For anyone trying to sort out the significance of the various IGI batch numbers, I have found the following website useful: http://www.ancestrysolutions.com/Batch%20Number%20Table.html There are other websites out there, I just happen to like this one. I haven't checked out Jack's number because I think Pam has got there already and explained things well. All the best Chris

Here is another IGI Identification format..... Jenny IGI BATCH NO. INFORMATION Batch numbers beginning with A, L, M17, M18,T0, T90, 69409- indicate LDS Temple records and have limited access. Batch numbers beginning with C, E, J, K, M (except M17 and M18), P, T5, 725, 744, 745, 754- indicate extracted birth, christening or marriage record. E- Batches: Replace the "E" with an " M" and find the "M-" batch number in the IGI Batch Number Index. T-5-Batches: Just above the IGI entry with a "T-5-" batch number, you will find a nearly identical IGI entry with a different batch number. Use that batch number to find the source. 725-, 745-, and 754- Batches: These batches are extracted indexes, usually with no more information. Names may be listed alphabetically ...Surnames A - O are on film 543896. P - Z are on film 543897." Batch numbers beginning with F, T96, T998, T9990, and all digit numbers such as 8434961 [except beginning with 725-, 744-, 745-, 754- as above] are forms submitted to the Ancestral File by individuals. They may be a Family Group Record, an Individual Entry or Marriage Entry. The microfilms can be ordered and photocopies can be made. Submitters' names and addresses may be outdated. F- Batches: Check the forms to understand the data. Some information is estimated or added and may be different from what you expect. T96- Batches: This is a correction to an existing record.
