To work in a digital environment, you must be familiar with questions of open-access materials and reproduction rights.
'Open access', in a digital environment, means that there are no imposed barriers on accessing the content: researchers do not need to pay to access the material, nor are there legal barriers imposed on access.
Note: 'Open access' and 'open source' are not interchangeable terms. 'Open source' refers to computer software whose source code is available for anyone to study, change, or distribute. While open-access materials and open-source code arise from similar ideas about the availability of knowledge, the two terms are not to be used interchangeably.
The debate around accessibility of content has been particularly active in the past few years: as a result, more and more high-quality work is available in open-access repositories across the web. However, not all works published online are open access and not all open-access works are free for unrestrained reuse.
When reproducing and citing research materials, check the conditions of use. Let's consider two examples from Wikipedia. This image of the statue of the Man from Snowy River is published under a creative commons license that allows you to Share (copy and redistribute the material in any medium or format) and Adapt (remix, transform, and build upon the material for any purpose, even commercially). This image of the cover of novel A Little Life, however, is reproduced under Fair Use terms, which places restrictions on its re-use.
Note: 'Fair use' is an American term for copyright exception, which is why you will find it used on Wikipedia. The term in Australian law is 'Fair dealing'. The two are not precisely identical, but fair dealing includes a provision for limited use of copyrighted material for study or research. Note that fair dealing, unlike fair use, does not include a provision for republication.
Open-access material, like the photographs above, should be accompanied by readily available information about restrictions (or lack of restrictions) on use. If you cannot find this information, be cautious about using the material.
Finally, regardless of whether a work is open access or whether its use is unrestricted, you must still cite your sources when producing academic work. Make sure your exhibition includes clear and accessible links to the source of any materials.
