86.604 is an application field and classifying system used in libraries and archives. It is an extension of the Dewey Decimal System, and it is used to classify and shelve a variety of topics, including cultural heritage materials, government documents, and audio recordings. 86.604 is designed to provide users with an efficient and logical way to browse and search for materials in any library or archive, as well as on the Internet.

The 86.604 system is based on the Dewey Decimal System, which was created in the 19th century by Melvil Dewey. The Dewey Decimal System divides knowledge into ten categories, which are then further divided into hundreds of subcategories. The 86.604 system is an evolution of the Dewey Decimal System, and it extends it by adding four additional categories to the original ten. The additional categories are Education, History, Language and Literature, and Science and Technology.

Each of these categories is then divided into four-digit codes, known as “seasons”, which indicate the topic of the material. Each four-digit code is further divided into five-digit codes, known as “subjects”. For example, 86002 is the code for “computers”, and 86017 is the code for “language and literature”. The five-digit codes are further divided into six-digit codes, known as “descriptors”, which are used to indicate more specific topics. For example, 860147 is the code for “literature written in English”.

The 86.604 system is used to catalog and classify materials in a wide variety of libraries and archives, including public, school, and university libraries. The 86.604 system is also used to categorize materials found on the Internet, such as websites and blogs.

The working principle of the 86.604 system is based on the Dewey Decimal System but it has been extended and improved upon. It is an alphabetical system, which means that items are shelved and categorized according to the first letter of the title or title word. This makes it much easier to find materials in large collections, as they are easy to locate by the their title or author name. Furthermore, the 86.604 system is designed to ensure that materials are readily available to patrons. The system makes it easy to locate materials by their subject, season, or descriptor.

In addition to being a library and archive classification system, the 86.604 system is also used in the field of research. Researchers can use the system to quickly locate materials related to their field. The system is a great tool for identifying sources on a particular topic, as researchers can easily browse through all the categories and subcategories to find related materials.

Overall, 86.604 is an effective application field and classification system used in libraries and archives as well as in the field of research. It is an evolution of the Dewey Decimal System, which provides users with an efficient way to browse and search for materials. Additionally, it makes it easy for researchers and patrons to identify and locate materials by their subject, season, and descriptor.
