The LDS has organised the records in the IGI into 'batches'. These batches relate to how and when the information was extracted from source material.

An excellent list of Batch numbers appears here:
http://freepages.genealogy.rootsweb.ancestry.com/~hughwallis/IGIBatchNumbers.htm
There is a useful explanation also at http://www.genuki.org.uk/big/FindingBatchNos.html

One this page I have attempted to organise some Shropshire families by identifying them via the batch number associated with the source material.

The batch numbers on this site belong to the Church of Jesus Christ of Latter-day Saints
