The author may publish his/her LNCS contribution on his/her personal Web page
provided that he/she creates a link to the containing volume of LNCS
at the Springer-Verlag server 
<a href="http://www.springerlink.com/">
http://www.springerlink.com/</a>)
or to the LNCS series Homepage (URL:
<a href="http://www.springer.de/comp/lncs/index.html">
http://www.springer.de/comp/lncs/index.html</a>).
In the case of a contribution to a Springer journal, such as Requirements
Engineering, the author must create a link to the containing issue of the
journal, accessible via
<a href="http://rej.co.umist.ac.uk/">
http://rej.co.umist.ac.uk/</a>).
Together with this electronic version it is clearly pointed out, by
prominently adding ``(c) Springer-Verlag'' that the copyright for this
contribution is held by Springer. From the Publisher's point of view,
it would be desirable that the full-text version be made available from
the Author's Web page only after a delay of 12 months following the
publication of the book, whereas such a delay is not required for the
abstract.
