Dear AoIR friends and colleagues, We are delighted to share that our new book, Platforms: A Critical Introduction, has now been published by Polity (in the UK, and in August in the US). The book offers an accessible introduction to platforms and platformisation, examining platforms as companies, services, and technologies or infrastructures. Drawing on examples ranging from social media and e-commerce to AI platforms, we explore how platforms have become central actors in contemporary culture, economy, and society. You can find more information about the book here: https://www.politybooks.com/bookdetail?book_slug=9781509568109 Polity is currently offering a 30% discount with the code HVD30. Inspection/examination copies can also be requested from Polity via their website. Many thanks to everyone in this community whose work, conversations, and insights have shaped our thinking over the years. We hope the book will be useful in your teaching, research, and discussions. With best wishes, Anne Helmond and Fernando van der Vlist
