Using embedded bibliography in LaTeX

For simple documents, full bibliography management may seem an overkill, especially in cases where the entries in the bibliography may never be used by other documents. In such cases a simple system of adding a section such as follows will do,

\begin{thebibliography}
...
\end{thebibliography}

An entry in this embedded system will look like as follows

\begin{thebibliography}

\bibitem{lamport94}
Leslie Lamport,
\textit{\LaTeX: a document preparation system},
2nd edition,
1994.

\end{thebibliography}

which can then be cited using the \cite{...} command in your latex document, with the citation key being the parameter to the \bibitem{...} command above. In this example, this would be \cite{lamport94}. This bibliography may then be verbatim added to your documents,
