Readings week #5

Imaging Pittsburgh...
I found this reading to be extremely interesting since it related directly to my perspective field. This article related the challenges and issues surrounding working with different institutions as well as the challenges inherent in any digitization project. Of the most interest to me were the communications challenges the project faced. Do all the technological communication methods available lead to aceptable communication?

YouTube and libraries...
This article seemed like an advertisement for YouTube. It didn't really interest me at all. I don't have video recording equipment so I have no need to create an account. I have viewed videos on YouTube but they were for entertainment, not for instruction or training.

Data Compression
Two articles were about data compression using either lossy or lossless technology. I understand the need for compression in order to more efficiently store and transfer data. I now have some understanding of the different methods used to compress different types of data such as text, audio, and video. I also now understand that if you use a compression program to encode your data the receiver of the data must have the same program to decode the data. I am alittle concerned by lossy data compression in that the data obtained after decoding is not necessarily identical to the original. Although this method is usually used for images and audio I have to wonder if this is always the case. Who knows what text has been victimized by lossy data compression?

This was my favorite article as well. I loved reading about the soup to nuts of a successful collaborative communications project. While they had a few hurdles, they came out with a great site on time.

It was interesting to read/view the YouTube article. I found it interesting because my kids view it all the time. I read it as though we are getting another idea as a library/librarian as how to get people/kids interested in seeing what the library has to offer. If they can view it from the comforts of their rooms/home maybe they will actually come in to try it out. Sometimes not knowing how to do something makes it too scary to ask. Kind of a thinking outside of the box, if you will for the library.
