if you look at template cite book you can see the parameters for a template that defines a cited book i always use this template or others like template cite journal or template cite web because they automatically put the different bits of information into the right format template sfn gives a way to easily make a reference and footnote that link to the cited source thus displays as the trick here is that the cite book template includes ref harv which tells the template to make a footnote from the author's last name and the year of the book e g smith and link it to the book definition that may not always be possible because the author's name and or publication year may be unknown in which case you can tell the template what name to use for the footnote as in ref harvid norwegian blue enough you just have to explore and experiment hope this helps
