The authors share their knowledge of electronic mail -- what it is, how it works, how it can be used by campus administrators -- and national and international academic networks -- how to get connected, how much it costs, how to use BITNET and Internet. Included are "pointers" to additional resources such as special interest group mailing lists and selected Internet-accessible library catalogs and databases. * A newcomer to data administration subscribes to several electronic mailing lists and soon learns about both current issues and knowledgeable authorities in the field ... * An administrator researching campus information security policies sends a query to an electronic mailing list and is informed of an on- line archive of such policies at a university 2,000 miles away ... * An institutional researcher needing comparative financial information for a report to the provost sends electronic mail to a list of colleagues and has useful data from around the country the following day ... * Three colleagues at different institutions collaborate on a paper, using electronic mail and networks to exchange outlines, drafts, and critiques of their work in progress from colleagues around the country; when finished a "preprint" of the paper is made available in an on-line articles archive and over a dozen requests for permission to publish are received within six weeks ... Use of electronic mail has grown rapidly in recent years, reflecting the proliferation of microcomputers and networks -- departmental and other local area networks, campus-wide networks, and inter-institutional networks. University administrators, even those in non-technical areas, are joining their computing center and faculty colleagues in making extensive use of these systems for convenient and inexpensive access to colleagues and data sources. Moreover, current and planned developments in campus and inter-campus networks promise to make these capabilities even more accessible and powerful. Those of us already using networks would benefit, of course, if more of our colleagues and their data were accessible. In addition we observe that many people currently connected are using only a small fraction of the power and resources available on the world-wide academic networks. Thus this article both introduces electronic mail and networks and provides a set of "next steps" for those who are relatively new to networking. Given the wide range of computer sophistication in the higher education community, we have tried to present concepts and recommendations in non-technical language. Networking is a fast-changing field, so some of this material may be different by the time you read or try to use it. Moreover, specific commands are for example only; you will need to consult local documentation if these commands do not work in your environment. What Is Electronic Mail? Electronic mail (or "e-mail") is a computer-based system for exchange of messages and other information, which may include textual and numeric data, computer programs, and (in some advanced systems) graphics. E-mail is one of the most common applications of time-shared computers, mainframe computer networks, and (more recently) local area networks of microcomputers; it fulfills a widespread need for rapid, easy, inexpensive communication with individuals and groups, all of whom need not be available simultaneously. Electronic mail should be distinguished from two related forms of electronic communication, voice mail and facsimile (fax). Voice mail is a computer-based system for exchanging voice messages, which can be recorded, reviewed, forwarded, filed, and retrieved from local as well as remote telephones. Such systems are especially popular among non- typists and those who travel frequently. Fax is a system for transmitting images via telephone lines; the typical fax machine is a dedicated device containing a scanner for converting printed images into digital form, a modem for sending and receiving the data, and a printer. Fax machines are extremely easy to use and have the advantage over most e-mail systems of transmitting graphics as well as text; unlike e-mail, however, the transmission is not easily manipulated on the receiving end, since most faxes produce only paper output. Although it is useful to keep these three technologies distinct conceptually, they are, in fact, merging. For example the computer workstation introduced in 1988 by NeXT, Inc. features voice mail integrated with electronic mail, and several companies have recently announced add-on hardware and software for sending and receiving fax transmissions via personal computers. How Does Electronic Mail Work? The specific implementations of electronic mail vary across many software and hardware environments, but the basic concept is a computer- enhanced memorandum: * "Date" is included automatically. * "To:" is the correspondent's computer user identification, which could be "Catherine," or "Smith," or "AYG93G." If you are sending mail to another computer, the address will commonly include both a user ID and a computer (or "node") ID, such as "Dunn@Tufts," or"IRMUFFO@VTVM1," or "Updegrove% a1.relay@upenn.edu." The last address is in the so-called "domain" style, with the suffix "edu" designating education, as opposed to commercial ("com"), military ("mil"), etc. Alternatively the memorandum could be sent to a pre-defined list, such as "managers." * "From:" is the sender's user identification, inserted automatically by the system. * "Subject:" is usually a few key words typed by the sender. Once this "header" is complete, the content of the memorandum is entered either from the keyboard or by including a previously-composed file (perhaps from a personal computer). The completed memorandum is "sent" to the recipient(s), who at some later time can issue a command (again, depending on the local system) to read, reply, delete, print, forward, or file. Reply is especially convenient, since most systems can simply reverse the "To:" and "From:" in the header. This sounds pretty simple, but what does "send" mean? If both sender and recipient are users of the same time-shared computer (or local area network file server), sending is simply storing a copy of the message on a system disk and alerting the recipient that mail has been received. In the case of a networked campus, the message may travel from the sender's IBM PC through a departmental network connected to the campus backbone network, which relays it to another departmental network where it is accessed by the recipient using an Apple Macintosh. If the correspondents are in different institutions, the message could be transmitted via the rapidly growing national and international networks. National and International Academic Networks Networks now interconnect the mainframe computers and campus networks of hundreds of