Dialcom Inc., a computer software corporation with headquarters in Silver Spring, has joined forces with Data Courier Inc., a subsidiary of The Courier-Journal and Louisville Times Co., to offer an electronic news service giving Dialcom users access to articles from about 540 business-related publications.

The service, which is called ABI/INFORM, includes bibliographies and summaries of articles from English-language publications, as well as articles translated from business journals published in France, Germany, the Netherlands and Switzerland. The available subject matter, which includes accounting, auditing, financial management, real estate, insurance, advertising and marketing, is tailored to the interests of top and middle management.

The feature that makes the new information service unique, according to Data Courier marketing director Steve Arnold, is that it can deliver a weekly "personalized electronic newsletter" to computer users.

"You tell the system you're interested in energy and environmental consulting and nuclear power plants," Arnold said. "Every week the Dialcom system will search the new data that we put together and route directly to your electronic mail box the titles that pertain to your topic area."

The two companies have an arrangement by which Dialcom handles hardware and software and Data Courier provides the information.

The Dialcom system has about 30,000 users in 1,100 companies. Its electronic mail clients include Westinghouse, Eastman Kodak, Exxon, the World Bank and some congressional offices. It also has electronic mail contracts with the postal systems in England, Ireland, Switzerland and Hong Kong.
