I am working on a site that sells artwork prints online. On each page offering a print of an artist's work, the artist's bio appears before a text description of the piece. In some cases, the same artist's bio appears on as many as 200 different pages (because the site sells that number of the artist's pieces).
Since a canonical link has to be listed in the <head> section of a page, designating the entire page subordinate to the "master" page containing the bio, how do I tell Google that a section of the text on each art print's page is canonical? In other words, some of the text on the page (about the print) is unique, but the info about the artist is duplicated on other print pages.
