Week 5 - notes

Data Compression:

I never realized how much there was to data compression. I knew a little about it - for example, with audio files, I've noticed that I don't have to copy them to my computer at the highest quality for them to sound good. I didn't know about the different methods, or the difference between "lossless" and "lossy" compression (or that they even existed, really).


DVD-HQ: Data Compression Basics:

This was pretty interesting, actually. It seemed to basically be expanding on what the Wiki article said, but I enjoyed seeing some of the things illustrated - it helped me really understand how the different compression methods are done.

This article seems to show why data compression could be important to libraries. Basically, if data is compressed, and thus stored more efficiently, then there is room for more content, meaning projects such as this are easier to accomplish.


Paula L. Webb, YouTube and libraries: It could be a beautiful relationship C&RL News, June 2007 Vol. 68, No. 6 0

This was pretty basic - it just suggested a few ways libraries could use YouTube to reach the public.
