HyTelnet (sometimes rendered Hytelnet or HYTELNET) was an early attempt to create a universal or at least simpler interface for the various Telnet-based information resources available before the World Wide Web. It was first developed in 1990 by Peter Scott, then at the University of Saskatchewan in Saskatoon, Canada. Using a client written by Earl Fogel, HyTelnet offered its users a primitive terminal-based GUI that allowed them to browse a directory of Telnet-based resources and then access them in a relatively standardized manner. On-line help was available, and there were frequent updates made available to its database which sites could download.
HyTelnet's chief inadequacy was that it was not centralized, i.e., every HyTelnet installation used its own separate copy of the master directory. While beneficial early-on, as it ensured no dependence on a central server, HyTelnet's user experience could vary widely as local installations might not have the same version of the client or might have obsolete information. This became a greater liability as more institutions had reliable, "always-on" Internet access. Finally, when the World Wide Web gained pre-eminence, many of the services that HyTelnet pointed to were gradually retired, increasingly limiting its relevance. HyTelnet's final database update was in 1997.
Interface
This is a typical HyTelnet screen running much as a user would have experienced it, rendered in non-proportional font to simulate a terminal. This is from one of the last releases of the client, which was version 6.9.

Items in angle brackets < > are selectable, and can be highlighted by using the cursor motion keys. There is a prominent online help option. The right arrow/cursor key selects the highlighted option, or ENTER/RETURN. The left key allows users to back up to an earlier level.
The search option allows a simple search of a central INDEX file. This INDEX file is one-line-per-resource, and is a flat file that the Hytelnet client searches directly. After entering a term, the client returns a new menu with the list of selectable items, for example this query "library":
<SITES1> On-Line Library Catalogs <PL008> National Library of Poland (Biblioteka Narodawa) <HU007> Hungarian National Library <BE004> Faculty of Agriculture Library - Gembloux <BE010> Royal Library Albert I (Belgium) <TW004> National Central Library <TW013> Taiwan Provincial Library at Taichung <DK001> Danish National Library of Science and Medicine <DK002> Royal Danish Library <DK007> Denmark's Technical Library <DK012> Danish Veterinary and Agricultural Library (AGROLINE) <IT009> Vatican Library (Biblioteca Apostolica Vaticana) <US200> Washington University in St. Louis Medical Library <US202> Waterways Online Library Facilities <US215> New York State Library <US227> University of Texas at Austin Tarlton Law Library (TALLONS) <US229> Boston Library Consortium Union List of Serials <US251> University of California Northern Regional Library Facility <US256> University of Miami Medical Library <US258> OhioLink: Ohio Library and Information Network <US266> University of Virginia Health Sciences Library <US268> Abilene Library Consortium (Texas) <US285> University of Alabama, Birmingham, Lister Hill Health Sciences Library—press space for more --
The user may then select one of these options, or go back with the left arrow. Search results will vary based on the locally installed database.
After drilling down to a specific resource, HyTelnet will display a connect page. The hostname, IP address and contact address are for example purposes only, and may not necessarily connect to anything functional (although this is a real entry in HyTelnet's last released database).
University of California (MELVYL) telnet melvyl.ucop.edu or 192.35.222.222 When asked for terminal type, enter VT100 or HELP for other options Press RETURN when prompted to To exit, type END Contact: preferred address: MELVYL System User Services melvyl@dla.ucop.edu
At this point, the user could select the "telnet" portion and attempt to connect to the remote host over Telnet. Instructions for using the resource are given. Additional instructions for general types of library and research systems were also given in HyTelnet, such as this one for INNOPAC, a common library electronic card cataloguing database:
Using INNOPAC INNOPAC is very easy to use. Just press the letter or number next to the item that you want. There is no need to press the ENTER or RETURN key when choosing one of the menu options. For example: Title searches: To search for a particular title, select T on the main menu. Author searches: To search for a particular author, select A on the main menu. Subject searches: To search for a particular subject, select S on the main menu. Keyword searches: Either "k" or "w" (varies from system to system) as listed on the menu. Other search options: Different INNOPAC libraries have added additional search options, such as Medical Subject Headings, Call Number, SuDocs numbers, Reserve Lists, etc. Popular options available when looking at any one record include: S > Show items with the SAME SUBJECT Z > Show items nearby on the shelf
The regular updates not only updated the list of resources, but also the help files in addition.
Modern implementations
The HyTelnet client is no longer maintained, but there are several web-based re-creations available.
HYTELNET on the World Wide WebArchived 2007-09-27 at the Wayback Machine is the official implementation by default, as it is Peter Scott (the original author)'s own work at his Northern Lights Internet site. This is a simple reconstruction of the HyTelnet database, converted into flat HTML files suitable for any Web browser. There is also a simple search facility.
The Floodgap Hytelnet-HTTP Museum Gateway is a variation that attempts to mimic the look and feel of HyTelnet in a web browser, using non-proportional fonts and a similar navigational style (although now point-and-click because it is running in a browser). It enhances the experience slightly with JavaScript, although it offers versions for older browsers and an "ultra-classic" view to best simulate the old interface. It also has a simple search facility. Unlike the original HyTelnet, this implementation will attempt to verify remote hosts, and will also present possible Web-based alternatives to their databases.
A context menu is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which the menu belongs. Usually the available choices are actions related to the selected object. From a technical point of view, such a context menu is a graphical control element.
The Gopher protocol is a communication protocol designed for distributing, searching, and retrieving documents in Internet Protocol networks. The design of the Gopher protocol and user interface is menu-driven, and presented an alternative to the World Wide Web in its early stages, but ultimately fell into disfavor, yielding to HTTP. The Gopher ecosystem is often regarded as the effective predecessor of the World Wide Web.
Telnet is a client/server application protocol that provides access to virtual terminals of remote systems on local area networks or the Internet. Telnet comprises of two components: (1) the protocol itself which specifies how two parties to communicate and (2) the software application that provides the service. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP). Telnet was developed in 1969 beginning with RFC 15, extended in RFC 855, and standardized as Internet Engineering Task Force (IETF) Internet Standard STD 8, one of the first Internet standards. Telnet transmits all information including usernames and passwords in plaintext so it not recommended for security-sensitive applications such as remote management of routers. Telnet's use for this purpose has waned significantly in favor of SSH. Some extensions to Telnet which would provide encryption have been proposed.
A website is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. As of December 2022, the top 5 most visited websites are Google Search, YouTube, Facebook, Twitter, and Instagram.
HCL Notes and HCL Domino are the client and server, respectively, of a collaborative client-server software platform formerly sold by IBM, now by HCL Technologies.

