The widespread usage of multimedia in today's society has led to the expansion of knowledge through various digital devices. Websites, such as YouTube, have given users the opportunity to share their expertise on a multitude of subjects. One such example, as provided by YouTube and Libraries: It could be a beautiful relationship, states that YouTube could be used by libraries as a means to showing instructional videos or introducing resources that are available on site. Many schools and universities have done videos, such as these, as a means to help better acquaint users with their particular library system and allow them access to help when the librarians may not be available. Digitization of photographs, films, books, articles, and more have allowed viewers to obtain a larger picture of the various people and events that were occurring at that time. The 2002 National Leadership Grant project conducted by the University of Pittsburgh allowed for the digitization of more than 7000 images from archives in the area. Because of this digitization, more users were able to access and view these images and take an in-depth analysis of what Pittsburgh was like. With the digitization of text, images, and audio, however, come the issue of data storage. One solution to this problem is by the use of data compression. Data compression would allow for more information to be stored while taking up less space. As librarians, archivists, businesses, government, etc. continue to digitize documents and resources, they must keep in mind that storage is finite. Data compression, through either lossless or lossy compression, would help to remedy some spacial issues.
