The Liturgy of the Hours is the official liturgy of the Church, along with the other official liturgy, the Mass.
There are a number of ways to involve yourself in the Liturgy of the Hours.
The simplest may be the Magnificat (sorry, I do not have the name of the publisher) which publishes a monthly (or more frequent) booklet with a small part of Morning Prayer and Evening Prayer, along with, I think, Night Prayer (Lauds, Vespers and Compline).
There is a longer one volume set which has the 4 weeks with Sundays and holidays (and I think Lent and Advent) called Shorter Christian Prayer. If you want more focus on the Liturgy of the Hours than the Magnificat gives, that is probably the best source.
Then there is the thick one volume of the Liturgy of the Hours (Shorter CP is about 3/4" thick, as opposed to the 1 vol. which is about 1 1/2" thick). Then there is the 4 volume set.
Whatever you do, don’t start with the 4 volume set; you will be overwhelmed.
Is it helpful to pray it? It is made up of primarily Psalms and OT readings. As a lay person you are not required to say it, or say it in a particular fashion (although it is certainly a good exercise to do correctly). It is better to pray than to not pray (any prayer). If the format works for you, you will find many blessings. It may not fit everyone and there is nothing wrong with that.
