This 111-item FRBR group includes versions of Coriolanus, Cymbeline, and King John in addition to several editions of Hamlet. Many lack a uniform title.
This 15-item FRBR group contains mostly versions of Plato's Republic (with uniform title "Republic"), but the first two titles in the group are not the Republic. Item 1 (an ebook) has no uniform title at all, while item 2 (a print book) has a uniform title of "Works."
This 38-item FRBR group includes both complete and partial versions of Virgil's The Aeneid. We think this is happening because the records have a common uniform title, but still wish they didn't FRBR together.
Similar to the Aeneid FRBR group, this 20-item group for the Canterbury Tales includes 5 items that consist only of the work's prologue. See, e.g., http://bit.ly/2EVDfGy.
