 \section{Introduction}
 Research software has been written and used for decades in a range of disciplines.
-It has been established that most research requires research software for its results~\autocite{Hettrick2015}.
-To solve pressing research challenges, better software is crucial~\autocite{Hannay2009, Goble2014}.
+It has been established that most research requires research software for its results~\autocite{Hannay2009, Hettrick2015}.
+To solve pressing research challenges, better software is crucial~\autocite{Goble2014}.
 During the past decade, it gained ever-growing attention and is becoming accepted as a research result on its own.
 %We follow here the definition: “Research Software includes source code files, algorithms, scripts, computational workflows and executables that were created during the research process or for a research purpose”, with full definition and discussion provided in~\autocite{Gruenpeter2021}.
