The Bulgarian Iconographical Digital Library (available at http://bidl.math.bas.bg) is an Internet-based environment—a place where iconographical objects of different kinds and origins have been documented, classified, and exhibited in order to be widely accessible to both professional researchers and the wide audience. The icons presented in BIDL originate from the end of the twelfth to the beginning of the twentieth century and most belong to the Bansko-Razlog iconographic art, as well as from other schools and regions of Bulgaria: Triavna iconographic school, Samokov iconographic school, icons from Veliko Tarnovo, Sozopol, Rila Monastery, Arbanasi, etc.

The Bulgarian Iconographical Digital Library provides services for registration, documentation, access and exploration of a practically unlimited amount of Orthodox iconographical artefacts and knowledge, and end users can use this rich knowledge base through its interactive preview, complex object search, selection, and grouping. The digital objects could be grouped into thematic collections according to their topics, as results of searching, grouping, etc. For each object and collection, special meta-descriptions are created. They include data about the title, the artist, the period (in years and centuries), the school, the dimensions (width/height/thickness), the technique, the base material (type of wood, ground coat, etc.), the category, the location, the author (biographic data), comments (features of the icon such as state, founder’s and other signatures, previous restorations), etc. Also, they contain links to other digital objects and collections, keywords, and so on.
