Preußische Instruktionen
The so-called or PI (English: Prussian instructions) are a cataloging set of rules for libraries which was used in scientific libraries in German-speaking countries and beyond. First published in 1899, the PI were replaced by other sets of rules such as the (RAK) from the 1980s onwards, which in turn have been replaced by the Resource Description and Access (RDA) rules since 2015. History Already in 1874 (hectographed edition) and 1886 (printed edition), Karl Franz Otto Dziatzko of the University Library at Breslau had presented a set of cataloging rules under the title "", also known as "" (English: Wroclaw instructions). In there, the order of the titles was defined, but not the bibliographic recording. In 1890, the in Berlin created "instructions" that regulated the admission but not the order of entries. In 1899, a compromise arose from these two sets of instructions, resulting in the first uniform set of rules, the "" (PI). They were first published on 10 May 1899 und ...

Cataloging
In library and information science, cataloging ( US) or cataloguing ( UK) is the process of creating metadata representing information resources, such as books, sound recordings, moving images, etc. Cataloging provides information such as author's names, titles, and subject terms that describe resources, typically through the creation of bibliographic records. The records serve as surrogates for the stored information resources. Since the 1970s these metadata are in machine-readable form and are indexed by information retrieval tools, such as bibliographic databases or search engines. While typically the cataloging process results in the production of library catalogs, it also produces other types of discovery tools for documents and collections. Bibliographic control provides the philosophical basis of cataloging, defining the rules that sufficiently describes information resources, to enable users find and select the most appropriate resource. A cataloger is an individual r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Index Term
In information retrieval, an index term (also known as subject term, subject heading, descriptor, or keyword) is a term that captures the essence of the topic of a document. Index terms make up a controlled vocabulary for use in bibliographic records. They are an integral part of bibliographic control, which is the function by which libraries collect, organize and disseminate documents. They are used as keywords to retrieve documents in an information system, for instance, a catalog or a search engine. A popular form of keywords on the web are tags, which are directly visible and can be assigned by non-experts. Index terms can consist of a word, phrase, or alphanumerical term. They are created by analyzing the document either manually with subject indexing or automatically with automatic indexing or more sophisticated methods of keyword extraction. Index terms can either come from a controlled vocabulary or be freely assigned. Keywords are stored in a search index. Common words li ...

Library History
Library history is a subdiscipline within library science and library and information science focusing on the history of libraries and their role in societies and cultures. Some see the field as a subset of information history. Library history is an academic discipline and should not be confused with its object of study (history of libraries): the discipline is much younger than the libraries it studies. Library history begins in ancient societies through contemporary issues facing libraries today. Topics include recording mediums, cataloguing systems, scholars, scribes, library supporters and librarians. Earliest libraries The earliest records of a library institution as it is presently understood can be dated back to around 5,000 years ago in the Southwest Asian regions of the world. One of the oldest libraries found is that of the ancient library at Ebla (circa 2500 BCE) in present-day Syria. In the 1970s, the excavation at Ebla's library unearthed over 20,000 clay tablets ...
