The set above enabled me to make books in the back of a tour bus at the top of the south island soon after. I made crude PDF files, started publishing as Landroverfarm Press. 8 years later I maintain a good rate of progress - ten different poems / publications a year, roughly. About 65 single sheet, fold out A3-sized books. Put into #poetryracks or boxed sets even. I make hardbacks and paperback versions. The plan was always to take a hobby, a past time, an obsession for the last 25 years and get really good at it.
You need a photocopier or a risograph or a web offset, a gluestick, a stapler, sissors, a box cutter for the 'Digest covers. Make the books in a public place, transparently. Use the wastestream. Don't end up mass-produced by anyone but yourself because as a poet you're a chaos business of 1.
