<P> You can also add an ID number to the end of a citation . The ID number might be an ISBN for a book , a DOI ( digital object identifier ) for an article , or any of several ID numbers that are specific to particular article databases , such as a PMID number for articles on PubMed . It may be possible to format these so that they are automatically activated and become clickable when added to Wikipedia , for example by typing ISBN ( or PMID ) followed by a space and the ID number . </P>
