Like other literature from antiquity, the text of the New Testament was (prior to the advent of the printing press) preserved and transmitted in manuscripts. Manuscripts containing at least a part of the New Testament number in the thousands. The earliest of these (like manuscripts containing other literature) are often very fragmentarily preserved. Some of these fragments have even been thought to date as early as the 2nd century (i.e., Papyrus 90, Papyrus 98, Papyrus 104, and famously Rylands Library Papyrus P52, though the early date of the latter has recently been called into question).
