UNESCO’s Memory of the World
In 1992, the United Nations Educational, Scientific and Cultural Organization (UNESCO) established the International Program “Memory of the World.” The primary goal of this program is to ensure and promote the protection of documentary heritage of global significance. Memory of the World also raises awareness of nations’ documentary heritage within the context of humanity’s shared memory.
The register supports the creation of various reproductions and copies of these works (including digitization) to make them accessible to the public. At the same time, the program aims to protect and preserve the original works in appropriate conditions for future generations.
The Czech Republic maintains a National List for the Memory of the World Program and manages an Indicative List from which a document is nominated to UNESCO’s Memory of the World Register every two years.
In 2025, the Czech Republic will nominate Mendel’s Manuscript.

Mendel’s Manuscript
One of the most valuable artifacts of the Augustinian Abbey is the original manuscript by Gregor Johann Mendel (1822–1884) from 1865, titled Versuche über Pflanzen-Hybriden (Experiments on Plant Hybrids).
This unique document, handwritten by Mendel himself in neo-Gothic cursive known as “Kurrent,” consists of 12 bifolios. In this manuscript, Mendel summarized the results of his years-long experiments on heredity. It represents a foundational work in the early study of genetics and serves as the only surviving direct testimony to Mendel’s groundbreaking research.
