2026 is a special year for HAL—it marks 25 years of sharing, innovation, and collaboration in service of research! You may have already noticed the anniversary logo on HAL’s homepage. This logo will accompany all our communications throughout the year, and you are welcome to use it in your own presentations.
A “25th Anniversary” poster and a dedicated bookmark are available for printing (PDF files with and without crop marks).
A Guestbook
This anniversary is also yours: researchers, faculty, PhD students, engineers, librarians—all of you who bring this platform to life every day and make it an essential tool for knowledge sharing.
To celebrate this milestone, we invite you to share a message, memory, or anecdote in our digital guestbook. Whether you’d like to share a personal story, explain what HAL means to you, or simply leave your mark, your contribution will be invaluable.
The guestbook will remain open all year. Your messages will later be compiled and highlighted as we celebrate this important milestone together. They will reflect the diversity and richness of HAL’s uses and the commitment of its community.
