 			&lt;p&gt;Like many of &lt;a href="https://standardebooks.org/ebooks/charles-dickens"&gt;Dickens’&lt;/a&gt; works, &lt;i&gt;David Copperfield&lt;/i&gt; was published serially, then as a complete novel for the first time in 1850. Dickens himself thought of it as his favorite novel, writing in the preface that of all his works &lt;i&gt;Copperfield&lt;/i&gt; was his favorite child. This isn’t surprising, considering that many of the events in the novel are semi-autobiographical accounts from Dickens’ own life.&lt;/p&gt;
