On the left of the column you see a catalogue of the 50 works which can be sponsored right now. They are divided into the following groups: Manuscripts (European and others), Books, Music, Pictures, Maps, Globes. Each work has been carefully selected and described by the library's experts and allocated a sponsor price, based on the amount of time and the materials needed for the restoration.

Each work has a conservation record that describes in detail what will have to be done.

The catalogue naturally leaves room for the name of the sponsor or the logo, as well as room for a picture after the restoration of the work.
