Digital Reference Services
Digital reference (more commonly called virtual reference) is a service by which a library reference service is conducted online, and the reference transaction is a computer-mediated communication. It is the remote, computer-mediated delivery of reference information provided by library professionals to users who cannot access or do not want face-to-face communication. Virtual reference service is most often an extension of a library's existing reference service program. The word "reference" in this context refers to the task of providing assistance to library users in finding information, answering questions, and otherwise fulfilling users’ information needs. Reference work often but not always involves using reference works, such as dictionaries, encyclopedias, etc. This form of reference work expands reference services from the physical reference desk to a "virtual" reference desk where the patron could be writing from home, work or a variety of other locations.

Library
A library is a collection of materials, books or media that are accessible for use and not just for display purposes. A library provides physical (hard copies) or digital access (soft copies) materials, and may be a physical location or a virtual space, or both. A library's collection can include printed materials and other physical resources in many formats such as DVD, CD and cassette as well as access to information, music or other content held on bibliographic databases. A library, which may vary widely in size, may be organized for use and maintained by a public body such as a government; an institution such as a school or museum; a corporation; or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained and experts at finding, selecting, circulating and organizing information and at interpreting information needs, navigating and analyzing very large amounts of information with a variety of resources.

Tutor
TUTOR, also known as PLATO Author Language, is a programming language developed for use on the PLATO system at the University of Illinois at Urbana-Champaign beginning in roughly 1965. TUTOR was initially designed by Paul Tenczar for use in computer assisted instruction (CAI) and computer managed instruction (CMI) (in computer programs called "lessons") and has many features for that purpose. For example, TUTOR has powerful answer-parsing and answer-judging commands, graphics, and features to simplify handling student records and statistics by instructors. TUTOR's flexibility, in combination with PLATO's computational power (running on what was considered a supercomputer in 1972), also made it suitable for the creation of games — including flight simulators, war games, dungeon style multiplayer role-playing games, card games, word games, and medical lesson games such as ''Bugs and Drugs'' (''BND''). TUTOR lives on today as the programming language for the Cyber1 PLATO Syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XMPP
Extensible Messaging and Presence Protocol (XMPP, originally named Jabber) is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML (Extensible Markup Language), it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses. Unlike most commercial instant messaging protocols, XMPP is defined in an open standard in the application layer. The architecture of the XMPP network is similar to email; anyone can run their own XMPP server and there is no central master server. This federated open system approach allows users to interoperate with others on any server using a 'JID' user account, similar to an email address. XMPP implementations can be deve ...

Ask A Librarian
The reference desk or information desk of a library is a public service counter where professional librarians provide library users with direction to library materials, advice on library collections and services, and expertise on multiple kinds of information from multiple sources. Purpose and usage Library users can consult the staff at the reference desk for help in finding information. Using a structured reference interview, the librarian works with the library user to clarify their needs and determine what information sources will fill them. To borrow a medical analogy, reference librarians diagnose and treat information deficiencies. The ultimate help provided may consist of reading material in the form of a book or journal article, instruction in the use of specific searchable information resources such as the library's online catalog or subscription bibliographic/fulltext databases, or simply factual information drawn from the library's print or online reference coll ...

American Library Association
The American Library Association (ALA) is a nonprofit organization based in the United States that promotes libraries and library education internationally. It is the oldest and largest library association in the world, with 49,727 members as of 2021. History During the Centennial Exposition in Philadelphia in 1876, 103 librarians, 90 men and 13 women, responded to a call for a "Convention of Librarians" to be held October 4–6 at the Historical Society of Pennsylvania. At the end of the meeting, according to Ed Holley in his essay "ALA at 100", "the register was passed around for all to sign who wished to become charter members," making October 6, 1876, the date of the ALA’s founding. Among the 103 librarians in attendance were Justin Winsor (Boston Public, Harvard), William Frederick Poole (Chicago Public, Newberry), Charles Ammi Cutter (Boston Athenaeum), Melvil Dewey, and Richard Rogers Bowker. Attendees came from as far west as Chicago and from England. The ALA wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Co-browsing
Cobrowsing (short for collaborative browsing), in the context of web browsing, is the joint navigation through the World Wide Web by two or more people accessing the same web page at the same time. History of cobrowsing software Early cobrowsing was achieved by local execution of software that had to be installed on the computer of each participant. More advanced tools didn't have to be installed, but still required local execution of software or at least web-browser plug-ins, extensions, or applets. Most tools were limited to a single user that was able to navigate, while the others could only watch. Newer co-browsing solutions no longer require downloads, installations, or plug-ins. Instead, these solutions rely on peer-to-peer connections and DOM manipulation. Some tools provide very limited cobrowsing by only synchronizing the page location ( URL) of the page that should be shared. Full cobrowsing supports automatic synchronization of the browsers' state and content, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Librarian
A librarian is a person who works professionally in a library providing access to information, and sometimes social or technical programming, or instruction on information literacy to users. The role of the librarian has changed much over time, with the past century in particular bringing many new media and technologies into play. From the earliest libraries in the ancient world to the modern information hub, there have been keepers and disseminators of the information held in data stores. Roles and responsibilities vary widely depending on the type of library, the specialty of the librarian, and the functions needed to maintain collections and make them available to its users. Education for librarianship has changed over time to reflect changing roles. History The ancient world The Sumerians were the first to train clerks to keep records of accounts. ''"Masters of the books"'' or "keepers of the tablets" were scribes or priests who were trained to handle the vast amount and c ...

Instant Messaging
Instant messaging (IM) technology is a type of online chat allowing real-time text transmission over the Internet or another computer network. Messages are typically transmitted between two or more parties, when each user inputs text and triggers a transmission to the recipient(s), who are all connected on a common network. It differs from email in that conversations over instant messaging happen in real-time (hence "instant"). Most modern IM application (computing), applications (sometimes called "social messengers", "messaging apps" or "chat apps") use push technology and also add other features such as emojis (or graphical smileys), file transfer, chatbots, voice over IP, or Videotelephony, video chat capabilities. Instant messaging systems tend to facilitate connections between specified known users (often using a contact list also known as a "buddy list" or "friend list"), and can be standalone applications or integrated into e.g. a wider social media platform, or a website ...

Knowledge Base
A knowledge base (KB) is a technology used to store complex structured and unstructured information used by a computer system. The initial use of the term was in connection with expert systems, which were the first knowledge-based systems. Original usage of the term The original use of the term knowledge base was to describe one of the two sub-systems of an expert system. A knowledge-based system consists of a knowledge-base representing facts about the world and ways of reasoning about those facts to deduce new facts or highlight inconsistencies. Properties The term "knowledge-base" was coined to distinguish this form of knowledge store from the more common and widely used term ''database''. During the 1970s, virtually all large management information systems stored their data in some type of hierarchical or relational database. At this point in the history of information technology, the distinction between a database and a knowledge-base was clear and unambiguous. A databas ...
