Dear Tinho The National Library of Australia holds both series and we file them separately. We have also indexed them separately so it is clear what our holdings are for each series. I don't know enough about the issues for each series to comment on whether different sheets have been issued in each, but I am sure someone on the list will know!

Should the older 1:63 360 maps be filed with or separately from the newer 1:50 000 maps? In my collection they are all mixed together in sheet order, but as I'm in the process of buying a number of new sheets I wondered if it was time to separate the two. This would have the pragmatic result of not having lift so many maps out of the drawer when searching for a sheet. I wait, as ever, agog for your collective wisdom.
