awareness services; retrospective searching; storage and retrieval of spectral data
and other specialized small files are under study both in batch and interactive
searching modes as well as through a combined "semi-interactive" approach. All experiments
are aimed at meeting the needs of the working research scientist in all of the
different areas of chemically related science and technology. Accordingly, a costrecovery
dissemination system is being developed into which successful services may
be "graduated" after examination in the experimental phase. This will allow continuation
of the services and their presentation to a wide range of users in the area.
9 * INTERACTIVE TUTORIAL PROGRAMS TO TEACH UNSOPHISTICATED USERS HOW TO WRITE
EFFECTIVE STRATEGY STATEMENTS FOR SEARCHING COMPUTER-STORED DOCUMENT FILES WHICH
ARE UNCONTROLLED, KEYWORD-TYPE INDEXING. Elaine Caruso, Knowledge Availability
Systems Center, University of Pittsburgh, Pittsburgh, Pa. 15213.
Versions have been created for beginning information science students who
must be capable of handling any type of search logic and for chemists who create
profiles using the more restricted logic of Chemical Abstracts type. The programs
include feedback about document count per search term, indexing for particular
documents, bibliographic citation, and faulty structure of the~ logical statement.
One version of the tutorial evaluates search results in terms of precision and
recall scores. Experience with 100+ users is detailed.
10. EXPERIENCES WITH AUTOMATED LITERATURE SYSTEMS FOR AN ACADEMIC RESEARCH GROUP.
Mary Jane Pugh, Department of Chemistry, University of Pittsburgh, Pittsburgh,
The problem of locating, storing and retrieving information related to the
research interests of a university research group in physical organic chemistry was
examined. Several current awareness systems, both automated and manual, were evaluated.
Useful references obtained from the resulting alerts were indexed by key-words
for storage and retrieval using a special modification of the NASA search system with
an IBM 7090 computer. The system was developed to handle the literature on solvent
effects in organic chemistry. It should be readily adaptable for use in many other
areas. The file is essentially unlimited in size and can easily be updated and

K. Leon Montgomery, The Knowledge Availability Systems Center, University of Pittsburgh,
Pittsburgh, Pa. 15213.
An information storage and retrieval system for solvent effects literature has
been designed for a research team in the Chemistry Department of the University of
Pittsburgh. The novelty of the system lies in the fact that it utilizes highly
sophisticated software components of other systems namely, NASA and KAS Center of
the University of Pittsburgh, to operate on its customized data base. Importance
of such systems when canned programs and exogenous datasets are readily available,
12. COMPUTER-BASED DATA STORAGE AND RETRIEVAL SYSTEMS FOR AN ACADEMIC RESEARCH
GROUP. Fred M. Jones, Department of Chemistry, University of Pittsburgh, Pittsburgh,
The problem of the organization, maintenance, and retrieval of information
from a file of research data can be simplified considerably by a highly useroriented
and relatively unsophisticated computer-based system. The small size of such
a file allows the entire contents to be updated and listed periodically according
to a few convenient ordering mechanisms. Thus there is no computer searching (although
it is possible, if desired) and the users are not separated from the file by a machine.
The coding of chemical identity can be treated by means of a numerical fragmentation
representation whose basis of classification is oriented toward the particular structural
variations of interest. Such a coding system provides a simple mechanism for
sorting and listing compounds and the associated data in an order which is intelligible
to the users. These principles have been applied to the design and implementation
of a system to handle solution calorimetry data but is applicable to data
collected in other fields. All the programs were written in FORTRAN by a chemist.
Structure coding is based largely on functionality, and the output listings are
ordered by solute and/or solvent. The cost for input, checking, sorting and listing
ismless than $.30 per entry.
13. USER ORIENTATION FOR A COMPUTER-BASED CURRENT AWARENESS SERVICE IN A UNIVERSITY
CHEMISTRY LIBRARY. Mary Jane Scott, Chemistry Library, University of Pittsburgh,
Pittsburgh, Pa. 15213.
Unlike industrial information facilities University libraries generally assume
no responsibility for carrying out information assignments for their patrons. Even
if expanded services were available many faculty members would hesitate to delegate
even a small part of their literature work to an information group. In such a situation
the greatest benefit and satisfaction from computer-based services may depend
upon the ease and success with which faculty and students can be taught to query the
files directly for themselves with only minimum help and direction from a librarian.
The Department of Chemistry at the University of Pittsburgh, as a first step in the
use of computer-based information services, began an automatic current awareness service
through its departmental library. The service was designed to allow direct
user participation to the fullest practical extent which ranged from faculty members
who sent requests in brief notes to the library, to graduate students who wrote and
coded profiles, then used the library 2741 terminal to enter the requests directly
to the University IBM/360 system. Introductory training methods and results in
searching CAS magnetic tapes will be described.
14. A COMPUTERIZED CURRENT AWARENESS SERVICE USING CHEMICALBIOLOGICAL
ACTIVITIES (CBAC). V. B. Bond, C. M. Bowman, M. T Brown.
Computation Research Laboratory, The Dow Chemical Company, Midland,
A computerized current awareness service for selective dissemination of
information using Chemical-Biological Activities (CBAC), a Chemical
Abstracts magnetic tape service, is described. The system, now three
years old, includes sixty profiles containing terms, author names, and
journal coden assigned positive or negative numerical weights relative
to an arbitrary hit level. Right truncation of terms is allowed. In
searching, the titles and abstracts from each biweekly CBAC tape are
inverted and matched against the alphabetized list of words from all
profiles. Hit documents are printed on 4 x 6" card forms. Precision
of weighted word profiles as determined by feedback data and user
reaction to abstract searching are discussed.
15.POSSIBLE NEW METHODS OF SCIENTIFIC-INFORMATION TRANSFER. F. M.
O'Hara, Jr., R. B. Parker, Oak Ridge National Laboratory, G-56,
4500-S, P. 0. Box X, Oak Ridge, Tennessee 37830.
The means of exchanging technical information will be altered in
the coming decades by the advancing technologies of communication,
microimaging, and reprography. Fractionation of TV programming, devices
built into TV sets to electronically reproduce texts of what is broadcast,
and sophisticated equipment for personal communication between
the televised speaker and his audience may allow the medium to supplement
scientific meetings for rapid disclosure of technical findings.
Microforms distributed to central depositories and machine searched;
only abstracts or article descriptors sent to subscribers; and fullsized
copies automatically reproduced, addressed, and mailed to the
requester may replace complete hard-copy versions of journals. Information
retrieval may soon be aided by video/digital tape recorders that
store documents via laser TV equipment, search them with a digital
computer, and display them on a TV screen for evaluation before printing
them out on a copying machine. Many of the current concepts of ownership
of intellectual property will have to be adjusted to accommodate
such new information-exchange capabilities.
