Reading notes for 9/27

Data compression websites (1 and 2)- It was really interesting to read about the Lossy and Lossless data compression types. It seems very logical to understand when one is used over the other.  One would have to use lossless for spreadsheets where you wouldn't want anything changed, (even if it took up more space).  And then use lossy for audio-visual where the eye cannot differentiate too much between the two uses(and you save space).  These practical examples from the readings really helped me understand the reasoning behind using one over another. It also makes sense that the writer and the reader of the information must both understand each others "language" in order for there to be no errors with the data interpretation.

Imaging Pittsburgh (3)-  Of all the articles we had to read this week I thought this was the most fascinating.  It really gave you the background logistics behind digitizing old photographs from multiple institutions.  The metadata data differences, the copyright troubles, the organization,and the indexing language.  This whole coordination seemed like it was a difficult yet rewarding project.  I was also glad to hear that these material were being brought together and placed online so that others could get a fuller picture into Pittsburgh's history. It would be really sad to see this piece of Pittsburgh's cultural heritage begin to start to decay before it was digitized.

Youtube and libraries it could be a beautiful relationship. (4)- I think this article is stating what most large libraries know or do, use Youtube/video.  With the exception of video directions, I think many of these libraries use video to discuss how to perform basic searches/ use library websites.  However, they may not be Youtube videos, but videos nonetheless.  And I think for a large contingent of people this is the best way to learn.  Visual aids and verbal cues really help some peoples brains to conceptualize, versus written material.  I also think that these libraries should include video directions for new first time users to help them out initially.
