If you do not find the term you're looking for, see Best Picks for additional glossaries.

A

Abstract - A short summary of the contents of a book, a portion of a book, or a journal or magazine article. Some computerized indexes have abstracts as well as citations. The term is also used to refer to a source which lists citations to items by subject and gives a brief summary of the item. An abstract is useful for determining if an article really suits one's needs before printing or photocopying the article.

Adobe Reader - Stand-alone program or Web browser plug-in from Adobe that lets you view a PDF (Portable Document Format) file in its original format and appearance. Adobe Reader is available free and can be downloaded from Adobe Systems Inc. at http://www.adobe.com.

ASCII - (American Standard Code for Information Interchange) - A world-wide standard for the most basic format for transferring text files between programs. Sometimes referred to as unformatted text. ASCII text does not include formatting and therefore can be exchanged and read by most computer systems.

Asynchronous Communication - Electronic communication involving messages that are sent and received at different times. E-mail is an example of asynchronous communication.

Bandwidth - Transmission capacity of a network connection; in other words, how much "stuff" you can send through a connection. Usually measured in bits-per-second (bps). A full page of English text is about 16,000 bits. A fast modem can move about 15,000 bits in one second. Full motion full screen video would require roughly 10,000 bits-per-second, depending on compression.

Baud - In common usage, the speed rate of a modem usually measured in how many bits it can send or receive per second. The term is named after J.M.E. Baudot, the inventor of the Baudot telegraph code.

Bibliography - List of citations or references pertaining to a particular subject for books, periodical articles or other materials. Bibliographies, sometimes referred to as "works cited," are often found at the end of a book or an article and list the sources used in the research project.

Bit (Binary Digit) - A single digit number in base-2; in other words, either a 1 or a zero. The smallest unit of computerized data. Bandwidth is usually measured in bits-per-second.

Boolean Operators - Words such as AND, OR, NOT that are used to combine search terms to broaden or narrow a search.

Bound Periodicals - Issues of a periodical that have been gathered and bound with a hard cover to resemble a book. In the Alvin Sherman Library, bound volumes and loose issues of periodicals are shelved together. They are shelved alphabetically by the title of the periodical on the second floor of the library.

Browser - A computer application for navigating the World Wide Web. Browsers display formatted pages and graphics, and allow users to click on hyperlinks to navigate from one Web page to another. They can also present multimedia information including sound and video that may require a browser plug-in. The most popular graphical Web browsers are Netscape Navigator and Microsoft Internet Explorer.

C

Call Number - A combination of numbers (Dewey) or numbers and letters (Library of Congress) assigned to a book to identify its subject content and used to place books in their proper places on a shelf.

Case Sensitive - Capital letters (upper case) retrieve only upper case. Most search tools are not case sensitive or only respond to initial capitals, as in proper names. It is always safe to key all lower case (no capitals) in search engines because lower case will always retrieve both upper and lower case.

Catalog - A collection of records providing information on the books, journals, and other materials in the library, as well as location information for those items. Traditional card catalogs where this information was kept on a small card, have been replaced by online catalogs, allowing users to retrieve records based on title, author, subject heading, keyword, call number and/or other access points.

CD-ROM (Compact Disc-Read Only Memory) - A laser disc on which information is stored and read via a computer.

CD-ROM Database - A computer technology which allows information to be stored on a compact disc and accessed through a microcomputer. NOTE: CD-ROM databases at NSU include those which provide access to periodical article citations, full text, and statistical data. The library has some CD-ROM databases such as PEP Archive, FC Search, etc. These can be accessed only from within the Alvin Sherman Library.

Citation - A reference to a source of information. Citations should include sufficient information for a reader to locate a copy of the item. Pertinent information might include the author, title, and source (year, volume number, issue number, page number(s), etc. Databases are electronic indexes of citations to books, articles, etc.

Cyberspace - The Internet; more loosely, the virtual space found in the online world of the Internet. The term was coined by author William Gibson in his novel Neuromancer.

D

Database - A collection of information arranged into individual records to be searched by computer. Electronic indexes such as ERIC, ABI/Inform, PsycINFO, etc., are referred to as databases.

Dewey Decimal Classification System - System used to organize books, audio, videos, and other materials in a library's collection. According to the system, each item is assigned a call number based upon the item's subject. Items are then shelved in call number order. The Dewey system is used primarily in public and school libraries. In the Alvin Sherman Library, it is used for the popular, children's and young adult collections. For more see Dewey Decimal Classification System.

Directory Search Engine - see Hierarchical/Directory Search Engine

Distance & Instructional Library Services (DILS) - A department of the Alvin Sherman Library that provides services to NSU distance students. DILS provides instruction and documentation on research methods, database searching, document delivery, etc.

Encyclopedia - A single or multi-volume reference work that provides general background on either a wide range of topics or a more specialized discipline. General encyclopedias include Encyclopedia Britannica and World Book Encyclopedia; specialized encyclopedias include Encyclopedia of Advertising, Encyclopedia of Banking and Finance, Encyclopedia of Bioethics, etc. Many encyclopedias provide bibliographic reverences and make good starting places for research.

F

Full Text - Refers to the electronic representation of a document that includes the complete text of the original document (often a book or article). Depending on the file type, full text may or may not include images and tabular information. HTML files provide the complete text and may include graphs, tables, images from the original. The original formatting and page numeration is often lost in HTML versions. PDF files provide a visual replica, or scanned copy, of the material as it was originally published in print and therefore preserve all formatting, page numeration, and original images/charts/graphs/etc.
