	This script was written to generate the print files for the publication ''ongoing circulations'' to document a series of five collective learning sessions organised by Varia in 2022. Each session departed from a technological practice and made space for exploring, questioning and (re)turning (to) digital library software, plain text publishing protocols, web-to-print tools, high frequency radio communication, and colonial infrastructures. The publication is based on the format of the letter, a mode of address that was chosen to reach out to the participants of the sessions specifically, but could meanwhile also speak to a larger body of readers and invite them into the questions that were formulated and materials that were produced.
