You need to clarify, though, that these are not complete manuscripts.  For instance, the P52 fragment from the Gospel of John is the size of a credit card:

P.S. In fact, here's a list of all New Testament manuscripts:

Sorry what I meant was manuscript not "manuscripts", and I was referring to P75:




Just to explain it since you probably can't read Greek - it's late 2nd century and on the same page that Luke ends (pictured above) John begins. I hope that clears that up. The manuscript is mostly complete, I'm not looking it up, but it has about 100 leaves (pages) that still exist today of the original representing more than 60% of the original manuscript. And of course it's Papyrus (made from reeds), not Parchment (animal skin); with parchment writings being much more durable of course.

P52 is fairly unique, most manuscripts are not a single scrap of a manuscript, again without looking it up the average length of a NT manuscript is over 400 pages: but most of those are from the 4th century on and are parchment. When looking at papyrus, those are generally earlier, and the break down and turn to dust much quicker, and they had less books (if any) bound together. In this case, P75 is just Luke-John, whereas your 4th and 5th century manuscripts usually contain the whole New Testament.
