At mr - wikisource we are in need of interwiki page import facility, since we are in need of importing considerable number of pages time to time since many new people post source documentation pages mistakenly at mr-wikipedia or mr-wikibooks (To transfer pages categorised wide category w:mr:वर्ग:Transferable to Marathi Wikisource); we need to transfer those to mr-wikisource along with page history ;
Secondly we need to transfer templates (specialy related to copyrights and help etc ) we need facility to import templates from following projects
Third we might need import facility to trannsfer some pages for translation purposes along with page history from English, Sanskrit and Hindi wikisource ( Hindi pages are currently located at wikisource.org)
