Extension talk:BiblioPlus/Flow

require_once("$IP/extensions/BiblioPlus/BiblioPlus.php"); is outdated.

Now it should be:

load_extension( 'BiblioPlus' );

I installed the plugin, got my access key from isbndb.com, and placed a reference:

<biblio>

#StickWillams2009 isbn=978-0-240-52118-3

</biblio>

1. it does not display the bibliographical information
2. the link takes me to https://isbndb.com/d/book/.html which is a bogus address... what am I doing wrong?
