«Ein Sam·mel·su·ri·um» is a mixture of lexicon and magazine. The topics of the respective issues are simple terms that can be illuminated in different ways. The issue of the first edition is about masks.
The bookazine contains mixed articles, lyrics, definitions and explanations. Although these are sorted alphabetically like in a lexicon, they allow readers to read "criss-cross" by linking related chapters and articles, as in a magazine.
In order to separate definitions and factual explanations from the magazine section, the articles partly contain booklets that are more of a lexicon character.
In addition, the illustrations of this bookazine are masks that you can scan with an app and reveal another animated layer.
