PITTSFORD, NY, July 15, 1992 - Microlytics, Inc. announced today that Apple
Computer will be bundling The Random House Encyclopedia, Microlytics'
best-selling electronic encyclopedia, on Macintosh computers shipped to
the higher education market through campus resellers during the
back-to-school season.

The Random House Encyclopedia is the only electronic encyclopedia on the
market which does not require a CD-ROM device. Apple will be
electronically transferring the Encyclopedia directly to the hard disk,
prior to shipment. The Encyclopedia allows users to look up information on
virtually any subject, without having to know which entry to look in. It
greatly improves the utility of information over print, and can be used by
students to enhance the use of printed encyclopedias. For example, if a
student cannot remember the name of the philosopher of ancient Athens who
carried a lantern around at midday, searching for an honest man, they can
search for "honest" and "man," or "philosopher" and "lantern," etc., and
find "Diogenes" in seconds.

If you can't remember who said "Eureka," enter it, and you are instantly
informed that it was Archimedes, sitting in his bathtub, who first
discerned the principles of water displacement, and rose from the tub and
ran through the street, yelling "Eureka!" having forgotten to dress, and
earning his place in history. The entry for the town in Kansas is also
revealed. Entering "baseball" finds not only baseball, but 67 entries
relating to baseball, including "Hank Aaron," "Grover Cleveland," and even
"amyotrophic lateral sclerosis," better known as "Lou Gehrig's disease."

By having this tremendous power, students and teachers have access to
information at their fingertips, while they are composing papers, tests,
or just browsing. The indexes of large printed encyclopedias do not allow
this degree of cross reference and look up assistance. The Random House
Electronic Encyclopedia can help students master the art of cross
referencing and help tackle multi-volume printed encyclopedias found in
homes and libraries.

"Research done at Bell Laboratories in the 1980's demonstrated that a
printed index would have to be as large, or larger, than the printed
information being indexed, in order to provide the powerful cross
reference and concordance capability offered automatically and seamlessly
in an electronic index. This is impractical in printed form, and would be
both daunting and expensive," explained Mike Weiner, president of
Microlytics.

The powerful cross referencing and indexing capability used in the
Microlytics software program was originally developed at the Xerox Palo
Alto Research Center, which developed a search utility called "Word Nerd"
to provide automatic electronic information retrieval like that found in
The Random House Encyclopedia. Microlytics holds the exclusive license to
this powerful technology, and uses it in both its own products, and in
products it develops for software publishers and information providers, on
an OEM basis.

Microlytics has sold over 140,000 copies of The Random House Encyclopedia,
making it by far the best-selling electronic Encyclopedia on the market,
and one of the best-selling electronic books ever published. "With the
potentially large market commanded by Apple, there should be many more
licensed Random House Encyclopedia users before year end," Weiner
predicted.

The Company also publishes the Word Finder thesaurus, Strunk and White's
Elements of Style, The Berlitz Interpreter and GOfer, a text retrieval
utility.

Microlytics has an ongoing development relationship with Xerox Palo Alto
Research Center (PARC), and has developed several proprietary
technologies, including high compression text software, working with the
renowned research facility. Microlytics is a subsidiary of SelecTronics
which is 38%-owned by Xerox Corporation.
