Due to the changes in state, political and public life of Russia LBC has been entirely redesigned. In 1997, the publishing house «Libereya» has issued a book «Library-bibliographical classification: worksheets for public libraries» as the supplement to the journal «Librarian». They are the source of the indexes of this system, which should be placed at the back of the title page of publications and in the layout of the annotated catalogue cards.

Since 2003 the publishing house «Libereya» has been producing «Additions and changes to the worksheets for public libraries» as separate numbered issues. These issues have replaced the extracts from 1997 edition and are mandatory for all publishing houses and organizations.
