Where composers go?

the music is obviously beautiful. The performers are excellent, no complaints from that side .. This is a good approach to the so-called classical music ...
But why, unless I am mistaken that has downloaded this album, the composer's name is not he listed beside the title (also still incomplete) of the work and interpreters or the conductor? ????
Composers and the full title of the works which belong "extracts" are notably absent. This is an intolerable gap. So I put "I hate" to attract attention. Beautiful Miserere? The Choir of Trinity College superb, but the fact how mass and which composer owns this Miserere? ... And it's like that for "50 Treasures" illustrious anonymous.