File Explorer, previously known as Windows Explorer, is a file manager application that is included with releases of the Microsoft Windows operating system from Windows 95 onwards. It provides a graphical user interface for accessing the file systems. It is also the component of the operating system that presents many user interface items on the screen such as the taskbar and desktop. Controlling the computer is possible without Windows Explorer running.
The Windows logo key is a keyboard key which was originally introduced on the Microsoft Natural keyboard in 1994. This key became a standard key on PC keyboards. In Windows tapping the key brings up the start menu. Ctrl+Esc performs the same function, in case the keyboard lacks this key.
JRiver Media Center is a multimedia application that allows the user to play and organize various types of media on a computer running Windows, macOS, or Linux operating systems.
In computing, a news aggregator, also termed a feed aggregator, feed reader, news reader, RSS reader or simply an aggregator, is client software or a web application that aggregates syndicated web content such as online newspapers, blogs, podcasts, and video blogs (vlogs) in one location for easy viewing. The updates distributed may include journal tables of contents, podcasts, videos, and news items.
Melvyl was the name of the online catalog of the University of California's library system. The Melvyl union catalog was produced by the California Digital Library — a unit within the department of Academic Planning, Programs, and Coordination at the UC Office of the President in downtown Oakland, California. Melvyl was named after Melvil Dewey, the library pioneer who invented the Dewey Decimal System. Melvyl was supported by the OCLC's WorldCat Local platform, which was retired in July 2021.
Compared with previous versions of Microsoft Windows, features new to Windows Vista are very numerous, covering most aspects of the operating system, including additional management features, new aspects of security and safety, new I/O technologies, new networking features, and new technical features. Windows Vista also removed some others.
The Windows shell is the graphical user interface for the Microsoft Windows operating system. Its readily identifiable elements consist of the desktop, the taskbar, the Start menu, the task switcher and the AutoPlay feature. On some versions of Windows, it also includes Flip 3D and the charms. In Windows 10, the Windows Shell Experience Host interface drives visuals like the Start Menu, Action Center, Taskbar, and Task View/Timeline. However, the Windows shell also implements a shell namespace that enables computer programs running on Windows to access the computer's resources via the hierarchy of shell objects. "Desktop" is the top object of the hierarchy; below it there are a number of files and folders stored on the disk, as well as a number of special folders whose contents are either virtual or dynamically created. Recycle Bin, Libraries, Control Panel, This PC and Network are examples of such shell objects.
In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats. All modern web browsers include bookmark features. Bookmarks are called favorites or Internet shortcuts in Internet Explorer and Microsoft Edge, and by virtue of that browser's large market share, these terms have been synonymous with bookmark since the First Browser War. Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization. In addition to bookmarking methods within most browsers, many external applications offer bookmark management.
The Yahoo! User Interface Library (YUI) is a discontinued open-source JavaScript library for building richly interactive web applications using techniques such as Ajax, DHTML, and DOM scripting. YUI includes several core CSS resources. It is available under a BSD License. Development on YUI began in 2005 and Yahoo! properties such as My Yahoo! and the Yahoo! front page began using YUI in the summer of that year. YUI was released for public use in February 2006. It was actively developed by a core team of Yahoo! engineers.

EGroupware is free open-source groupware software intended for businesses from small to enterprises. Its primary functions allow users to manage contacts, appointments, projects and to-do lists. The project releases its software under the terms of GNU General Public License (GPL).
A single-page application (SPA) is a web application or website that interacts with the user by dynamically rewriting the current web page with new data from the web server, instead of the default method of a web browser loading entire new pages. The goal is faster transitions that make the website feel more like a native app.
