Archival science, or archival studies, is the study and theory of building and curating archives, which are collections of documents, recordings and data storage devices. To build and curate an archive, one must acquire and evaluate recorded materials, and be able to access them later. To this end, archival science seeks to improve methods for appraising, storing, preserving, and cataloging recorded materials. An archival record preserves data that is not intended to change. In order to be of value to society, archives must be trustworthy. Therefore, an archivist has a responsibility to authenticate archival materials, such as historical documents, and to ensure their reliability, integrity, and usability. Archival records must be what they claim to be; accurately represent the activity they were created for; present a coherent picture through an array of content; and be in usable condition in an accessible location. An archive curator is called an archivist; the curation of an archive is called archive administration. Background History Archival science emerged from diplomatics, the critical analysis of documents. In 1540, Jacob von Rammingen (1510–1582) wrote the manuscript of the earliest known archival manual. He was an expert on registries (Registraturen), the German word for what later became known as archives. Rammingen elaborated a registry for the Augsburg city council. However, since he could not attend the council meeting, he described the structure and management of the archives in writing. Although this is not the first work about archival science (Rammingen himself refers to earlier literature about record-keeping), earlier manuals were usually not published. Archival science had no formal beginning. Jacob von Rammingen's manual was printed in Heidelberg in 1571. Traditionally, archival science has involved the study of methods for preserving items in climate-controlled storage facilities. It is also the study of cataloguing and accession, of retrieval and safe handling. The advent of digital documents along with the development of electronic databases has caused the field to re-evaluate its means and ends. While generally associated with museums and libraries, the field also can pertain to individuals who maintain private collections or business archives. Archival Science is taught in colleges and universities, usually under the umbrella of Information Science or paired with a History program. A list of foundational thinkers in archival studies could include: American archivist Theodore Schellenberg and British archivist Sir Hilary Jenkinson. Some important archival thinkers of the past century include: Canadian archivist and scholar Terry Cook,
