Global vars are a Very Bad Thing. Especially if 
you want to reference them from libraries. It's 
not really a library if it requires a global 
variable. If your library performs common 
routines with database handles, then make the dbh 
the first parameter to the function:

myLibrary::doSomething( $dbh, ... )

However, if you must use 'Global Variables', then in your main file:
use vars qw/$globalvar/;
$globalvar = 'some value';

And in your library, you can just use it:
print $globalvar

Or, if your libarry contains a package, use it as:
print $main::globalvar

Once again though, global variables are a bad thing

    ( Maybe have a look at going OO, then your     )
.oO( object can contain your 'globals', including )
    ( database handles, cache objects & parameters )
