User Feedback: The revisions were informed by feedback from librarians and other users of the system, ensuring that the changes met the practical needs of those who rely on the DDC for organizing and accessing information.
Technological Integration: The 22nd edition also considered the impact of digital resources and the increasing importance of electronic media in libraries. This included updates to classifications related to technology and digital information.
