CPAN, mcpan, MetaCPAN
Searching for a Perl module on Google will most probably lead you to a page on search.cpan.org, the old front-end of CPAN. By typing the letter 'm' in front of cpan.org in the URL, you can easily switch to MetaCPAN.
There you can jump to the latest version of the module or to the distribution containing the module.
This trick was also described in another article, but now it comes with a screencast.
