Bibliografia polska: Stólecie XV.-XVIII. w układzie abecadłowym: t. 12-34:1. A-Załuskich

The Bibliografia polska is the definitive multi-volume retrospective bibliography of Polish literature, spanning the 15th through the 18th centuries. Initiated by the scholar Karol Estreicher in the 19th century, the project was envisioned as a comprehensive national bibliographic record to preserve the intellectual history of Poland. The volumes are meticulously arranged in an alphabetical system, serving as an indispensable tool for historians, philologists, and researchers studying the cultural output of the Polish-Lithuanian Commonwealth.

Karol Estreicher worked on this monumental compilation throughout his career, with his descendants later continuing the exhaustive task. The design of these volumes reflects the rigorous, scholarly standards of 19th-century European archival practice, prioritizing dense information density and systematic classification. While individual volumes were published over many decades, the work is universally regarded as a foundational pillar of Polish humanities and remains a primary reference point for identifying early modern Polish printed materials.
