The artist Tom Phillips does a lot in this space.
His novel A Humument is a ‘treated Victorian novel’ - he paints over the pages, with illustrations and patterns, hiding the original text, but leaving some words present to pick out a new story. It’s very, very beautiful; more on it here, and lots of pictures here.
Phillips has been painting it since 1966, though, and it’s into its fifth edition. Some pages get revised; some get totally altered. I have a print copy of the fourth edition - but I also have a print of one of the pages, and that print does not exist in my book. It’s changed between them. And the point of the work really is that it’s always changing, and the books are perhaps more like check-ins to version control? Or stable points, before instability occurs?
He also has a work called 20 Sites N Years in which every summer he spends a day taking the ‘same’ photograph with the same film stock and camera in 20 locations in Camberwell, an area he grew up in and lives in; obviously, they are not the same photograph. It was planned to run for 20 years, and he started in 1974; it just keeps going. I believe there are instructions in his will for how to continue it, and a safe containing film stock.
What’s the thing here, other than a favourite artist? Maybe designing change into the work, and the idea you can have a fixed ‘edition’ of a work you’ve been working on ince 1966 and continue to do so.
