During the 20th century, librarians were concerned about keeping track of the many books being added yearly to the Gutenberg Galaxy. Through a global society called the International Federation of Library Associations and Institutions (IFLA), they devised a series of tools including the International Standard Bibliographic Description (ISBD).

Each book is specified by an International Standard Book Number, or ISBN, which is unique to every edition of every book produced by participating publishers, world wide. It is managed by the ISBN Society. An ISBN has four parts: the first part is the country code, the second the publisher code, and the third the title code. The last part is a check digit, and can take values from 0–9 and X (10). The EAN Barcodes numbers for books are derived from the ISBN by prefixing 978, for Bookland, and calculating a new check digit.

Commercial publishers in industrialized countries generally assign ISBNs to their books, so buyers may presume that the ISBN is part of a total international system, with no exceptions. However many government publishers, in industrial as well as developing countries, do not participate fully in the ISBN system, and publish books which do not have ISBNs.
Books on library shelves with bookends, and call numbers visible on the spines

A large or public collection requires a catalogue. Codes called “call numbers” relate the books to the catalogue, and determine their locations on the shelves. Call numbers are based on a Library classification system. The call number is placed on the spine of the book, normally a short distance before the bottom, and inside.

Institutional or national standards, such as ANSI/NISO Z39.41 – 1997, establish the correct way to place information (such as the title, or the name of the author) on book spines, and on “shelvable” book-like objects, such as containers for DVDs, video tapes and software.

One of the earliest and most widely known systems of cataloguing books is the Dewey Decimal System. This system has fallen out of use in some places, mainly because of a Eurocentric bias and other difficulties applying the system to modern libraries. However, it is still used by most public libraries in America. The Library of Congress Classification system is more popular in university libraries.

You do not have to possess extraordinary skills to become an author. If you feel that you know something and that you are ready to share it to the world then it would be the best to pen it down for others to read. Similarly, for people who love writing novels or short stories, getting their first book published, would be no less then an achievement. However, always keep in mind that you are sharing something that you already know. This simple sentence holds a lot of importance because it will help you make your book content interesting since you already hold enough knowledge about it. You might have been averse to revision in school but you will have to do it for your novel. You will have to keep revising on your writing skills. Another word that you should never forget here is “read”. Brushing up your reading skills will in fact help you out when you pen your short story or novel.
