Guides in library's collections
Here are some examples of how to use different types of references in a reference list using the APA 6th (American Psychological Association) citation style in texts written in English. The author must always ensure that the in-text citations and the reference list follow the practice of the community or publication for which the publication is intended. Further information: Publication Manual of the American Psychological Association (6th ed.). (2010). Washington, D.C.: American Psychological Association (pp. 193-224).
When you cite a book, the reference list should include the following bibliographic information:

Citing authors with the same surname
Citations include the author and date, either both inside parentheses or with the author names in running text and the date in parentheses. Use always page numbers with direct quotations.
If a direct quotation is longer than 40 words, indent the paragraph:
xxxxxxxxxxxxxxxxxxx. (Author, year, page)
If direct quotation is shorter than 40 words: "xxxxxxxxxxxxxxx" (Author, year, page).
In other cases: xxxx (Author, year, pages).
Separate numbers in the page range using an en dash (–) in both APA editions.
If you cite the whole book or article, do not include page numbers.
Page numbers are included when citing an image, table or detailed information.
APA also encourages authors to include page numbers in other than direct quotations when it helps the reader to locate the relevant passage. If the cited material does not have page numbers, use a paragraph number. More information here.
