However, these forms were abandoned, in the UK at least, due to the Data Protection act. 'Publishers' still keep track of such info, but no longer on any official Society paperwork.
As "passwordprotected" said here in UK we used to use the S8 "House to House Record" slip. We would write down "not-at-homes" on it.
Also details of anyone who actually bothered to talk to us. Usually gender, subject talked about, any publications placed etc. Any other info that may prove useful when making a "return visit".
Then as said the "Data Protection Act" came into force and the WT scrapped the S8 form. We were told we had touse our own notebooks to keep records of calls etc.
But if you had a list of "not at homes" you couldn't give another JW the page they were written on from your notebook. You had to verbally tell them and they would write them down in their notebook. As giving them the page from your notebook was deemed to be breaking the "Data Protection Act."
