A source that is not listed as an inline citation in an article is not a reference, it does not point to any specific text in the article. It is ""further reading"" material unless it can be used to verify text.

Contents: These sections present (1) citations that verify the information in the article, and (2) explanatory notes that would be awkward in the body text. Some articles divide this type of information into two or more separate sections; others combine it into a single section. There is no consensus establishing a particular structure when footnotes and the works cited in those footnotes are placed in separate sections.
Title: The most frequent choice is ""References""; other articles use ""Notes"", ""Footnotes"", or ""Works cited"" (in diminishing order of popularity). The title ""References"" may be inappropriate if the section contains both explanatory notes and citations. Several alternate titles (""Sources"", ""Citations"", ""Bibliography"") may also be used, although each is problematic: ""Sources"" may be confused with source code in computer related articles; ""Citations"" may be confused with official awards or a summons to court; ""Bibliography"" may be confused with a list of printed works by the subject of a biography. With the exception of ""Bibliography,"" the heading should be plural even if it lists only a single item.[9]

Further reading
Shortcut:
WP:FURTHER
A guideline on further reading sections is proposed at Wikipedia:Further reading.
Contents: An optional bulleted list, usually alphabetized, of a reasonable number of editor-recommended publications that would help interested readers learn more about the article subject. Editors may include brief annotations. Publications listed in Further reading are cited in the same citation style used by the rest of the article. The Further reading section should not duplicate the content of the External links section, and should normally not duplicate the content of the References section, unless the References section is too long for a reader to use as part of a general reading list. This section is not intended as a repository for general references that were used to create the article content.
