Yes, my passbook gets updated once a year, at extension time. I'm just trying to avoid an extra visit to TTB. My passbook is full - certainly not enough room for an update so i do need a new one. Maybe TTB can provide one on the spot, when i go in for the statement and letter, but maybe not. It took them quite a few days to provide the annual statement, last year. Might be safer to get the new book a bit in advance - unless the e-book will do the job, which is why I asked if anyone had any experience of doing it that way.
