list of repositories on main page

line 875 (ish) contains a query that goes into shelfmark_view to fetch the list of repositories. Change the query to run off to look in dataforgraph_view.

Change :
$query = "SELECT DISTINCT repository_fulltitle, id_archoncode FROM shelfmark_view ORDER BY repository_fulltitle";

to:
$query = "SELECT DISTINCT repository_fulltitle, id_archoncode FROM dataforgraph_view ORDER BY repository_fulltitle";
