This page lists manuscripts and witnesses only through the eighth century.
Some witnesses are listed more than once, because in some books they are of one branch but in other books a different branch.
There has recently been a trend toward earlier dating of papyri.
The Gospel of Luke was written by the same author as the Acts of the Apostles, who refers to Luke as the 'former accountant' of 'all that Jesus began to do and teach' (Acts 1:1).
The destiny ('Theophilus'), style, and vocabulary of the two books betray a common author. The significance of Gallio's judgement in Acts -17 may be seen as setting precedent to legitimize Christian teaching under the umbrella of the tolerance extended to Judaism. The prominence and authority of the Sadducees in Acts reflects a pre-70 date, before the collapse of their political cooperation with Rome. The relatively sympathetic attitude in Acts to Pharisees (unlike that found even in Luke's Gospel) does not fit well with in the period of Pharisaic revival that led up to the council at Jamnia.
Look up any GNT citation, and you will see the readings of the various early manuscripts for that text.
