Cookies | Small pieces of information sent by Web servers and stored on your Web browser. If you revisit the site that sent the cookie, the site can read back information from the cookie (for example, what you ordered there, what preferences you set for that particular page, and so on).

Database | As used in this section, database is a name for a Web site or sites that provide access to groups of texts, whether the texts are periodical articles, books, or other kinds of documents. Thus ProQuest (see entry) can be described as an "online text database."

Keyword search | Searching a database or a search engine for a topic by using words associated with that topic. Thus, someone conducting a search for information on careers in technical communication might start by inserting "technical communication careers" into the text box of a search engine or a database. Keyword searches can be tricky because the word or words you select to identify your subject might not be those that other people would choose. When doing keyword searching, it is wise to do several searches using different keywords.

Listserv | Listserv is a registered trademark owned by L-Soft International that names the software the firm markets for creating, managing, and controlling electronic mailing lists. A mailing list is a list of names and addresses of people to who mail can be sent all at once. Listserv is just one of many pieces of software that can be used to manage such lists, but the term is often used casually (as in "I joined a new listserv today") in places where it would be more accurate to say "I joined a new electronic mailing list today."

MOO | A MUD (see next entry) that is "object-oriented," a term that refers mostly to how the computer program that runs the MUD is written. From the user's point of view, there may not be much difference between a MOO and a MUD.

MUD | A multiple user dimension, multiple user dialogue, or multiuser domain (or sometimes multiple user dungeon) is a computer program that creates a common space (thus "virtual reality") on the Web that users can log onto and explore. Each user takes control of a computerized character whose role that user plays when inside the MUD; because a MUD is text based, users type in dialogue to participate. Some MUDs are used for interactive chat rooms among people shared interests; others are used for role-playing games.
