The separate listing of parts of the Roman Missal seems strange:
“Roman Missal (Sacramentary)
Order of Mass
Eucharistic Prayers for Masses of Reconciliation
Eucharistic Prayers for Masses with Children
Eucharistic Prayers for Various Needs”
The 2002 Missale Romanum included the “Eucharistic Prayers for Masses with Children”. But a later edition, I think in 2008, did not. So I see the justification for listing this separately. But the others I do not see as separate books.
The 1973 Directory for Masses with Children included in n. 43:
“It is recommended, moreover, that the individual conferences of bishops see to the composition of lectionaries for Masses with children.”
In the U.S.A. this was attempted. The letter from the Congregation was “… we grant permission for its experimental use but without granting a formal confirmation.
From the Congregation for Divine Worship and the Discipline of the Sacraments, 27 May 1992.” (ISBN 0899420885).
In a similar way there are books for Sunday Celebrations in the Absence of a Priest. The 1988 Directory for Sunday Celebrations in the Absence of a Priest included: “41. … The conference of bishops, or the individual bishop himself, may, in view of the conditions of the place and the people involved, determine more precisely the details of the celebration, using resources prepared by the national or diocesan liturgical committee, but the general structure of the celebration should not be changed unnecessarily.” In Australia this lead to the Pastoral Handbook for the Dioceses of Australia (ISBN 187552214X).
