By 2004 the Beazley Archive had more than twenty databases of different types of objects in different formats. To manage data more efficiently they were merged into one 'extensible' database system (XDB) between 2004 and 2005. Merging datasets also enabled the 'benefits' of one database to be transferred to another. For example, a database of inscriptions on Athenian vases was merged with the Pottery Database, and the latter was merged with Corpus Vasorum Antiquorum.

Users can search individual databases or a combination.

The merger was also a preparatory step towards the virtual integration of datasets of classical art held in a number of European research centres.

The front-end screens of all of the Beazley databases are being redesigned to enable novice users to search more easily.
