A library that understands its own content

ELVIRA is more than a catalog. A pipeline of AI workers extracts text, tables, figures and formulas from each publication, embeds them with multilingual models, and exposes the result through semantic search, an AI assistant and standards-based lending.

Read

Embedded PDF viewer with annotation layer, BibTeX / RIS citation export and page-range sharing. Works for born-digital PDFs and OCR-recovered scans.

Search

Multilingual semantic search over the full corpus. A Slovak query finds relevant passages in English, Czech and German literature. An AI assistant answers questions over library content with passage-level citations.

Lend

OPDS 1.2 and 2.0 distribution. End-to-end Readium LCP lending — borrow, reserve, renew, return — with EdRLab certification in progress.

How the pieces fit

The interactive ecosystem map shows every component, every dependency edge and every standard ELVIRA implements. Useful if you’re deciding what to extend, fork or replace.
