I figure it's about time I shared some of the information in Marja's book, co-authored with Giacomo Macola, although I have to say to anyone reading this that I am not in Zambia and can't pop over to the archives to look up anything for you, sorry. Access to the archives is not free (you can see prices at the link above). I believe that the book, published by the National Archives, sponsored by the Finnish Embassy, is still available in some shops in Lusaka.
It looks to me like the archives have a new website, which is a good sign. However, the introduction to this book raises concerns about the state of the archives:
"...underutilized, inaccessible and often in imminent danger of decay or destruction, owing to lack of resources and informed support."
I myself donated a copy of a Focus On Zambia documentary film to the archives, though I can't see a record of it -- I do know that it has been put to use at least once. I've wondered from time to time about donating other materials, but the comment above has been in the back of mind also. Anyway, if I were working there I'd be digitising as much as possible, as soon as possible.
Bringing to the public's attention what is available is a key step in providing impetus to use of the materials and therefore their preservation, and yet the current website does not seem to list the materials I'll refer to here, ten years after the publication of this book. The archives website mainly seems to refer to governmental records.
The authors point out that there was a colonial bias to the collections of the Non-governmental archives, and that they began their project with creating a list of office-bearers in nationalist organisations and the first government, with a view to obtaining further archival materials. This met with some success, but the records remained sparse at the time of writing (2004). Further collections under the non-governmental umbrella are missionary and church archives, political organisations and NGOs dating from the colonial period.
As far as I know a mooted follow up project 'A Guide to Zambiana Archives Abroad' has not come to pass, but interested readers would do well to look at records held by SOAS (School of Oriental and African Studies) in London. Apart from Sampson's book 'They came to Northern Rhodesia' (I have this, ask me for a lookup), the authors also recommend K.G. Mlenga's 'Who's Who in Zambia ' 1967-68 for biographical information. Another archive that should be worth exploring is the Collection Division of the Library of the University of Zambia.
What follows below is a brief summary of the archival materials listed in the book, without much regard to consistency. There is further detail on these in the book. Some collections remain in private hands, but are open to researchers. I've tried to indicate where this is so by mentioning their rough location.
