The CTLO has a twofold mission. On the one hand, it strives to increase the volume of its databases at a high and steady rhythm, adopting a rigorous formal and philological standard (basing its texts on the best editions available, and providing reliable philological and historical background information on the text). On the other hand, the CTLO is continually looking to improve the functionality that can be applied to this large volume of texts. Needless to say, these two main aims go hand in hand: the large amount of philologically reliable data provides the foundation needed to elaborate valuable functionality, and developing this functionality is only worthwhile thanks to the volume and quality of texts to which it can be applied.
