JPEG 2000 - a Practical Digital Preservation Standard? (Note: PDF)

From the Digital Preservation Coalition website

JPEG 2000 is a wavelet-based standard for the compression of still digital images. It was developed by the ISO JPEG committee to improve on the performance of JPEG while adding significant new features and capabilities to enable new imaging applications. Instead of replacing JPEG, JPEG 2000 has created new opportunities in geospatial and medical imaging, digital cinema, image repositories and networked image access. These opportunities are enabled by the JPEG 2000 feature set:
• A single architecture for lossless and visually lossless image compression
• A single JPEG 2000 master image can supply multiple derivative images
• Progressive display, multi-resolution imaging and scalable image quality
• The ability to handle large and high-dynamic range images
• Generous metadata support

Research Students in the Electronic Age: Impacts of Changing Information Behavior on Information Literacy Needs

From the Communications in Information Literacy website

Because of the rapid uptake of information and communication technology (ICT), understanding the ways in which information seeking has changed over the past decade is crucial to gaining a picture of how information literacy (IL) needs may also be changing in the electronic age. This qualitative research took an interpretivist/constructivist approach in examining the ways in which access to electronic information seeking affects the IL needs of 15 research students in an Australian university setting.
The conclusion points to enhanced roles for both supervisors and academic librarians, with the need for the latter to become perceived as educators within their university communities.
