In this dissertation I discuss a small amount of the work of Margaret Tait. The Introduction offers a personal discussion on the profession of Archiving which I revisit in my conclusion. Section One provides a general overview of Margaret Tait’s life and influences. This brief biographical information serves as a background for the more substantial technical discussion in Section Two. Though I do enjoy Tait’s films and find her work compelling, I should emphasise that I am not concerned with providing a critique of Margaret Tait’s films nor a complete overview of her life and work. I deem that to be a quite different paper and one I am not interested in writing. My main purpose here is to trace the technical developments Tait made in her filmmaking and show how an understanding of her practices can help in the restoration and preservation of her films. I hope this paper also demonstrates that the biographical is inseparable from the technical and for the Archivist, these two approaches to Tait’s work are again inseparable from the ethical and philosophical dimensions of the idea of permanence.
