Why is this book out of print?

[jmeltze]

I wanted to use mod_perl with the LWP modules, and I was 
recommended the Pelican book, "Web Client Programming with 
Perl".  I went looking for it and it is out of print.  Has another book 
replaced it in the O'Reilly library?  It seems like it has not lost its 
relevance.  A friend I know who has it says that it is exactly what I 
need.

Can anyone answer this, and/or point me in the right direction?

Thanks,

Jonathan
