Irish Emigration Database

There's a new site concerning a replica famine ship called the Dunbrody based in Wexford now online at www.dunbrody.com. Amongst the gems online is a free searchable Irish Emigration Database, compiled from several sources. Here's a description from the site:
Now you have the opportunity to access a huge database of emigrants who sailed from Ireland in the nineteenth century. This database has been compiled in collaboration with the Balch Institute Philadelphia, and the Ellis Island Restoration Commission, and the Battery Conservancy, New York from the original passenger lists of ships, which sailed from Ireland and the UK.
The database is directly accessible at ww.dunbrody.com/database2.php
