Book classification code

Classification of documents

The books are divided into 22 categories within the "erosion control" field, and further subdivided using our own unique classification system.
Furthermore, reports, journals, audiovisual materials, university bulletins, conference minutes, etc., are represented by a separate classification number, and all classified materials are assigned individual codes (book codes) in order of publication year to further differentiate them. We strive to manage and store them systematically by shelving them in this manner.
