Libraries have always been a valuable source of knowledge. The technology evolution transformed the traditional libraries into digital ones which arose the need of efficient serve of the huge amount of information that now exists in the form of digitized content. The focus of the monographic study “Multimedia Digital Library: Constructive Block in Ecosystems for Digital Cultural Assets. Basic Functionality and Services” is on the search of innovations especially in areas and subareas relevant to digital library data management and processing—innovative and creative tools for approaching cultural assets, applications and services for better access and exploiting of the rich and diverse digital cultural heritage in a sustainable way, intelligent curation, creative use/re-use and remix, reinterpretation, study, understanding, analysis, personalization, adaptation, semantics, etc. The research deals with important issues of handling data directly, affecting the economy (as presented by creative and re-creative industry), the public sector (cultural institutions—museums, libraries, galleries, etc.), education, and society as a whole.

The following paper presents an application of QR code marking of digital iconographical collections for their outdoor mobile access and exploring through the GUIDE@HAND audio tourist guide.

This paper demonstrates an approach for technology-enhanced learning, combining analysis, collaborative work, mobile learning (m-learning for short), discussion, and learning-by-authoring approaches in order to achieve more active participation of the learners during the reception of knowledge and to stimulate their creative thinking. The learners visit famous churches, monasteries, museums, etc., where they can see samples of Bulgarian Iconography supported by m-learning. They rely on the GUIDE@HAND platform containing personalized collections presenting location, historical data, pictures, etc. Multimedia and other information resources are delivered through the Virtual Encyclopaedia of the East-Christian Art digital library (BIDL)—a web-based environment for registration, documentation, access and exploration of Bulgarian iconographical artefacts. The main goal of the learners is to create their own learning material/project by analysing the available resources. The presented use case also involves collaborative work and discussion approaches in order to attract learners and support their more active participation in the learning process.
