Guide for the preparation of scientific papers for publication

Preamble

The essential aim of a scientific paper is to communicate ideas and information clearly, consisely, and honestly. Authors and edtors must keep this aim paramount. Most of the specific recommendations in this guide are directed towards this goal.

A code of good practice among scientific journals is needed to facilitate the exchange of information between scientists in all countries, especially because of the increase in the volume of scientific publications.

General recommendations

  1. Every manuscript submitted for publication in a scientific or technical journal should be accompanied by an informative abstract.

    This abstract should be drawn up in accordance with the recommendations of the "Guide for the Preparation of Authors' Abstracts for Publication".

  2. The title should be concise but as informative as possible.
    Titles of articles should be sufficiently descriptive and informative concerning their contents to be of practical use in title lists, in indexing and in coding for information storage and retrieval; abbreviations and specialist jargon should be avoided.
  3. A manuscript submitted for publication will normally be in one of the following three categories:
    1. (a) Original scientific paper, describing new research, techniques or apparatus.
      A text is regarded as belonging to the category "original scientific paper" when it constitutes a significant extension of knowledge or understanding and it is written in such a way that a qualified research worker is able, on the basis of the information given, (i) to reproduce the experiment and secure the results described with equal accuracy or within the limits of experimental error specified by the author, or (ii) to repeat the author's observations calculations or theoretical derivations and judge his findings.
    2. (b) Provisional communication or preliminary note.
      A text is regarded as a "provisional communication or preliminary note" when it contains one or more novel items of scientific information, but is insufficiently detailed to allow readers to check the said information in the ways described above. Another type of short note, generally in letter form, gives brief comments on work already published.
    3. (c) Sbuject review article.
      A subject review article is a survey of one particular subject, in which information already published is assembled, analysed and discussed. The scope of the article will depend on the journal for which it is intended.

      It is the duty of the authors of a review article to endeavour to give credit to all published work which has advanced the subject, or which would have advanced it, had it not been overlooked.

  4. Manuscripts should not be submitted for publication if they have already been published or accepted for publication elsewhere. They should not be submitted for simultaneous consideration by more than one journal.
  5. The introduction should explain the aim of the paper.
    If a historical or critical review of existing knowledge is included in a research paper, it should be confined to the immediate subject of the paper. More comprehensive reviews should be published separately as such.
  6. Authors should make clear what in the paper represents their contribution and what represents the work of others. They should be very careful to specify the limitations of their work -- the sources of error and probable error in their data, and range of validity of their concludions. They should be not make over-optimistic claims for the precision of the work, the generality of their conclusions, or the applicability of their results. They should avoid "ad hominem" arguments in criticizing other related work. Criticism should be directed only at the scintific aspects of the related work.
  7. Most journals have their own "Instructions to Authors" giving particular details of presentation to be followed. These instructions should be followed carefully. They normally cover general layout, form of bibliographical reference, symbols and abgbreviations, etc.
    Study of the format and style of similar papers on related topics in the journal to which a paper is to be sumitted may be a valuable guide to proper form and content.

    Bibliographical references should be complete. They should be presented in the style required by the journal, e.g., initials of authors, page numbers, publishers and town for book references, etc. They should specify all authors (not just the first one et al.) unless the number of authors is excessive.

  8. Material should be presented as concisely as possible in simple straightforward language, avioding words not in common use. Words appropriate to any particular subject should only be used if they have been fully accepted by other workers in the field. If it is essential to introduce new words these should be carefully defined.
    Etymologically unsound nomenclature, ambiguities, technical jargon and colloquial language should be avioded.
  9. Authors should try to make their papers reasonably self-contained by including adequate explanation and identification of symbols used.
    Authors should not use excessive non-standard abbreviations, especially of infrequently used words, since this makes papers very hard to read. Authors should check the final draft of their manucript very carefully to eliminate typographical errors, omissions of symbols and grammatical errors.

    Careless preparation of manuscripts wastes time of editors, reviewers and (if published) readers, and tends to create bias against the scientific validity of the work being reported.

    Authors who write papers in a language in which they are not completely fluent should make every effort, by consultation with colleagues who are fluent in the language, to present the work in acceptable form. It is unfair to expect either editors or referees to undertake the task of rewriting the paper to correct inadequacies of language.

  10. Should industrial or national security considerations lead to significant restriction of the amount of scientific information which can be published in the article, the text should be presented as belonging to the category 3(b) a preliminary communication, and not to 3(a) an original scientific paper. Any restriction should be clearly indicated in the paper.
  11. Explicit bibliographical reference should be made to previous work published on the same subject where this is necessary to show how the new material advances knowledge of the subject. Reference should in general only be made to fully published material or to material which has been accepted for publication.
    Reference should be brought up to date to the time of submission of the manuscript. This is especially important in the case of papers submitted for publication a long time after completion of the work reported.

