Reading Notes for Week 11: Nov. 18
Digital Libraries by W. Mischo
As the title suggests the Digital Libraries article by W. Mischo listed the challenges and influential work in the field of digital libraries. It mentioned the history of federal funded support for the digital libraries initiative that began as early as 1993. It was surprising to learn that the total amount of funding was 68 million dollars, but big time government agencies like NASA, the Defense Advanced Research Projects Agency and the FBI were involved in funding the project. The influential work of the University of Illinois was mentioned as it provided the ability of viewing journal articles in a marked-up format within an internet environment, this led to web-based access to full-text journal searches.
The author hints at the competition with Google and their capabilities for “search and discovery” and academic library federated searching. To catch up, the NISO Meta Search Initiative was formed to develop industry standards for one-search access to multiple resources that will allow libraries to offer users the same search experience if they were using a web-search engine.
Dewey Meets Turing by A. Paepcke, H. Garcia-Molina, and R. Wesley
An interesting article that discusses the complex relationship between librarians and computer science. The interest in digital libraries was the harbinger to new technologies, improved search capabilities and peaked the interest of publishers. With the internet explosion and digital library initiatives, publishers saw the opportunity to raise their journal subscriptions. While the article does not explicity state that the relationship between computer science and library scientists have soured, you get the sense that its not a happy union.

Muddiest Point for Nov. 11
In terms of a search engine, is indexing and "crawling" the same thing? Please explain.
Reading Notes for Week 10: Nov. 11
Web Search Engines: Part 1 and Part 2 by David Hawking
The main point of these two articles are the nature and infrastructure of a search engine. Oddly enough the author believes that search engines should not index every web page. From what I understood indexing every page slows down the search and the probability of fetching "low-value" pages happens continuously, however, indexing has proven to be an effective strategy to find information. I did not find his arguments convincing and crawling sounds a lot like indexing to me, which leads me to Part 2 of his article.
In Part 2 he feebly attempts to explain indexing alogrithim , I got to the second paragraph and reread it over and over again. This was difficult to comprehend.
Current Developments and Future Trends for the OAI Protocol for Metadata Harvesting by Sarah L. Shreeves, Thomas G. Habing, Kat Hagerdorn, and Jeffrey A. Young
An interesting article that discusses current developments in the Open Archives Institute and its projects. For example, the Protocol for Metadata Harvesting is a tool developed by the center to facilitate interoperability between different collection standards in XML, HTTP, and Dublin Core.
