While the number of libraries, databases and publishers (academic as well as non-academic ones) designated primarily for visually impaired users is increasing, it is becoming more complicated to browse and search them. A user has to open and interact with a lot of varied catalogues to find publications in accessible format (i.e. an accessible e-document, tactile prints, audio or hybrid publications). DALETH - Library Gateway by Masaryk University allows searching in one application putting one query to several libraries in the same time. Thus, it eliminates the necessity to use various interfaces and different tools for the same type of activity.

The app is a mobile version of the web application (www.teiresias.muni.cz/daleth). Besides searching itself, it allows downloading e-documents from those libraries the user is authorized for.
