Which MARC tag is represented for the statement of responsibility including the author?

The MARC tag that represents the statement of responsibility, which includes the author, is indeed 245. This tag is used to record the title and statement of responsibility of a resource and typically includes the main title, subtitle, and information about the principal contributors, such as authors, editors, or illustrators. The statement of responsibility is crucial for identifying who is responsible for the content of the work, making it an essential component of bibliographic records.

The tag 100, while relevant to authorship, is specifically used for recording the main entry personal name of the author or creator, without additional context such as title or subtitle. The tag 650 pertains to subject headings, while 300 is used to describe physical characteristics of the item, such as the number of pages or dimensions. Thus, 245 is the most appropriate tag for encompassing the title and the authorship information together.
