IDLE: pravděpodobně to bude obšlehnuté z téhle statistiky:
https://www.fep-fee.eu/European-Book-Publishing-Statistics-2022 : "The total annual sales revenue of book publishers of the EU and the EEA in 2022 was approximately € 23.9 billion, according to the survey conducted by FEP. This represents a small increase from 2021 (23.6), the result of mixed outcomes across countries. The largest markets in terms of publishers’ turnover were Germany, the UK, France, Italy and Spain. Total market value is estimated at 36-38 billion €."
