ANNOTATED BIBLIOGRAPHY ON CHEMICAL DOCUMENTATION
An Interpolated Molecular Formula, A.
Feldman, Science 133, 576 (1961). The
necessity of counting hydrogen atoms
in molecular formulas may be obviated
by substituting a. "hydrogen reciprocal,"
which may be obtained more
PRESENTATION OF DATA
The Patent: Chemical Literature, A. L.
Miller, J. Patent Office Soc. 44, 13341
(February 1962). Gives examples
of a successful experiment conducted
at Esso Research and Engineering
Company in an attempt to improve the
effectiveness of the communication of
patents. The claims of several patents
are rearranged, combined, and rewritten
to result in one or more simple statements
of the invention that has been
claimed. The breadth of each part of
each aspect of the invention is added.
In each "scope" addendum, the complete
definition of the extent of the
claims is made. When necessary, information
from the specifications is
added. The overall rewrite of the
claimed invention is called a claim
REPRODUCTION OF DATA
Bibliography on Reproduction of Documentary
1961, Loretta J. Kiersky, Special
Libraries 53, 135-40 (1962). Some 40
journals are covered for articles in
this field and reported under the subject
headings: Copying Methods, Copying
Processes, Equipment, Applications,
Systems, Standards, and General.
The Interrelationship of Microfilm
Copying Devices and Information Retrieval,
Chester M. Lewis, Special
Libraries 53, 130-34 (1962). Reviews
the various copying processes and
devices, giving an estimate of cost
and applications of each. MCP
CLASSIFYING, INDEXING, CODING,
Manual for a Punched Card Retrieval
System for Organic Phosphorus Compounds,
J. Frome, M. A. Gannon, P. T.
O'Day, and F. M. Sikora, U.S. Dept. of
Commerce, Patent Office, Office of
Research and Development, Report No.
22 (Washington, D.C.) 1961. 24 pages.
The punched-card retrieval system developed
by the U.S. Patent Office for
organic-phosphorus compounds is described
as applied to the organic phosphorus
compounds in Class 260, Subclass
461. The card deck to date includes
approximately 2201 patents.
The Development of a Combination
Manual and Machine-Based Index to
Research and Engineering Reports,
Gerald Jahoda, Special Libraries 53,
74-78 (1962). Some of the steps in
the development of an indexing system
are described. This development and
the operation of the system are expensive
and the area of application of a
coordinate index should be carefully
The Use of a Collator in an Inverted
File Index, Fred R. Whaley, Special
Libraries 53, 65-73 (1962). When the
documents associated with each given
term are stored together in a unit and
these units are kept in order by term
(or its code) the system is a collating
or inverted-file system. The use of a
collator in an inverted file index is
about the least expensive machine of
either type for deep indexing. The system
in use at Linde Company is described.
Finding What's Known, E. Herbert,
International Science and Technology
1, 14-23 (January 1962). The various
devices of information retrieval, their
powers, and their limitations are reviewed.
U.S. Sources of Petroleum and Natural
Gas Statistics, M. M. Rocq, Special
Libraries Association, New York,
1961, 104 pages. $6.00. A guide to
statistical information published in
231 journals, government documents,
and society and company organs of the
petroleum and natural gas industry.
Literature Services, Anon., Science
135, 303 (1962). Bibliographic and
documentation services in biotoxicology
and natural products chemistry, including
exhaustive literature searches,
continuing current and generic searches,
and literature procurement, are available
through the World Life Research
Institute, Colton, California. KG
Chinese Abstracts, Anon., Science
135, 778 (1962). A group of Communist
Chinese abstracts in various fields of
chemistry, translated from a Soviet
publication, is available from OTS
(Order 62-11104, $1.25). KG
Survey of Technical Inquiry Records at
Thornton Research Centre, Shell Research
Limited, L. J. B. Mote and
N. L. Angel, J. Document. 18, 6-19
(1962). The records of technical inquiries
collected at Thornton over the
last decade have been surveyed. One
part examines the proportions of published
and unpublished documents
supplying the answers in the main subject
fields, and the ages and numbers
of documents provided. The second
parts is concerned with inquiries involving
petroleum products. The ratio
of published to unpublished literature
is significantly higher in the general
scientific fields than in the field of
petroleum products and appears to decrease
with increasing specialization.
New Technical Information Division
Building at Thornton Research Centre,
L. J. B. Mote, Aslib Proc. 14, 11-18
(1962). A general description, with
pictures and floor plans, of England's
newest industrial information service.
This two-story building, 110 x 50 ft,
features a 50-ft abstract bar. WAS
Disseminating Current Information,
Sandra Hocken, Special Libraries 53,
93-95 (1962). A "Daily News" is
substituted for the more customary
Library Bulletin issued at less frequent
intervals. This is a single sheet
Multilithed on both sides (1300 copies).
Items are selected by laboratory personnel,
each of whom scans one or
more periodicals at the library when
notified that the new issue has been
received. The library staff prepares
the item for the news by writing a brief
abstract or annotation if necessary.
All selected articles are microfilmed,
the films are filed in coded envelopes,
and requests are filled with printouts.
Here’s what’s next.
This issue can be searched. Note: Results may vary based on the legibility of text within the document.
