In the article Data compression it states that the fundamental idea behind digital data compression is to take a given representation of information (a chunk of binary data) and replace it with a different representation (another chunk of binary data) that takes up less space (space here being measured in binary digits, better known as bits), and from which the original information can later be recovered. These two articles really answered the question that I have had in my mind over the past few weeks as to how all the collected information and data would be stored. Wikipedia names two types of systems one being Lossless data compression systems which can be viewed in terms of a four-stage model. And, Lossy data compression systems typically include even more stages, including, for example, prediction, frequency transformation, and quantization. Truly I was not able to grasp all of the termology and information presented in the two articles. I must take more time to go over the information to come up with questions and suggestion on how to use this information in library of today.
Imaging Pittsburgh: Creating a shared gateway to digital image collections of the Pittsburgh region, by Edward A. Galloway
It was interesting to note the way the University of Pittsburgh is digitalizing their photographic collections. More and more I am understanding the significance of doing such projects. Even though many people were displaced in the 50's with little evidence of having existed in that location the pictures tell the story. In the 50's people were putting valuables, photographs and important information and documentation into what they called time capsules to be opened up at a later date. These isolated artifacts would remain isolated and opened by individuals. The shared gateway to digital image collections of the Pittsburgh region allows many individuals at near and distant places to view collections. Not only can they view their own but others also now or in the future. This is a project that is spearheading the change from paper to electronic data.
YouTube and libraries: It could be a beautiful relationship, by Paula L. Webb
Paula Webb gives various examples as to how YouTube can be of great use to Libraries. Using videos to display different types of information in regards to your library's activities and collections is one example. I could see this working in a library. Patrons could view coming attractions to book clubs, missed workshops, and children's programs. Demonstrations on using the library could also be viewed. Branches who have their own local specialties could share their events with other library branches. I think this would be a great relationship between YouTube and libraries.