    Work discussed in the text may be referred to by naming all authors, by specifying the first author et al. or by referring to the institution of group if the work of a groupe is involved. Work should not be identified by specifying the country of origin.

  12. Reference to private communications and documents with limited circulation (i.e. not available to the general scientific public) should be avoided whenever possible. Documents of a "classified" nature (company or goverment restriction) should never be referred to.
    There is no question of prohibiting allusions to conversations or private communication, but it is certainly not justified to make a statement or advance a theory based solely on a mere conversation which has not been checked.

Guide for the preparation of authors' abstracts for publication

Preamble

With the increasing amount of publication of scientific material it becomes more and more important that the basic content of all papers, long or short, published in the scientific journals should be easily available. This can be achieved by ensuring that titles are adequate and by inserting at the beginning of every article an author's abstract of the paper.

The following notes set out the main points to be considered by authors in preparing such titles and abstracts.

    General

  1. Titles of articles should be sufficiently descriptive and informative concerning their contents to be of practical use in title lists and in coding for information storage and retrieval.
  2. Every article should be preceded by an abstract (in most journals this includes Letters to the Editor).

    In writing abstracts authors should bear in mind that these may be the only parts of the papers that are read.

    The purpose of an abstract is threefold:
    (i) to help workers in the subject of the article to decide whether the contents of the paper are such that they desire to read it in full;
    (ii) to give readers for whom the paper is of "fringe" interest as much information as possible, so that it is unnecessary for them to read the whole paper;
    (iii) to expedite the work of the abstracting journals by making it possible for them to reproduce immediately the author's abstract; this will be of great assistance in the general improvement of information services in the scientific field.

    Content

  3. The abstract should contain a brief but informative summary of the contents and conclusions of the paper and should refer to any new information which it contains. The abstract should not contain information or claims not contained in the body of the paper. The abstract should not contain inessential details.
  4. The abstract should be self-contained but may refer to the title.
  5. It is valuable to indicate the treatment of various aspects of the subject by such words as "brief", "exhaustive", "theoretical", "experimental" etc. The abstract should also mention the category to which the paper belongs (cf. paragraph 3 of Guide for Preparation of Scientific Papers for Publication) when it deviates from the standard content fo the journal.
  6. New information should include observed facts, conclusions of an experiment or argument, and essential points of a new method of treatment or of newly designed apparatus, etc.
    When feasible, it is preferable to give specific numerical results rather than merely to say what was measured.
  7. Reference should be made to new material (compounds, etc.) and new numerical data, such as physical constants. Attention should be drawn to these even though they may be incidental to the main purpose of the paper
    Otherwise valuable information may be hidden.
  8. When an abstract includes experimental results there should also be some indication of the method used. Reference to new methods should include their basic principle, the range of operation and the degree of accuracy of results.
    Care should be taken to avoid distortions and misinformation. Statements of conclusions and inferences should be accompanied by an indication of their range of validity.

    Comparison with earlier results (when this is of major importance to the paper) should be as specific as possible.

    Presentation

  9. The abstract should be written to form completely connected sentences and not as a list of headings. Standard terms should be used rather than proprietary names.
    In order that the abstract can be taken over unaltered by an abstracting journal, it should not be written in the first person.
  10. It should be assumed that the reader has a general knowledge of the subject, and abstracts should be intelligible without reference to the full paper.
    The abstract should not contain non-standard abbreviations, symbols or terminology unless there is space in the abstract itself to identify them. It should not make specific references (by number) to a section, equation, figure or table of the paper.
  11. Specific references and citations should in general not be included in abstracts.
    If such reference is necessary citations to scientific journals should be made in conformity with the standard practice of the journal for which the paper is written. (The Unesco International Conference on Science Abstracting, 1949, recommended the standard proposed by the International Organization for Standardization (ISO), Technical Committee 46, names of journals being abbreviated as in the World List of Scientific Periodicals.)
  12. The abstract should be as concise as possible while fulfilling the above requirements. It should in general not exceed 200 to 250 words, and will often be much shorter.
    It may then, for example, when printed be cut out and mounted on a 7.5cm X 12.5cm card. The International Conference on Science Abstracting commended the practice of certain journals in which all the abstracts appearing in a single issue are printed together either inside the cover or with advertisements on the back in such a way that they can be cut out and mounted on index cards for reference without mutilating the pages of the journal itself. For this purpose the abstract should not be more than about 10cm wide.
  13. The International Conference on Science Abstracting recommended that abstracts be published in at least one of the more widely used languages, no matter what the original language of the paper, in order to facilitate its international usefulness.
