Why did we never get a complete pew book for the 1960's Liturgicon?

A necessary qualification before an answer is possible: what, exactly, do you mean by complete?

John,

I am going to have to clarify something for you. A Liturgikon is the priest's liturgy book that would include all of his prayers and rubrics. The introduction of a People's or Pew edition is a relatively new thing. Generally it is minus the rubrics and in some cases the priestly and diaconal dialogue and priestly prayers. It may be to cut down on additonal printing costs, since in most cases they want the faithful to be aware of their parts in the responses only. In most cases, the rubrics have no bearing on the faithful directly, and thus are omitted.

I hope this helps.

In IC XC,

Father Anthony bless me a sinner.

As an altar server, I've followed along in the Liturgicon a few times to get a sense of what the rubrics are and what parts of the DL we're omitting.

I wonder why there was never a proper and complete pew book produced with all the antiphons, etc. for the laity.
