Reading notes for 10/15/2010 & 10/16/2010
1) Local Area Network: http://en.wikipedia.org/wiki/Local_Area_Network
This article describes the type of connection that many libraries have. It is important to learn about how Local Area Networks such as WiFi works. However, in some countries where the communications are not very developed, users are not able to benefit from such communication technology.
2) Computer network http://en.wikipedia.org/wiki/Computer_network
This article mentions the use of an Intranet. I was not aware of the many variables which construct the Intranet; such as internet protocols and IP based tools. This resource is vital not so much to the general public, but more for librarians in order to convey communications of information and how it happens.
3) Common types of computer networks http://www.youtube.com/watch?v=1dpgqDdfUjQ
The author outlines a new trend that local area connections are becoming more popular than wide area connections. I thought this would be quite the contrary. Perhaps local area connections are more powerful and speedy. The author mentions Ethernet as the main factor in this trend.
4) Coyle, K. (2005). Management of RFID in libraries. Journal of Academic Librarianship, 31(5), 486-489.
The author suggests that libraries will be forced via the market to utilize RFID. However, I think that RFID could be financially difficult to sustain with limited funding available for libraries. On the other hand, I learned from a conference that in Singapore, a country with transitional economy, all libraries are using RFID which has a lot of very efficient features that enable libraries to do all types of collection management activities such as inventory, self-circulation and shelving fairly easily with minimum human intervention, thus reducing the human resources costs. So, I think the market will increase, as the author mentions, over time.

Muddiest Points 10/4/2010
In the lecture, I knew that databases have some sort of tabular structure i.e. (table, row and column) and there are relations between them. I would like to ask if this structure corresponds to the (file, record and field) structure. So Table is equal to file, row equal record and column equal field; or these structures are different.

1) Database. http://en.wikipedia.org/wiki/Database
Prior to reading this article, I was under the impression that databases were simply a storage/information retrieval mechanism. However, after learning about Distributed Databases and Hypermedia Databases, there seems to be so much more. As librarians, this represents the foundation for Information Science. We need to understand and execute these systems in order to better develop knowledge organization systems based on these new database structures.
2) Anne J. Gilliland. Introduction to Metadata, pathways to Digital Information: 1: Setting the Stage http://www.getty.edu/research/conducting_research/standards/intrometadata/setting.html
In another class, I learned that Metadata is data about data. Also, there are many components to Metadata, such as, Data Value, Data Content, and Data Structure. These components of Metadata are also vital components to consider when constructing information, especially within a database structure. Understanding these components will allow librarians to better develop knowledge organization tools, and users to have a much easier time navigating a particular system.
3) Eric J. Miller. An Overview of the Dublin Core Data Model http://dublincore.org/1999/06/06-overview/
The visual aid in this article was very helpful in outlining the foundation of Dublin Core. The Dublin Core was developed for use by non-librarians and thus considered simplicity as a fundamental approach while designing Dublin Core. However, the qualified Dublin Core that uses namespaces, data format standards and controlled vocabulary will help experienced librarians to utilize it and allow users to find very specific forms of information accurately.

1) Data Compression. http://en.wikipedia.org/wiki/Data_compression
I found Data de-duplication to be interesting. Based on this information, a computer can instantaneously eliminate duplicated data. I was wondering if there is a way to manually utilize this function. I know “Defragmentation” to be a method. But, was wondering if there is a more detailed manner to find and eliminate data manually.
2) Data compression basics (long documents, but covers all basics and beyond): http://dvd-hq.info/data_compression_1.php
It seems like the main idea data compression is to store more data in a centralized location, thus reducing overall space on the hard drive. In order to do this effectively, it seems as though one would need to understand various coding techniques in order to create this type of space. Financially speaking, I think this would save libraries a lot of money if more information can be stored within fewer computers, from an administration standpoint. Also technologically speaking, data stored on public computers in libraries might not need to be changed frequently, as this would reduce a computer crashing, delay slow startups, and reduce delayed searches.
3) Edward A. Galloway, “Imaging Pittsburgh: Creating a shared gateway to digital image collections of the Pittsburgh region” First Monday 9:5 2004 http://www.firstmonday.org/issues/issue9_5/galloway/index.html
From looking at the pictures and reading the article, it looks like digital imaging is one of the prime methods of historic preservation. Unfortunately, physical copies of material found in libraries could disintegrate over time. In order to preserve the past, and more importantly, our local history, digital image collections can provide a gateway for the present to intertwine with the past, and act as a medium for a more instant and hands on look at historical artifacts. However, I think it is also important to preserve the original versions as a physical artifact to the next generations through conservation methods.
4) Paula L. Webb, YouTube and libraries: It could be a beautiful relationship C&RL News, June 2007 Vol. 68, No. 6 http://www.ala.org/ala/acrl/acrlpubs/crlnews/backissues2007/jun07/youtube.cfm
libraries will support strong marketing and outreach programs, library instructional services, and much more in the future.