colleges and universities in the U.S. and abroad. The earliest academic and research network, ARPANET, was established nearly twenty years ago by the Department of Defense to facilitate advanced research projects. Other specialized networks have been created to support specific fields -- such as computer science (CSnet), magnetic fusion energy (MFEnet), and high energy physics (HEPnet) -- and specific operating systems such as UNIX (UUCP/USENET). The largest general purpose academic network is BITNET, founded in 1981 by City University of New York and Yale, which now links over 480 American colleges and universities with a similar number in Asia, Africa, Canada (where the network is known as NetNorth), Europe (where the counterpart network is EARN), Latin America, and the Middle East (see Exhibit 1). The primary uses of BITNET are electronic mail and file transfer, with transmission speeds typically limited to 9600 bits per second (bps) over leased phone lines. (At 9600 bps, one screen full of text can be transmitted in under 2 seconds.) BITNET is governed by an independent Board of Trustees and is managed under contract by EDUCOM, which works closely with NetNorth and EARN to ensure the dependable operation of a network that connects 2,850 computers and provides "gateway" connections to numerous other networks (Exhibit 2). In September 1989, the governing bodies of BITNET and CSnet agreed to an administrative merger, under the aegis of a new Corporation for Research and Educational Networking -- CREN. The basic BITNET network services described in this article are not expected to be affected by this merger. NSFNET is a newer, higher-speed network created with support from the National Science Foundation to provide remote access to supercomputers and other resources needed for advanced academic and commercial research and development. NSFNET is a three-level network: the backbone (national trunk lines) interconnects twenty-three mid-level nets, which in turn provide connection points for over 250 campus networks (see Exhibit 3). Collectively, the NSFNET backbone, mid-level, and campus nets, plus several other interconnected networks that all use a common protocol (TCP/IP) and the domain naming convention, are often referred to as "the Internet." The NSFNET backbone provides 150 times the capacity of the typical BITNET line (1.5 million bps), to enable researchers to send large files to and from supercomputers and to support remote log-in. That is, unlike BITNET, the Internet allows users in one institution to log in to another institution's computer, which might contain a specialized database, statistical analysis program, or an on-line library catalog (see Exhibit 4). Of course, NSFNET also supports electronic mail and file transfer. Although NSFNET offers much greater communications capacity than BITNET, an even more powerful network is being proposed. The National Research and Education Network (NREN) will support communications at 3 billion bps by 1996 if leaders in education, industry, and government are successful in attracting the necessary funding for research, development, and infrastructure. NREN is essential, according to proponents including Tennessee Senator Albert Gore, to support the research and development needed for long-term American technical and corporate competitiveness. Academic support for NREN is led by EDUCOM's Networking and Telecommunications Task Force (NTTF), a group of about sixty universities. While the average university administrator may not need remote access to supercomputers, we stand to gain from any developments that improve linkages among universities. A good way to learn more about technical, economic, and political prospects for NREN is to attend the annual spring conference on networking initiatives in Washington, D.C., co-sponsored by EDUCOM's NTTF and CAUSE. Institutional Costs for Network Membership What are the costs of institutional membership in one of these networks? In the case of BITNET, current membership fees for campuses in the U.S. range from $750 to $8,000, depending on Educational and General budget; different fees apply for non-degree granting institutions and corporate research labs. Additional costs include the leased phone line to the nearest connected campus (several hundred dollars per month); 9600 bps modems at each end of the line (several thousand dollars); e- mail and interface software (from free to several thousand dollars, depending on your hardware); plus personnel to provide technical and user support. Institutions do not join the NSFNET directly, but instead join one of the mid-level networks (Exhibit 3), each of which has its own schedule of fees. In general, costs of attaching to one of these networks are higher than BITNET, because of the greater transmission speeds and complexity of the Internet. How University Administrators Use E-mail and Networks Probably the most common use of electronic mail and networks is for day-to-day communication traditionally accomplished by phone, postal service, and overnight courier. Electronic mail provides timely, convenient, and inexpensive access to colleagues (assuming that they routinely read and answer their electronic mail). Committee work, program planning, plotting strategies for dealing with government agencies, and "just keeping in touch" are typical uses of e-mail. Such communication is increasing across and among campuses, and between campuses and associations like CAUSE, EDUCOM, Association for Institutional Research (AIR), CUMREC (College and University Computer Users Conference), Society for College and University Planning (SCUP), National Association of College and University Business Officers (NACUBO), National Association of State Universities and Land Grant Colleges (NASULGC), and others. Another use of electronic mail is making data requests or conducting surveys of colleagues. Many of us have "peer" institutions with which we compare ourselves regularly or occasionally, exchanging data and policies on many subjects. The traditional way of soliciting quick responses from our peers is to make telephone calls -- with all the attendant problems of "telephone tag." Data exchanges using electronic mail have now become commonplace. A key advantage is that information has to be entered into a computer only once. (A disadvantage is that the old excuse of the survey's being "in the mail" has very little credibility!) A third application is subscribing to interest-group lists, which now number over 400 on BITNET alone. Topics range from agricultural expert systems and AIDS to yachting and yeast genetics. Some lists, like the one for data administration (DASIG), operate as open forums, wherein subscribers pose questions and problems and anyone on the list can reply, either directly to the questioner or to the entire list. Others have