cite elementHTMLElement.The cite element represents the title
  of a work (e.g.
  a book,
  a paper,
  an essay,
  a poem,
  a score,
  a song,
  a script,
  a film,
  a TV show,
  a game,
  a sculpture,
  a painting,
  a theatre production,
  a play,
  an opera,
  a musical,
  an exhibition,
  a legal case report,
  etc). This can be a work that is being quoted or
  referenced in detail (i.e. a citation), or it can just be a work
  that is mentioned in passing.
A person's name is not the title of a work — even if people
  call that person a piece of work — and the element must
  therefore not be used to mark up people's names. (In some cases, the
  b element might be appropriate for names; e.g. in a
  gossip article where the names of famous people are keywords
  rendered with a different style to draw attention to them. In other
  cases, if an element is really needed, the
  span element can be used.)
This next example shows a typical use of the cite
   element:
<p>My favorite book is <cite>The Reality Dysfunction</cite> by Peter F. Hamilton. My favorite comic is <cite>Pearls Before Swine</cite> by Stephan Pastis. My favorite track is <cite>Jive Samba</cite> by the Cannonball Adderley Sextet.</p>
This is correct usage:
<p>According to the Wikipedia article <cite>HTML</cite>, as it stood in mid-February 2008, leaving attribute values unquoted is unsafe. This is obviously an over-simplification.</p>
The following, however, is incorrect usage, as the
   cite element here is containing far more than the
   title of the work:
<!-- do not copy this example, it is an example of bad usage! --> <p>According to <cite>the Wikipedia article on HTML</cite>, as it stood in mid-February 2008, leaving attribute values unquoted is unsafe. This is obviously an over-simplification.</p>
The cite element is obviously a key part of any
   citation in a bibliography, but it is only used to mark the
   title:
<p><cite>Universal Declaration of Human Rights</cite>, United Nations, December 1948. Adopted by General Assembly resolution 217 A (III).</p>
A citation is not a quote (for
  which the q element is appropriate).
This is incorrect usage, because cite is not for
   quotes:
<p><cite>This is wrong!</cite>, said Ian.</p>
This is also incorrect usage, because a person is not a work:
<p><q>This is still wrong!</q>, said <cite>Ian</cite>.</p>
The correct usage does not use a cite element:
<p><q>This is correct</q>, said Ian.</p>
As mentioned above, the b element might be relevant
   for marking names as being keywords in certain kinds of
   documents:
<p>And then <b>Ian</b> said <q>this might be right, in a gossip column, maybe!</q>.</p>
