To cite a book in APA style (7th edition), include the following elements in the reference list:

• Author's last name, initials.
• Year of publication in parentheses.
• Title of the book in italics, with only the first word of the title and subtitle capitalized.
• Edition information in parentheses if it is not the first edition (not italicized).
• Publisher name (do not include the location).
• DOI or URL if available (especially for e-books).

Basic format for a book citation:

Author, A. A. (Year). Title of the book: Subtitle (Edition). Publisher. DOI or URL (if available)

Example:

Hasler, E. (2018). The built environment. Liverpool University Press.

In-text citation format:

• For a paraphrase: (Author, Year)
• For a direct quote: (Author, Year, p. Page number)

Example:

• Paraphrase: (Hasler, 2018)
• Quote: (Hasler, 2018, p. 107)

Notes:

• For multiple authors, list all authors up to 20; use "&" before the last author.
• For edited books, indicate editors with "(Ed.)" or "(Eds.)" after their names.
• For chapters in edited books, cite the chapter author and title first, then the editors and book title.

This guidance aligns with APA official style and university library recommendations
