1, classification system
Libraries usually adopt a classification system, such as international federation of library associations and institutions International Standard Classification (UDC).
Or the Library of Congress Classification (LCC) of the American Library Association (ALA). These classification systems classify books according to disciplines, themes or other specific criteria.
2. Record cataloging
Libraries usually determine the position of each book on the shelf according to its cataloging record information. Cataloging records include the title, author, publication date, ISBN and other information, which is helpful to determine the unique identification and placement position of each book.
3. Bookshelf number
In order to facilitate readers to find books, the library will assign a unique number or label to each bookshelf. These figures are usually divided by floor, area, classification number, etc. So that readers can quickly find the bookshelf they need according to the number.
4. Classification number
Each book will be given a specific classification number, which is determined according to the subject, subject and other attributes of the book. Classification numbers usually consist of letters and numbers. For example, in LCC, "Q" stands for science, "QB" stands for astronomy, and "QB5 1.3" stands for a specific subclass of astronomy.
5, subclass order
Under the same classification number, the library can further sort books according to the author's surname, alphabetical order of book titles or other sorting rules. Doing so can make it easier for readers to find books with specific authors or titles.
6. Collection quantity
The library will also consider the number of books on each shelf when shelving. Books with large branches or large circulation can be placed in a more accessible position to meet the needs of readers.
7. User feedback
The library will also adjust the way of book shelving according to readers' feedback and needs. If readers often ask the question that some books can't be found or are difficult to consult, the library may re-evaluate the shelving method and improve it.
