Digitisation is the means of converting hard-copy or non-digital records into digital format. It can involve taking digital photographs of original records or scanning (imaging) records.
There are two main categories of digitisation:
- Business process digitisation programs: the ongoing routine digitisation of records for daily business use, such as digitising mail, invoices, applications, submissions etc as they are received by the organisation.
- Back-capture digitisation projects: the retrospective digitisation of existing paper records conducted for a variety of reasons, such as to streamline systems, enable the destruction of original paper records, make records more accessible or preserve old and fragile records.
This guidance provides advice for NSW public offices on implementing sound and well structured digitisation projects and programs for records.
The guidance promotes compliance with the general retention and disposal authority for original or source records that have been copied, the Standard on Records Management and the Standard on the Physical Storage of State records.
The guidance can also help public offices to ensure:
- the reliability and authenticity, and hence the legal admissibility and credibility of digital images
- that digital images will be accessible for as long as they are required
- that strategies are in place to create digital images fit for long-term retention
- the sound management of original paper records.

Exclusions from this guidance
This guidance does not address:
- the digitisation of analogue audio or video records
- the specific issues concerning the digitisation of microfilm or microfiche (although much of the back-capture guidance is still relevant to such projects)
- the management and preservation of ‘born digital’ records
- the specific technical parameters for particular types of paper records - if your organisation requires guidance you should seek advice from digitisation computer software and hardware vendors
- systems network architecture issues relating to digitisation - your organisation should refer to its existing computer systems administration and implementation procedures.
If your organisation is intending to digitise records that are required as State archives you should refer to these guidelines but also contact State Records for further advice.
The majority of these definitions are taken from Archives New Zealand's Digitisation standard (2007). Other sources are noted after the definitions.
Back-capture digitisation projects
Retrospective or project-based digitisation of existing sets of non-digital records to enhance accessibility, maximise re-use or for preservation purposes.
Digital materials which are created and retained only in digital form, without ever having had a non-digital equivalent. This term is used to differentiate them from:
- digital materials which have been created as a result of converting non-digital originals
- digital materials which may have originated from a digital source but have been printed to paper.

Business [information] system
An automated system that creates or manages information about an organisation’s activities. Includes applications whose primary purpose is to facilitate transactions between an organisational unit and its customers eg. an e-commerce system, client relationship management system, purpose-built or customised database, finance or human resources systems. Business information systems that create or manage records should have the appropriate functionally for these tasks, or they should interface with other systems that manage the records.
[National Archives of Australia, Recordkeeping Glossary]
Business-process digitisation programs
Digitisation of records, often on receipt, and incorporation of the digital record into a business system supporting ongoing organisational activities. Such digitisation may take place in conjunction with the operation of an electronic document and records management system.
An image that has been created from another image, such as a master image, through an image editing process to create a user or working copy. The process usually involves a loss of information to reduce the size of the image by sampling it to a lower resolution, using lossy compression techniques, or altering an image using image processing techniques. Typically, such derivatives are made for purposes such as web access, including 'thumbnail' images that might be only 100 pixels square, or as 'reference' or 'service' images that should fit completely within an average monitor. Images created for this purpose commonly have smaller file sizes and, therefore, do not require a fast network connection and are in web-viewable formats.
Note: With business process digitisation, derivatives may not be necessary.
Also known as imaging or scanning, digitisation is the means of converting hard-copy or non-digital records into digital format. Digitisation may also be undertaken by taking digital photographs of the original records.
The process of establishing access points to facilitate retrieval of records and/or information.
A faithful digital reproduction of a record, optimised for longevity and for production of a range of delivery versions (derivatives). Masters are often captured at the highest practicable quality or resolution and stored for long-term usage. Typically, masters are stored in an off-line mode on tape or CD and are accessed only for the production of derivative images.
Note: With business process digitisation it is likely that only one image will be produced rather than a master and derivates.
Data describing context, content and structure of records and their management through time.
Any record made and kept, or received and kept, by any person in the course of the exercise of official functions in a public office, or for any purpose of a public office, or for the use of a public office.
[State Records Act 1998 (NSW)]
Information systems which capture, maintain and provide access to records over time.
[AS 4390-1996, Part 1, 4.20].
The process of removing or masking unwanted or sensitive areas of a record prior to showing it to others.
