Some citation styles require to replace any subsequent occurences of the same author/bookauthor/editor byidem/eadem, their abbreviations id./ead., or some other term or symbol like a dash.

a) It may be that you need such replacementswithin the bibliography, e.g.

Doe, Johnson & Williams.2001.--- & Smith.2002.Doe, Stevens & Miller.2003.---, --- & ---.2004.

This ispossibleand just depends on the citation style you use.(If you want to use it in your own citation style, seesubsequent-author-subsitute rules in CSL.)

b) It may be that you need such replacementswithin one reference, for example for a work in an anthology (collected or selected work), e.g.

DOE, JOHN (1998): Article.In: IDEM (ed).: Book.

This is currently not possible, but as aworkaround188BET靠谱吗you can enter here in Zotero "IDEM" as the book author or editor, which will give you the desired result.

c) It may also be that you need suchreplacements for subsequent citationsof the same author but different books, e.g.

V.HUGO, Les Misérables, Livre de poche, 2002, p.127.ID., La Légende des siècles, Hatier, 1998, p.45.

This is currently not possible, but as aworkaroundyou can suppress the author here and add "ID., " manually.
