Does Catholicism allow the possibility of new books being added to the Bible? The Catholic Church recognizes 73 books in the Bible (46 in the Old Testament and 27 in the New Testament). Does the Church allow the possibility of new books being added to the Bible, perhaps in a "Newer Testament", thus giving them equal weight to other scriptures? By "new books", I mean books that were written after the writings of the currently recognized books of the Bible.

To give a concrete example, let's say that St. Joe Schmoe wrote a short book in 1900. Would it be possible for the Catholic Church to decide that the book of Joe was divinely inspired, like the currently recognized Bible books, and should be added to future copies of the Bible, thus allowing it to also be read during mass and such? I realize such an event is unlikely, but I'm wondering if it is theoretically possible to do it.
The very short answer to this question is no.


  Public revelation, or divine revelation, is God revealing himself to humanity. The Church teaches that public revelation, as revealed in salvation history, was perfected and completed in Jesus Christ.
  
  “The Christian economy … since it is the new and definitive Covenant, will never pass away; and no new public revelation is to be expected before the glorious manifestation of our Lord Jesus Christ” [see Dei Verbum 4; see also 1 Timothy 6:14; Titus 2:13]. Yet even if Revelation is already complete, it has not been made completely explicit; it remains for Christian faith gradually to grasp its full significance over the course of the centuries (CCC, 66). 
  
  The Church has long taught that public revelation ended with the death of the last apostle, as the Apostles faithfully taught Jesus’ message. The Church carefully guards its deposit of faith, awaiting its fulfillment in the final coming of Christ. - Public versus private revelation


Any saints' writings after the death of the Apostle St. John in ca. 100 AD are to be considered "private revelation" and are not binding to be followed or believed in by any member of the Catholic Church.


  In this respect, let us listen once again to the Catechism of the Catholic Church:
   "Throughout the ages, there have been so-called 'private' revelations, some of which have been recognized by the authority of the Church... It is not their role to complete Christ's definitive Revelation, but to help live more fully by it in a certain period of history" (No. 67). - Public Revelation and private revelations


Let us carefully remember that the Apostles were eyewitnesses to the events surrounding Our Lord Jesus Christ and future writers can not make this claim. St. John concludes his Gospel with the following words:


  This is the disciple who is bearing witness to these things, and who has written these things; and we know that his testimony is true. 25 But there are also many other things which Jesus did; were every one of them to be written, I suppose that the world itself could not contain the books that would be written. - Gospel of St. John Chapter 21: 24


Catholic Bibles usually end with The Apocalypse of St. John the  Apostle and although he gives to us a warning not to change anything written in the Apocalypse, it could also be used as a word of caution not to add to public revelation.


  For I testify to every one that heareth the words of the prophecy of this book: If any man shall add to these things, God shall add unto him the plagues written in this book. And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from these things that are written in this book. - The Apocalypse of St. John the  Apostle, 22: 18-19
