<br>
<br><font size=2 face="sans-serif">A book I can recommend is "Building
websites with OpenCms" by Matt Butcher. </font>
<br><font size=2 face="sans-serif">It gives a general introduction into
the system usage (workplace-description), a description of the API (OpenCms-classes)
and ways of adapting the system individually (development of own modules).
</font>
<br><font size=2 face="sans-serif">Although it only deals with OpenCms
5 until now I think it was worth buying it. </font>
<br>
