What People Say
What sets it apart from other digital platforms right now are a ton of features and services that aren't available in other research platforms, but also the domain specificity and the ability to discover and access resources across all these geosciences...
SciX has curated content, so the accuracy of the result sets is higher than some of the other platforms available to our community.
ADS is the secret sauce that has made astronomical research possible for the last 30 years. As well as bringing new communities this valuable tool, this expansion recognises the increasingly interdisciplinary nature of our subject, connecting the astronomical literature with that of our sister subjects. In a world in which climate models developed for Earth can be tested on Mars, and where our knowledge of distant planets depends on models of solar activity, it makes no sense to stay in our own walled garden, but instead SciX throws the gates open.
Big scientific challenges - from the search for life in the universe to understanding solar activity and its impact on our planet - require researchers to work across traditional boundaries. SciX enables this by providing an open, connected platform that brings communities together and accelerates discovery.
