4.1.2 Appraisal and disposal<br />

While all <strong>records</strong> need to be appraised timeously by archivists to identify those<br />

<strong>records</strong> that have archival value and thereby promote a systematic disposal<br />

programme, it is crucial for the appraisal of <strong>electronic</strong> <strong>records</strong> to take place at an<br />

early stage. Conceivably, a term<strong>in</strong>ated system of paper-based correspondence files<br />

can be appraised after the lapse of many years, because their content, structure and<br />

context will have been ma<strong>in</strong>ta<strong>in</strong>ed as part of the <strong>records</strong> themselves. In contrast, it<br />

could be very difficult to appraise a term<strong>in</strong>ated <strong>electronic</strong> system, as sufficient<br />

<strong>in</strong>formation on its function<strong>in</strong>g may not have been reta<strong>in</strong>ed and it may not even be<br />

able to be accessed, ow<strong>in</strong>g to hav<strong>in</strong>g used hardware and software which have<br />

become obsolete.<br />

Appropriate appraisal, schedul<strong>in</strong>g and disposal procedures should be applied to<br />

<strong>electronic</strong> <strong>records</strong>. If not, <strong>records</strong> needed for litigation or <strong>in</strong>vestigation purposes or to<br />

comply to an access of <strong>in</strong>formation request, might be <strong>in</strong>advertently destroyed.<br />

4.1.3 Accessibility<br />

Records, which are created by us<strong>in</strong>g the hardware and software technologies of<br />

today, should rema<strong>in</strong> available, usable, understandable and authentic over a long<br />

period of time.<br />

Inaccessibility of data is can be caused by the media and the data be<strong>in</strong>g damaged,<br />

but also by a lack of ability to read the data content on the storage media.<br />

Technology changes so rapidly that the storage media outlast the software and<br />

devices needed to read the content on the storage medium. It is not adequate to<br />

focus on the physical storage requirements for preserv<strong>in</strong>g the media optimally. One<br />

could ma<strong>in</strong>ta<strong>in</strong> the media perfectly, but there might be no way <strong>in</strong> which it could be<br />

accessed and read after the passage of time. To enable <strong>electronic</strong> <strong>records</strong> to be<br />

used over time, they must rema<strong>in</strong> readable by computer and <strong>in</strong>telligible to humans.<br />

This however, does not mean that obsolete hardware and software should be<br />

preserved along with the <strong>records</strong> to ensure access to <strong>electronic</strong> <strong>records</strong>. Rather,<br />

steps have to be taken to ensure that the <strong>records</strong> themselves are adapted or<br />

migrated to be compatible with the new systems as technological change takes<br />

place.<br />

Even though longevity of storage media is not the real issue <strong>in</strong> the management of<br />

<strong>electronic</strong> <strong>records</strong>, it is still necessary to know how to take care of the media to<br />

ensure that <strong>in</strong>formation is not lost while it is still possible to read the media with<br />

exist<strong>in</strong>g technologies.<br />
