Link list between old sl. no and new sl. no in the new roll

All EROs and AEROs to please note that an elector in a particular sl. no. in the last Electoral roll with 2009 as the base year will now appear in another sl. no. (without any apparent rationale)in the new electoral roll to be published in draft on 09.07.10. For example, elector with sl no. 1 in old roll can now be found in sl. no. 898 in the new roll or in another Part and AC old sl. no. 2 would appear in sl. no. 237 in the new roll.
So to help the electors to identify their new sl. no. we are going to give the BDOs 2sets of printed link list per part per AC, 1) for DO 2) for BDO office. We can also give soft copies to the BDOs in their pen drive if they so need it, for that they may visit this office.
We are going to give all the political parties the same list in soft copy in a CD.
