Authordatetyylien

Authordatetyylien are a family of bibliographic citation styles used in scholarly writing. They emphasize the author and the date of publication in in-text citations, with full bibliographic details provided in a reference list. In-text citations can appear as (Author, Year) or as Author (Year), depending on context and style guide. The year helps readers assess currency, while the author signals accountability and authority. When a work has multiple authors, rules vary, typically listing up to a certain number before using et al.

Examples of Authordatetyylien include the American Psychological Association (APA) style, The Chicago Manual of Style's author-date system, and the Harvard referencing system. Differences among them concern punctuation, order of elements, italics, capitalization, treatment of page numbers for quotations, use of 'et al.', and whether the publication year is placed before or after the author name in narrative citations.

Usage. Many scientific fields require an author-date style; publishers and universities prescribe a specific variant. In Finland, these styles are commonly taught and used in academic writing, with local adaptations to Finnish language conventions and to accommodate bilingual sources. The choice of style typically affects both in-text citations and the reference list arrangement; consistency and access to reliable style guides are essential for accuracy.
