Bookbinder-Restorers apply traditional techniques (unstitch, prepare and sew the notebooks) or more modern (glue and attach the cover). The process must be as discreet as possible. Generally, they work on request for individuals or public administrations (libraries, courts, etc.). With the client, they determine the nature of the work to be carried out and the appropriate type of binding, and then select the appropriate materials, and finally, establish a quote.
