Reading Notes- Week 11 (reposted)

Reading Notes- Week 11- Im reposting the notes so my blog is somewhat in order.

1) David Hawking , Web Search Engines: Part 1 and Part 2 IEEE Computer, June 2006.

I found this article on search engines informative. I hadn’t really thought about the vast amount of space a search engine uses to be efficient. I also found it interesting that there were many different aspects of the search engine in order to make it work. For example, a politeness delay is used to prevent a crawling server from having too many requests at a time. When the article discussed duplicates, it mentioned that “sophisticated” methods were needed in some case. I wonder if these methods are not employed or just have yet to be available because of the many duplicates that can be found in a typical search. The second part of the article was more confusing to me. I didn’t completely understand how the search engine knows which documents to skip, and how it numbers different documents.

2) Shreeves, S. L., Habing, T. O., Hagedorn, K., & Young, J. A. (2005). Current developments and future trends for the OAI protocol for metadata harvesting. Library Trends, 53(4), 576-589.

This article discussed the Open Archives Initiative. This initiative works towards creating metadata standards to be used universally. The creators of the initiative had hoped that people would use the standards as well as implement others along with them. Open Language Archives Community is one such community that has extended the standards they use beyond OAI. The article discusses current developments, issues, and future developments for the OAI community. The issue of metadata formats made a lot of sense, as more formats means that there is no standard.

3) MICHAEL K. BERGMAN,  “The Deep Web: Surfacing Hidden Value”

The deep web consists of all the web pages that can not be accessed by “traditional” search engines. I was surprised by the statistic: “Eighty-five percent of Web users use search engines to find needed information.” What do the other 15 percent use to find information? I would have thought that everyone used search engines. I was also surprised that many deep websites are visited more often then some surface websites. I would think that the larger amount of traffic to the site would make it a surface site.

Muddiest Point- 11/15

I have no muddiest point for this week's lecture.

Reading Notes- Week 10

Apparently I did the readings for week 11 instead of week ten. Oops. On the bright side, I  wont have to do any readings next week! There are my notes for week 10 and I changed the other post to "Reading Notes- Week 11." Sorry that it's out of order.


1) Mischo, W. (July/August 2005). Digital Libraries: challenges and influential work. D-Lib Magazine. 11(7/8). http://www.dlib.org/dlib/july05/mischo/07mischo.html


This article about digital libraries was informative. The Digital Libraries Initiatives provided funding for improvement and implementation of digital library systems. I It is important to being working on technologies to benefit the library field. I wonder what further initiative projects have been created since this article was written in 2005. We continually are given readings about interoperability.  I guess this is an issue that we will continue to come across in our education and careers.

2) Paepcke, A. et al. (July/August 2005). Dewey meets Turing: librarians, computer scientists and the digital libraries initiative. D-Lib Magazine. 11(7/8). http://www.dlib.org/dlib/july05/paepcke/07paepcke.html


I was surprised to read that part of DLI was the "uniting librarians with computer scientists." I suppose it shouldn't be such a surprise to me, but it seems like librarians have been pretty in-tune with technological changes. Then again, it has been at least 5 years since DLI began. While many of the topics brought up in this article shouldn't be new to us, (for example: "While information accession now rests on a highly technical infrastructure, the core function of librarianship remains. The information must be organized, collated, and presented.") This article was an interesting read.


3) Lynch, Clifford A. "Institutional Repositories: Essential Infrastructure for Scholarship in the Digital Age" ARL, no. 226 (February 2003): 1-7. http://www.arl.org/resources/pubs/br/br226/br226ir.shtml


 This article on Institutional Repositories discusses the implementation of institutional repositories, as technology changes, introduced a different form scholarly communication. This article brought up topics we have been discussing in our other classes in this program. Lynch states that institutional repositories improve access for users, which seems to be true of almost any information on the web. I find it interesting that this article was written eight years ago, and publishers continue to control research publications, rather than institutions maintaining their own repositories for the most part.

Muddiest Point - 11/8

If we have posted reading notes for every lecture, including week 10, does that mean we are no longer required to post reading notes to our blog?
