Value type “bibliography (Q1631107)”: This property should use items as value that contain property “instance of (P31)”. On these, the value for instance of (P31) should be an item that uses subclass of (P279) with value bibliography (Q1631107) (or a subclass thereof). (Help)

This property and list of works (P1455)

How is this different from list of works (P1455)? --Shinnin (talk) 15:10, 21 September 2020 (UTC)

From my understanding, this property is more generic because it applies to all topic, not only to human. @Thierry Caro: may give his opinion about that. Pamputt (talk) 15:43, 21 September 2020 (UTC)

@Shinnin, Pamputt: list of works (P1455) is for people's works. The new property is supposedly the list of works about someone or something. Sometimes Wikipedia articles about persons cover both works by that person an works about that person and then one might use both properties here. Thierry Caro (talk) 15:48, 21 September 2020 (UTC)
