Ex Libris, (meaning: Book note) is a fascinating subject that
preoccupies me in recent years.

Choosing a person or a subject to whom it is dedicated is very
interesting by itself.

There are clear rules about designing them.
Whoever engaged in it must follow them.

On my site you can find several Ex Libris that I designed recently.
"Ex Libris is a Latin phrase, meaning literally,
"from books." It is often used to indicate ownership of a book,
as in from the books of... or from the library of... A bookplate,
which is also sometimes known as an ex libris".