moderators who receive all contributions and distribute a weekly newsletter, for example AIR-L for institutional researchers and SCUPNEWS for university planners. Some newsletters, like NetMonth, which is devoted to news and commentary about BITNET, run to thirty pages and feature cover art and regular columnists. Although a few lists are closed or open only with permission of a "list owner," most are open for subscription by anyone. Since there are no charges assessed for any of the lists, it is worthwhile to try several in order to find the optimal point between too little and too much information. Exhibit 5 offers a sample of lists likely to be of interest to university administrators, and Exhibit 6 provides details of how to join a list and access other network resources. Getting "Connected" Virtually all research universities and many comprehensive universities and liberal arts colleges are already connected to BITNET and/or one of the mid-level networks on the NSFNET. If you have an account on a campus mainframe connected to one of these networks, you are probablyauthorized to use the network facilities described above. Alternatively, if your departmental local area network is part of a campus-wide network that is, in turn, connected to the larger networks, you may need nothing more than some documentation (usually available from your campus computer center) to send and receive messages nationwide. If your campus is not connected, you have two choices: find other colleagues on campus who would benefit from a network connection and lobby the powers that be, or obtain a computer account on the nearest campus with a network connection. In the second case, the payoffs you report -- and demonstrate to interested colleagues -- from your personal guest account at another institution could be instrumental in convincing the campus to join a network. To obtain a guest account at another campus for network access, contact their computer center. Most centers have standard procedures for issuing such accounts, and will inform you of charges for connect time, disk storage, etc. Depending on the rates charged and the time of day that you log in, you can expect to pay $25-$50 per month for a moderately active account. In some cases, accounts are available to academic colleagues without charge. Finally, unless you want to use that campus's public terminals, you will need a terminal or microcomputer with communications (often called "terminal emulation") software, a modem, and a phone. Lobbying appropriate administrators on your campus for a network connection will be more time consuming, but could have greater long-term rewards. For one thing, you are likely to pay less (perhaps nothing or "soft money") for an e-mail account on your own campus computer. For another, your colleagues will share the benefits of connecting to this worldwide network of colleagues, computers, and information resources. Using these Networks Even for those interested in exchanging simple e-mail with professional colleagues, the proliferation of software (terminal emulators for personal computers as well as e-mail systems) and networks is daunting. Here are some hints for getting started. First, there is no universal microcomputer communications software (although Kermit, Red Ryder, VersaTerm, and MacTerminal are in widespread use). Most campuses support one or several. Check with the computer center for the best fit between your microcomputer, your needs, and their systems and support expertise. Second, there is no universal interface to BITNET or the Internet. Even the most common mainframes -- Digital VAXes running VMS and IBM systems running VM/CMS -- have several available electronic mail systems, and some campuses make modifications or design their own. Our recommendation is to find -- and read! -- the campus documentation about e-mail and networks. Third, campus support for e-mail and networks varies widely. Some campuses provide a comprehensive guide book on computing and networking to all entering faculty, staff, and students; others seem to operate on the perverse philosophy that "real networkers don't need documentation, since it's all available on-line through the network!" The best tactic on some campuses may be to hang around the computer center and buy sodas for programmers and students until you catch on. Fourth, there is not yet a universal equivalent to the telephone white pages and directory assistance, although campuses and associations increasingly are listing e-mail addresses in printed or on-line directories, and some provide a "postmaster" account to which questions can be sent. In general, you have to call or write to colleagues to determine their network addresses. They, in turn, would benefit from your using your network address on business cards and correspondence. Fifth, although virtually all academic networks are interconnected, some require sophisticated "gateway" computers to convert their otherwise incompatible technical protocols. Fortunately one protocol is used widely in the U.S., the TCP/IP protocol originally developed for ARPANET and now the basis for the Internet. Unfortunately TCP/IP is not compatible with the emerging international standard (ISO/OSI), nor with the protocol used by BITNET. Users with access to a TCP/IP network can, however, take advantage of remote log-in, an increasingly important option. Though you need not be concerned with these underlying protocols, you may have to learn extra local tricks to send mail through certain gateways. Finally, because e-mail is a relatively new medium, network ethics and etiquette are still evolving. See Exhibit 7 for some widely accepted guidelines. Conclusion Some experts envision a worldwide academic network offering every scholar fast and convenient access to colleagues, libraries, and other information resources, experimental devices, and supercomputers. As exemplified by Apple Computer's engaging video, "The Knowledge Navigator," we can expect, in the not-too-distant future, to access data from many sources and produce reports with imbedded graphics (and voice and video if appropriate), without having to know the location or format of the data -- and we certainly won't have to worry about "protocols" and "gateways"! In the interim, university administrators would be wise to stay abreast of developments in this area. If your campus is already connected to one of the academic networks, we encourage you and colleagues in your professional association to learn how to use it effectively; if not, we urge you to take the lead in educating your colleagues about the advantages -- for effective administration as well as scholarship -- of joining the growing worldwide information community. ************************************************************************ For further reading: Arms, Caroline, ed.
