Statistics

Statistics of views and downloading for each document can be obtained from the record page of each document by clicking the Usage statistics tab in the upper menu.
We consider views to be the access to a DDD document, also the downloading of the full text when this downloading is done from a page other than the full record page.
We consider downloads to be the access to the file that contains the document full text or, when it is not text, the viewing of any other kind of file (pictures, posters…). Downloads can be done from the full record page or directly from a search engine. For those records that contain more than one file, downloads for all files are considered together.
