Here is a passage from Wikipedia:
Father Hardon's work The Catholic Catechism was a significant post–Vatican II work in the sense that it essentially brought modern Catholic teaching and faith into one book, unlike any other before. At the time of his death it had sold over 150,000 in hardback, and as a 623-page paperback had reached its 26th printing selling over one million copies. **It served as the normative standard until the publishing of 1992's Catechism of the Catholic Church, which is the official codified teaching of the Catholic Church, promulgated by Pope John Paul II. Hardon served as a consultant for the drafting of that document.**
Does that mean this book was considered to be the "norm" document that all Catholics were obliged to obey like they do with the CCC during that time?
