====Linking to Google Books pages====

{{further information|Wikipedia:Google Books and Wikipedia}}
[[Google Books]] sometimes allows numbered book pages to be linked to directly.
Page links should only be added when the book is available for preview; they will not work with snippet view. Keep in mind that availability varies by location. No editor is required to add page links, but if another editor adds them, they should not be removed without cause; see the [[Wikipedia_talk:Citing_sources/Archive_30#Linking_to_Google_Books_pages|October 2010 RfC]] for further information.

These can be added in several ways (with and without citation templates):
*Rawls, John. [https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 ''A Theory of Justice'']. Harvard University Press, 1971, p. 18.
*Or with a template: {{cite book |last=Rawls |first=John |title=A Theory of Justice |publisher=Harvard University Press |date=1971 |page=18 |url=https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18}}
*[https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 Rawls 1971, p. 18].
*[https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 Rawls 1971], p. 18.
*Rawls 1971, [https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 p. 18].
*Rawls 1971, [https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 18].

In edit mode, the URL for p. 18 of ''[[A Theory of Justice]]'' can be entered like this using the {{tl|Cite book}} template:

<syntaxhighlight lang="wikitext">{{cite book |last=Rawls |first=John |date=1971 |title=A Theory of Justice |url=https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 |publisher=Harvard University Press |page=18}}</syntaxhighlight>

or like this, in the first of the above examples, formatted manually:
<syntaxhighlight lang="wikitext">Rawls, John. [https://books.google.com/books?id=kvpby7HtAe0C&pg=PA18 ''A Theory of Justice'']. Harvard University Press, 1971, p. 18.</syntaxhighlight>

When the page number is a [[Roman numeral]], commonly seen at the beginning of books, the URL looks like this for [https://books.google.com/books?id=kvpby7HtAe0C&pg=PR17 page xvii] (Roman numeral 17) of the same book:<br />

{{in5}}<code><nowiki>https://books.google.com/books?id=kvpby7HtAe0C&pg=PR17</nowiki></code><br />

The <samp>&pg=PR17</samp> indicates "page, Roman, 17", in contrast to the <samp>&pg=PA18</samp>, "page, [[Arabic numeral|Arabic]], 18" the URL given earlier.

You can also link to a [[tipped-in page]], such as an unnumbered page of images between two regular pages. (If the page contains an image that is protected by copyright, it will be replaced by a tiny notice saying "copyrighted image".) The URL for [https://books.google.com/books?id=dBs4CO1DsF4C&pg=PA304-IA11 eleventh tipped-in page inserted after page 304] of ''The Selected Papers of Elizabeth Cady Stanton and Susan B. Anthony'', looks like this:<br />

{{in5}}<code><nowiki>https://books.google.com/books?id=dBs4CO1DsF4C&pg=PA304-IA11</nowiki></code><br />

The <samp>&pg=PA304-IA11</samp> can be interpreted as "page, Arabic, 304; inserted after: 11".

Note that some templates properly support links only in parameters specifically designed to hold URLs like {{para|url}} and {{para|archive-url}} and that placing links in other parameters may not link properly or will cause mangled [[COinS]] metadata output. However, the {{para|page}} and {{para|pages}} parameters of all {{cs1}}/{{cs2}} citation templates, the family of {{tl|sfn}}- and {{tl|harv}}-style templates, as well as {{tl|r}}, {{tl|rp}} and {{tl|ran}} are designed to be safe in this regard as well.

Users may also link the quotation on Google Books to individual titles, via a short [[permalink]] which ends with their related ISBN, [[OCLC]] or [[Library of Congress Control Number|LCCN]] numerical code, e.g.:
<code><nowiki>https://books.google.com/books?vid=ISBN0521349931</nowiki></code>, a permalink to the Google book with the [[International Standard Book Number|ISBN]] code 0521349931.
