When you think of all the technological changes since then it is astonishing it has taken something like 12 years before (a portion of) the same data has become available online from an official source.
Having sat in on many of the 'now defunct' GRO business user group meetings, putting the indexes online has never been on their 'to do' list, citing data protection and lack of funds.
The GRO's remit is to provide certificates and be part of the Passport service. The actual registration process is under the control of local authorities although there are still many registrars who were employed in those days way back when.
The demise of the DOVE and MAGPIE projects shows just how little they thought of digistisation and computerisation.
But the winds of change must be a-blowing there now. The availabilty of pdf's must have generated some extra revenue which they may be using wisely for our benefit. The cost of the certificates does not generate a profit, the GRO are not supposed to.
