Part 2 Information Gathering, Information Sources, Publishing, and Journals Primary and Secondary Literature
1
Chemical Information Sources The Gathering of Information and Classification: a. The experiment …. the calculation … the measurements … ⇒ Discovery by definition, a discovery represents original information, i.e., information that has not previously been published.
b. The discovery is described by the discoverer
(supervisor/student at university; director/research personnel/technician working with a company, etc.)
. by writing up as a manuscript and publishing as a journal paper . by presenting at a conference and publishing as a conference paper 2 . if the discovery has commercial value, the discoverer may disclose
Chemical Information Sources (cont.) The details of the discovery (the original information) appear in the journal, conference paper, patent, or dissertation The information is in the Public Domain – the information is ‘public’ – it has been ‘published’! Primary Literature is any vehicle – journal, conference paper, patent, or dissertation – which is used for publication of original information (that is, is the first to disclose the details of the discovery, calculation, measurement, etc.) 3
Chemical Information Sources (cont.) Secondary Literature is any vehicle – review journal, monograph (book by a single author), multigraph (book by multiple authors), treatise (advanced treatment of a specialized topic), encyclopedia, dictionary, textbook, handbook (of spectra, physical data, etc.), bibliographies, indexing and abstracting services (e.g. Chemical Abstracts) – for providing information which by definition is not original. • The objective of secondary literature is to repackage and reorganize the original information reported by researchers in the primary literature • Information in secondary literature is convenient to access, but may be ‘out of date’! 4
PRIMARY LITERATURE ‘Full MS’ Abstract, Introduction, Results and Discussion, and Conclusion, full details of Experimental work, and References to related work; MS may be very long – sometimes over 60 A4 typewritten pages! Supervisor and you decide to publish the work as soon as possible; write MS giving a preliminary account of the work: ‘Preliminary MS’ abbreviated Abstract, Introduction, Discussion, Conclusion, minimal details of Experimental work, some References to related work (usually 3–5 A4 pages). 5
Patents What is a patent?
an arrangement between the inventor and the state such that the inventor receives a limitedtime monopoly to exploit the invention. Patents are the most important form of publication of industrial research.
In Chemistry processes, new chemical substance, or known chemical substances including a new use, may be patented
6
Dissertations (or Thesis) Research results written into M.Sc., M.Phil. or Ph.D. thesis deposited in library At HKUST, Ph.D. thesis forwarded to University Microfilms International (UMI) for microfilming. Access online through Dissertation for abstracts, citations from theses in US, Canada, Europe, other pats of the world. Dissertations are a major form of academic publications contain information, especially experimental detail not reported elsewhere, or published in a journal, much later. 7
Technical Reports and Conference Papers Technical Reports • Usually from government or industryfunded research • often contain information before it is published in a journal – but not reviewed by referees (i.e. not ‘peer reviewed’). • some agencies (NASA, DOE) may place reports on the web. • Abstracted by Chemical Abstracts. Conference Papers • Papers presented at a conference may be ‘published’ intact • usually no experimental details • usually not peerreviewed • abstracted by Chemical Abstracts 8
SECONDARY LITERATURE Part of an article which includes similar or related areas from other journal papers in a • Review journal • Monograph (book by a single author) • Multigraph (book by multiple authors) • Treatise (advanced treatment of a specialized topic) • Encyclopedia • And so on … 9
Reviews Valuable source of information • Enhance knowledge of own area of research, provides perspective, save time • Acquire familiarity with a new area of research Reviews in journals (‘review journals’) journals which also publish primary articles monographs, multigraphs
10
Other Sources Data Collections • Secondary literature containing data on specific topics arranged for easy access • Data may be evaluated by editor before entry – ‘added value’ Examples • Dictionaries and Handbooks: classical lists of definitions, alphabetical list of compounds with data • Encyclopedias: relevant topics in alphabetical order, may be too elementary for expert • Physical data collections: spectra, m.p., b.p., thermodynamic parameters, etc. • Reactions and syntheses guides • Analytical methods • Comprehensive treatises on specialist topics 11
Chemical Abstracts: http://www.cas.org/ Represents the most effective means of accessing and organizing data – by providing abstracts of primary and secondary literature papers – world’s largest collection of chemical information!
