White text on a bright blue background with the Einstein Telescope logo. The text reads: “ET Blue Book has been cited over 100 times on INSPIRE!”

🚀 The ET Blue Book passed 100 citations on INSPIRE - just 4 months after being posted on the arXiv!
~550 pages, 300+ contributors, and already a pillar for #GravitationalWaves science.
Thanks to all building on this shared vision!
