What are ISBN, CIP, ISSN umbers?

I'll show my watercolour current style and old one in this post. Btw, do you know what ISBN and CIP? ISBN and CIP are like a birth certificate and a family register of a newly published book. Below, kind publisher Helen Chamberlin's explanations. "Every book published in Australia has to be registered at the National Library of Australia in Canberra by law. Every book gets an ISBN (International  Standard Book Number) and CIP (Cataloguing in Publication data ) from the National Library before publication - it is legally required to appear on the imprint page - you will see it there on the files." 

Oh, I see..., hum, hum (*Sadami is nodding). 

"So, the National Library of Australia has received advance information about the book so that they could issue the ISBN and  CIP for a publisher to put on the imprint page. When stock of the printed book is received, a publisher sends a copy to the National Library of Australia, as required by the same law," said Helen.  

Her say enlightened me.  

I answered, "ISBN = a birth certificate, CIP = a family register of a newly published book!" That understanding impressed (?!) Helen. "I've never thought of them like you!" Hahaha, we laughed together. (*New knowledge must be digested in an individual concept.) An ISBNnumber is a handy and accurate method to find out a published book. I go to a library and a book shop with an ISBNumber to get a book.

One more, ISSN (International Standard Serial Number) is a unique code to identiffy "serial" publications that include periodicals such as magazines, newspapers, annual reports, yearbooks, journals etc. Here's the information of ISSN at the National Library of Australia. In the publication process of Moon, I've gained a lot of legal knowledge that is essential for professionals. (*thank you, Helen!)

Btw, the first image is my recent work. The below was done "ages" ago. My style gets loose. Interestingly, both show a similar colour use. But the current one might use less colours than the old one. It's good to see my own growing in piled up works.  

An active artist needs incessant research and study which excites me and intrigues me so much. I've already moved on new picture book projects and other ongoings such as watercolour workshops for people with disability and so ons. I enjoy creating story boards and roughs for picture books, whilst preparing for the book launch, the solo exhibition and competitions. Like a bouncing bunny, I'm quite busy and full of joy.
You, too, have a creative and joyful time in painting.
Friends, Happy Painting!
