The reason I was back in the IGIs was I still have far too many gaps in ScotlandsPeople for my people. I was hoping that between High Wallis's original site and the archer software site I would be able to reconstruct some gaps.
We all have gaps of that sort. The further back you go, the bigger the gaps.
In my tree I have 222 couples who were married in Scotland between 1750 and 1799. Of those, 76 are not in any records that I have been able to find. That is over a third.
You can see from the infomation supplied by R J Paton and myself that the 18th century Auchtergaven marriage records are defective.
The point is that, as far as Scotland is concerned, the IGI is an
INDEX to what is now on Scotland's People. if the originals do not exist, they cannot be on Scotland's People; therefore if they are not on SP they cannot be in the IGI.
The indexes at SP are regularly updated as and when new material or corrections come to light; the IGI is not.
If you find anything on the IGI that is not on SP, it must be regarded with suspicion until you have tracked down the source. Some listings in the IGI were from extremely dubious sources - there was, for instance, a set of baptism records of the Norse gods, though that has since been removed - and they are not to be trusted unless they can be traced to a credible source.
As for keeping things secret, this is nonsense. There is a complete, free to use, and regularly updated index at Scotland's People containing the same information as the IGI, plus other records - for instance to Roman Catholic registers - that are not in the IGI. And, once you find the index listing, you have instant access to images of the original documents, whereas using the IGI you would have had to go to an LDS Church Family History Centre, arrange to rent the relevant microfilm, wait for it to arrive, and go back to view the film and transcribe the information.
I was a huge fan and admirer of the IGI, despite its shortcomings, but expecting to use it to fill in gaps in the original records is a triumph of misplaced hope over bitter experience.
