle between models and simulations. The distributed development of software and the access to the software have led to new concepts and tools for maintaining software and software information. The swMATH service is a portal for mathematical software. It provides landing pages for each software entry. These landing pages contain general information about the software products and links to a lot of resources which describe or use the software, e.g., websites of the software, repositories, Internet archives, and publications citing a software. The integration and analysis of different resources allows a nearly complete overview about the Web information of a software. In the talk, new features and future extensions of the swMATH service are presented.
