| Project
description: Pilot project to digitise images from the State Library Heritage
Collections, followed by full scale project to continue scanning all images
from the Heritage Collections and make them available to users via the
Internet. Aim to provide improved public access to the collection. |

information: |
|
| Content: |
Photographs, 3-D objects and
paintings. |
| Digitisation policy and
priorities: |
No digitisation or online policies in
place. Approximately 1% of the entire collection is involved in this
digitisation project. 10% has already been digitised; 30% is planned to be
digitised by the end of 1998 and 60% by the end of 1999. |
| Timetable: |
1 April 1997 - ongoing |
| Budget and funding: |
It should be noted that the budget figure
quoted covers four institutions over three years. Internal and State government
funding: $A250,000-$A500,000. |
| Staff resources: |
Work to be done inhouse and in
collaboration with others. |
| Technical standards: |
3 images produced from each 35mm slide
archival image - 300dpi TIFF large internet image - 72 dpi JPEG, 600 pixels
wide thumbnail internet image - 72dpi JPEG, 200 pixels wide. Computer(s):
8500/120 PowerMAC Capturing equipment: Nikon LS1000 slide scanner Storage
devices: Hard disk for temporary storage, CD-ROM for permanent storage - HP
SuperStore CD-ROM burner. |
| Cataloguing and
indexing: |
Images are regarded as an integral part of
the library catalogue. A MARC 856 tag is added to give the Internet address of
images that have one. Cataloguing data is transferred from the library
catalogue to the web page containing the image, both as text appearing on the
page, and as Dublin Core metadata in the Head section. |
| Comments: |
Main problem was deciding on resolution to
use for archival image. Started with 600 dpi, but files produced were too large
to handle easily, so dropped to 300dpi. Decision to store on CDROM was based on
cost.
Archival quality image was the main issue: whether to keep one,
what standards to use for this image, how to store it. The lower quality web
images were not a problem as the web at the moment will only display images up
to a certain quality anyway, so the standards were set by the web itself. The
final determination of the standards for the archival image were that it be of
sufficiently high quality that the item need not be rescanned within the next
five years. The 35mm slide is regarded as the ultimate archival image for
preservation. Still to be determined - software, hardware migration path for
images in future. |
