When 300,000 scientific
and technological articles
are indexed each year--and
each is indexed to a depth of
approximately 50 entries --
that's subject indexing
at its finest. And it's
coming in the Fall of 1967 in
the PERMUTERM SUBJECT INDEX
to Science and Technology.
Librarians are asking for it. And ISI is delivering it-the
PERMUTERM SUBJECT INDEX 1966 to Science and Technology.
PSITM will quickly locate articles for you on the specific
or generic subjects you are interested in through this daring
new concept in subject indexing. Using the computer, like a
computer was meant to be used, ISI's exclusive Permuterm
programs index the average article to a depth of approximately
50 entries. Sample formats and details are available
now. Books will be delivered in the Fall, 1967. Wait for the
PERMUTERM SUBJECT INDEX. You and your library clientele
will be glad you did.
