Patron-driven Acquisition
Patron-driven acquisition (PDA), also referred to as demand-driven acquisition (DDA), is a model of library collection development in which a library only purchases materials when it is clear that a patron wants them. In an ideal transaction, libraries provide the patron with access to search engines, academic databases and/or library catalogs from which the patron can request items. When certain thresholds are reached for an item (e.g., number of pages read or number of requests), the library purchases the item and delivers instant access to patrons. The library may acquire the resource permanently, or acquire a license to use the resource only at certain times or in certain ways. Since content purchased is in digital format, "PDA emphasizes collecting for and at the moment of need" instead of collecting with a long-term focus. PDA is frequently associated with e-book An ebook (short for electronic book), also known as an e-book or eBook, is a book publication made available ...

Library Collection Development
Library collection development is the process of systematically building the collection of a particular library to meet the information needs of the library users (a service population) in a timely and economical manner using information resources locally held as well as resources from other organizations. According to the International Federation of Library Associations and Institutions (IFLA), acquisition and collection development focuses on methodological and topical themes pertaining to acquisition of print and other analogue library materials (by purchase, exchange, gift, legal deposit), and the licensing and purchase of electronic information resources. Collection development involves activities that need a librarian or information professional who is specialized in improving the library's collection. The process includes the selection of information materials that respond to the users or patrons need as well as de-selection of unwanted information materials, called . It als ...

Search Engine
A search engine is a software system designed to carry out web searches. They search the World Wide Web in a systematic way for particular information specified in a textual web search query. The search results are generally presented in a line of results, often referred to as search engine results pages (SERPs). When a user enters a query into a search engine, the engine scans its index of web pages to find those that are relevant to the user's query. The results are then ranked by relevancy and displayed to the user. The information may be a mix of links to web pages, images, videos, infographics, articles, research papers, and other types of files. Some search engines also mine data available in databases or open directories. Unlike web directories and social bookmarking sites, which are maintained by human editors, search engines also maintain real-time information by running an algorithm on a web crawler. Any internet-based content that can't be indexed and searched ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academic Database
A bibliographic database is a database of bibliographic records, an organized digital collection of references to published literature, including journal and newspaper articles, conference proceedings, reports, government and legal publications, patents, books, etc. In contrast to library catalogue entries, a large proportion of the bibliographic records in bibliographic databases describe articles, conference papers, etc., rather than complete monographs, and they generally contain very rich subject descriptions in the form of keywords, subject classification terms, or abstracts. A bibliographic database may be general in scope or cover a specific academic discipline like computer science. A significant number of bibliographic databases are proprietary, available by licensing agreement from vendors, or directly from the indexing and abstracting services that create them. Many bibliographic databases have evolved into digital libraries, providing the full text of the indexed c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Catalog
A library catalog (or library catalogue in British English) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A catalog for a group of libraries is also called a union catalog. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library. The card catalog was a familiar sight to library users for generations, but it has been effectively replaced by the online public access catalog (OPAC). Some still refer to the online catalog as a "card catalog". Some libraries with OPAC access still have card catalogs on site, but these are now strictly a secondary resource and are seldom ...

E-book
An ebook (short for electronic book), also known as an e-book or eBook, is a book publication made available in digital form, consisting of text, images, or both, readable on the flat-panel display of computers or other electronic devices. Although sometimes defined as "an electronic version of a printed book", some e-books exist without a printed equivalent. E-books can be read on dedicated e-reader devices, but also on any computer device that features a controllable viewing screen, including desktop computers, laptops, tablets and smartphones. In the 2000s, there was a trend of print and e-book sales moving to the Internet, where readers buy traditional paper books and e-books on websites using e-commerce systems. With print books, readers are increasingly browsing through images of the covers of books on publisher or bookstore websites and selecting and ordering titles online; the paper books are then delivered to the reader by mail or another delivery service. With e-b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Library Management
Library management is a sub-discipline of institutional management that focuses on specific issues faced by libraries and library management professionals. Library management encompasses normal managerial tasks, as well as intellectual freedom and fundraising responsibilities. Issues faced in library management frequently overlap with those faced in managing non-profit organizations. The basic functions of library management include overseeing all library operations, managing the library budget, planning and negotiating the acquisition of materials, Interlibrary Loan LLrequests, stacks maintenance, over seeing fee collection, event planning, fundraising, and human resources. Common library construct Most of the libraries that store physical media like books, periodicals, film, and other objects adhere to some derivative of the Dewey Decimal System as their method for tagging, storing, and retrieving materials based on unique identifiers. The use of such systems have caused li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
