How Do We Keep Track of Apostolic Succession?

A listener named Mike asks about records of apostolic succession and the laying on of hands by the bishops. Father Dave explains that there are websites that keep track of ordinations tracing back to the 1500s; however, we do not have much information before that. Father Dave points out that the Holy Spirit has been keeping apostolic succession together all these years, and in the Acts of the Apostles when the Sanhedrin wanted to kill Peter and the apostles, Gamaliel proclaims that if Christianity was man-made it would not last, but if it is from God no one will be able to destroy it.
