'Pre-treatment in the PIEs framework' is the current working title - eventually it will be the subtitle - of the penultimate essay in the 'Un-finished business' essays collection (author and editor Robin Johnson; publication pending).

NB: It will also appear in the next collection of essays on Pre-treatment (editor Jay Levy, publication date t.b.c.)

Here we will have links to all of the examples of PIEs practice referred to in that essay, where there is supporting material in the Members' Library.
