Today, very few registers, other than those which are still in use, are held at churches. Many of the registers have been filmed and copies are widely available; ask at the relevant county record office or local studies library, or your nearest Church of Jesus Christ of Latter-Day Saints (LDS) Family History Centre. In addition to the registers, from 1598 parish priests had to send to their bishop an 'annual return', a copy of the register, known as a Bishops' Transcript. Those that still exist can be very useful in supplying entries omitted from the register or replacing a missing register.
