organise references alphabetically

Question

I have organised my bibliography as follows:

\begin{thebibliography}{99}

\bibitem[Author (date)]{code} 

Author Name (date).

\textit{Title}. 

Publisher.

etc

\end{thebibliography}

Is there any way to organise the references alphabetically?

If you build the bibliography by hand, you are in charge of absolutely everything -- including the order of the appearance of the items.

You may want to look into creating bibliographies via tools such as BibTeX, which has been around for decades, and biblatex, which is (much!) more modern than BibTeX and offers more formatting and sorting options than BibTeX does. If you choose the BibTeX route, do also look into using a citation management package (e.g., natbib) for options for generating citation callouts.
