Library Preservation


                                        Main article: Digital preservation
                   
            Digital preservation in its most basic form is a series of activities maintaining access to digital materials over time. Digitization in this sense is a means of creating digital surrogates of analog materials such as books, newspapers, microfilm and videotapes. Digitization can provide a means of preserving the content of the materials by creating an accessible facsimile of the object in order to put less strain on already fragile originals. For sounds, digitization of legacy analogue recordings is essential insurance against technological obsolescence.
             The prevalent Brittle Books issue facing libraries across the world is being addressed with a digital solution for long term book preservation. Since the mid-1800s, books were printed on wood-pulp paper, which turns acidic as it decays. Deterioration may advance to a point where a book is completely unusable. In theory, if these widely circulated titles are not treated with de-acidification processes, the materials upon those acid pages will be lost. As digital technology evolves, it is increasingly preferred as a method of preserving these materials, mainly because it can provide easier access points and significantly reduce the need for physical storage space.
        Cambridge University Library is working on the Cambridge Digital Library, which will initially contain digitised versions of many of its most important works relating to science and religion. These include examples such as Isaac Newton's personally annotated first edition of his Philosophiæ Naturalis Principia Mathematica as well as college notebooks and other papers,[ and some Islamic manuscripts such as a Quran from Tipoo Sahib's library.
         Google, Inc. has taken steps towards attempting to digitize every title with   "Google Book Search". While some academic libraries have been contracted by the service, issues of copyright law violations threaten to derail the project. However, it does provide - at the very least - an online consortium for libraries to exchange information and for researchers to search for titles as well as review the materials

Digital Reformatting

                      Digital reformatting is the process of converting analogue materials into a digital format as a surrogate of the original. The digital surrogates perform a preservation function by reducing or eliminating the use of the original. Digital reformatting is guided by established best practices to ensure that materials are being converted at the highest quality. Imaging Standards          The Library in Congress has been actively reformatting materials for its American Librery  project and developed best standards and practices pertaining to book handling during the digitization process, scanning resolutions, and preferred file formats. Some of these standards are: The use of ISO 16067-1 and ISO 16067-2 standards for resolution requirements. Recommended 400 ppi resolution for OCR ed printed text. The use of 24 bit color when color is an important attribute of a document. The use of the scanning device's maximum resolution for digita

Information technology and access to networks

Technological standards         The Internet is a multi-layered network which is operated by a variety of participants. The Internet has come to mean a combination of standards, networks, and web applications (such as streaming and file-sharing ) that have accumulated around networking technology. The emergence of the Internet coincided with the growth of a new type of organizational structure, the standards committee. Standards committees are responsible for designing critical standards for the Internet such as TCP/IP , HTML , and CSS . These committees are composed of representatives from firms, academia, and non-profit organizations. Their goal is to make decisions that advance technology while retaining interoperability between Internet components. Economists are interested in how these organizational structures make decisions and whether those decisions are optimal. The supply of Internet access         The commercial supply of Internet access began when t

Economics of Digitization

                                                                                                         Economical View              The economics of digitization is the field of economics that studies how digitization affects markets and how digital data can be used to study economics. Digitization is the process by which technology lowers the costs of storing, sharing, and analyzing data. This process has changed how consumers behave, how industrial activity is organized, and how governments operate. The economics of digitization exists as a distinct field of economics for two reasons. First, new economic models are needed because many traditional assumptions about information no longer holder in a digitized world. Second, the new types of data generated by digitization require new methods to analyze.                  Research in the economics of digitization touches on several fields of economics including industrial organization, labor economics, and inte
