Dear AoIR community, We are pleased to announce the publication of *Imagining the Internet(s): A Collaborative Glossary*, edited by Nathalie Fridzema and Anya Shchetvina, and published with the Institute of Network Cultures. The glossary brings together 28 keywords to help us think about the internet as an imagined object and each written by a different scholar, offering personal reflections rather than encyclopaedic definitions. Entries span sociotechnical imaginaries, infrastructural ideologies, vernacular metaphors, algorithmic folklore, net scepticism, and many more, grouped into five thematic clusters: Science & Regulation, Design & Materiality, Rhetoric & Representation, Affects & Reception, and Temporality & Scale. Each entry includes a list of recommended readings. The glossary grew out of Matter of Imagination, an open-format working group dedicated to studying the discourses, narratives, and tropes surrounding desired and undesired technosocial futures. It was made possible through funding from EASST. It is freely available for download at: www.networkcultures.org/publications We hope it proves useful for teaching, research, and anyone interested in this interest. Best wishes, Nathalie Fridzema and Anya Shchetvina -- *Nathalie Fridzema *| PhD candidate (Dutch) Web History, Technostalgia, Digital Heritage & Web Archives University of Groningen, Centre for Media and Journalism Studies LinkedIn <http://www.linkedin.com/in/nathaliefridz> | Google Scholar <https://scholar.google.com/citations?user=bSOBiE4AAAAJ&hl=nl&oi=sra> | Staff page <https://www.rug.nl/staff/n.fridzema/> Review coordinator for TMG - Journal for Media History <https://tmgonline.nl/> Blog, maillist & research initiative Matter of Imagination <https://matterofimagination.neocities.org/>
