LANL Releases Open Source JPEG2000 Image Server


The lead article in the September/October issue of D-Lib Magazine release yesterday is on djatoka, the open source JPEG2000 Image Server from Los Alamos National Laboratory. The authors, Ryan Chute and Herbert Van de Sompel describe their effort in the article abstract:

The ISO-standardized JPEG 2000 image format has started to attract significant attention. Support for the format is emerging in major consumer applications, and the cultural heritage community seriously considers it a viable format for digital preservation. So far, only commercial image servers with JPEG 2000 support have been available. They come with significant license fees and typically provide the customers with limited extensibility capabilities. Here, we introduce djatoka, an open source JPEG 2000 image server with an attractive basic feature set, and extensibility under control of the community of implementers. We describe djatoka, and point at demonstrations that feature digitized images of marvelous historical manuscripts from the collections of the British Library and the University of Ghent. We also call upon the community to engage in further development of djatoka.

Collocating Serial Formats Via “Linking ISSN”


Earlier this week I received an e-mail from the director of the ISSN International Center announcing a session at the ALA Annual Conference in Anaheim to talk about the “linking ISSN”. Abbreviated ISSN-L, this is a new addition to the revised ISSN standard (ISO 3297, published last August) that allows for the collocation of separate ISSNs under a single ISSN-L. The ISSN standard now explicitly states that an ISSN is a unique identifier for a specific serial in a defined medium. In other words, separate ISSN should be assigned to each different medium version of a serial. The ISSN-L table brings these separate ISSNs together.

Google News Archive Search — Where Are the Links to Content from Libraries?


Extra! Extra! Read All About It! “Explore History as it Happened: Google News Now Has Archive Search” Extra! Extra!

In my imagination I can see and hear the herald of the newspaper carrier on the street corner barking out this call. Except, Kids These Days would probably decry the use of dead trees to carry stale news and already be reading it on their PDAs and text-messaging each other on their cell phones. As it is, I found out about it through a story on Search Engine Watch (also found in Wall Street Journal and the U.K. Guardian and the New York Times) which itself touted Google’s “200 Year News Archive Search.” It is a nice service; I look at it, though, and have to wonder about the changing — if not outright diminishing — role of libraries as couriers of information. After all, couldn’t links to resources from the user’s local library be included right there next to the commercial article suppliers? If they could, why aren’t they? And what does it mean that they are not?

A Known Citation Discovery Tool in a Library2.0 World


When it comes to seeking a full-text copy of that known-item citation, are our users asking “what have you done for me lately?” OpenURL has taken us pretty far when one starts in an online environment — a link that sends the citation elements to our favorite link resolver — but it only works when the user starts online with an OpenURL-enabled database. (We also need to set aside for the moment the need for some sort of OpenURL base resolver URL discovery tool — how does an arbitrary service know which OpenURL base resolver I want to use!) What if a user has a citation on a printed paper or from some other non-online form? Could we make their lives easier, too? Here is one way. (Thanks go out to Celeste Feather and Thomas Dowling for helping me think through the possibilities and issues.)
