offering a trial package for four weeks that will give anyone an 
opportunity to see how well they cover a field. They claim to 
scan over 7000 items a week, covering over 3250 journals. The 
trial price is based on one/tenth of a year's subscription, and 
ranges from $7.20 on up. A complete list of the fields of interest 
covered can be obtained from the New York address, with the price 
for four weeks, but the following might be of immediate interest: 
Computers (complete) $39.60 
Computers—Information Retrieval $12.60 
Computers—Medical and Life Sciences Application $9.00 
Computers--Physical Sciences Applications $12.60. 
DISTRIBUTED COMPUTER SYSTEMS 
MUDPIE No. 23 mentioned several current and experimental 
network systems worth keeping an eye on, and included among them 
was the DCS network, an experimental layout at the University of 
California, Irvine. I have now received a set of their publi¬ 
cations concerning the net, as listed below: 
Farber, D. J. & K. C. Larson. The systems architecture of the 
Distributed Computer System—the communications system. 
Mimeo--paper presented at the Polytechnic Institute of 
Brooklyn Symposium on Computer Networks, April, 1972. 
Farber, D. J. & K. C. Larson. The structure of a Distributed 
Computing System—Software. Mimeo—paper presented at 
the Polytechnic Institute of Brooklyn Symposium on Computer- 
Communications Networks and Teletraffic, 1972(7). 
Heinrich, F. The structure of a Distributed Computing System- 
The distributed file system. Mimeo, 13 pp. and 3 figs.

work can contact Dr. David J. Farber, Information and Computer
