“ Files uploaded to Wikimedia Commons are visible as files (and can be used on pages just like local files) on all the Wikimedia projects (i.e. the various language versions of Wikipedia or of Wikisource) . Here on Wikisource the Mediawiki installation has a special extension (called ProofreadPage) that provides functionality specifically to support transcribing and hosting written works (books, magazines, etc.) . ”

“ Once the file exists we can create a page in the Index: namespace with the same name as the file. In this case that would be Index:Constitution of the kingdom of Italy.djvu. Based on the identical filename the software will figure out that the file and the index page are connected (and will even pre-fill some of the fields with information fetched from the file's description page at Commons) . An index page is a special wiki page that is presented as a form to fill out, with fields for giving the author, the title, the year of publication, and so forth. ”
