About LIBER 202601The publishing problem
When a reader asks an AI instead of opening your catalogue — in Madrid, Barcelona, Mexico City or Buenos Aires — who owns the relationship, and who earns the revenue?

Bring together archives, articles, books, metadata and taxonomies from your existing systems.
Your content + your contextTurn that content into connected, source-linked knowledge that preserves context, relationships and provenance.
Connected, traceable knowledgeUse that knowledge to power your own AI agents, search, internal tools and new reader or licensed products — all under your control.
Your brand. Your product.03Client story · Quintessence Publishing
