«Ex-libris ownership stamps were imprinted in books to clearly indicate to
which collection these literary works belonged. They were first seen in China
from where they were brought to Japan. While we can trace Japan's oldest
ex-libris ownership stamps back to the Nara period (710 to 794), we cannot

We would like to introduce a selection of 30 ex-libris ownership stamps allowing you to sample the historical aspects and charm of the culture of these stamps that are a part of the meticulously kept collection housed at the National Diet Library».

In Europe, ex libris in print form had to wait for the «invention» of printing by Guttenberg. Till then they were manuscript in the folios of the great monastic or princely libraries.
A testimony of the great cultural heritage of the Japanese civilization and an example of what some western Libraries that hold large bookplate collections should do.
