<p>The <code>bookmark?</code> method can be used to check the existance of a particular ID within the whole document, while the <code>bookmark</code> method is used to store bookmark IDs and titles. In a similar way, you can use <code>header?</code> and <code>header</code> methods to check the existance of headers within the documents or store new ones.</p>
