Types of Mechanical Document Ordering
Irrespective of how books are going to be arranged, i.e.
grouped and presented on shelves there are only three methods of
mechanical ordering of documents adopted in library practice:
• Order of accession - using a system known as ‘accession
number’ or ‘numerus currens’
• Alphabetical order - using author name letters or author
numbers
• Chronological order - using year or chronological code
