Contemporary Methods of Digitization

INSTEAD OF A PROLOGUE A book that had to be written. Nowadays where technology is advancing at a fast pace, it is a fact that many technologies are becoming obsolete immediately and many data, analogue and digital based on these, are becoming inaccessible and will be lost permanently. Every day a large number of photos either in the form of print or digital from legacy devices, files, videos etc. are deleted or destroyed without any substantive method of recovering them. This phenomenon occurs not only privately but also in the public sector, in companies, archives, libraries, and in almost any form where archival material exists. What is this book. This book describes a fully documented and thorough method of digitizing, archiving, and documenting material from various digital and analog sources. In order to save this material from deleting, destroying or storing it in inaccessible sources and media, and to create digital libraries with a structured, and most likely long-term, future use. What is not. You will not find historical data on file storage formats or other issues, as well as analysis of handling old devices and methods as this is not its purpose. Only information necessary to substantiate the procedures is provided. There are many versions of digitization that we face in front of us, but there are no substantial and detailed ones in Greek and even adapted to Greek reality. The book is about to fill that gap. The book was completed in 2019 after three years of research, (with some corrections and additions in 2020) and published in May, 2020.
