Author Guidelines


Contributions to Science publishes two kinds of articles, specialized reviews and general articles on scientifical and technological research.


Submission of manuscripts

Authors are requested to register and submit manuscripts to the journal's web site. The author is asked to upload the item and provide associated metadata or indexing information to facilitate online searching and for the journal's own use.

The author may also accompany the manuscript with supplementary files in the form of data sets, research instruments, or source texts that will enrich it while contributing to more open and robust forms of research and scholarship.


The author can track the article through the editorial process-and participate in the copy-editing and proofreading of articles accepted for publication-by logging in with the username and password provided.


Format of manuscript

All contributions should be typed, double-spaced (including references, tables, etc.) on paper not exceeding 30 cm in height (standard A4 paper is appropriate), with wide margins and one side of the page only. It is the policy of the Journal to publish in English only (authors are recommended to have the manuscript thoroughly checked and corrected before submission). The Editors will warmy appreciate co-operation of

authors in preparing papers in a manner that will facilitate the work of editing and publication. For research papers an abstract self-explanatory without reference to the text -in Catalan language, too- not exceeding 200 words should be provided. Authors must provide keywords. It is essential that the author responsible for post publication correspondence (the Corresponding author) should be identified on the



The first page of the manuscript should contain only the following:

1. Title of the paper containing keywords pertaining to the subject matter. No abbreviations should be used in the title.

2. Names (including forenames or initials) of the authors and name of the institute. If the publication originates from several institutes the affiliations of all authors should be clearly stated by using superscript numbers after the name and before the institute.

3. An abstract (in English and Catalan languages) not exceeding 200 words.

4. Full name and postal address of the author to whom all correspondence (including gallery proofs) is to be sent. Telephone and fax numbers as well as e-mail code should be included to speed up communication.

5. A list of abbreviations or acronyms used in the paper if they are not explained in the text.

6. Keywords (maximally 5), which will be used for compiling the subject index.



Tables should be compiled on separate sheets (one per page table) with a descriptive title and numbered independently of the figures using Arabic numerals in the sequence in which they occur. Every table must be referred to in the text. In the text, the position for a table is to be marked by «Table...» in the middle of an extra line. The caption must explain in detail the contents of the table. As for the table itself, it must be written so that it can be read and understood without reference to the text.

References to a table are to be handled in the same way as references

to the text (see References).



References should be indicated in the text in square brackets and listed at the end of the paper or book chapter. The list should give name(s) and initial(s) of author(s), year of publication and the exact title of the paper. For journals there should follow the title of the journal, volume number, and initial and final page numbers of article. For books there should follow the name(s) of the editor(s) (if appropriate), title of the book, the name of the publisher, the town of publication, and initial and final page numbers (if appropiate). References are to be numbered and arranged in alphabetical order.

Papers that are unpublished but have been submitted to a journal may be cited with the journal's name followed by «in press». However, this practice is acceptable only if that author has at least received galley proofs of the paper. In all other cases, reference must be made to «unpublished work» or «personal communication».



Acknowledgements as well as information regarding funding sources should be provided on a separate page and will appear at the end of the text (before References).


Figures, including photographs

Diagrams and photographs should also be submitted on separate pages at the end of the article (new page for each figure). Three copies of each figure are required. Figures should be numbered consecutively with Arabic numbers in the order of their appearance. Photographs should be fine quality, large glossy prints suitable for reproduction.

Figures should not be larger than the manuscript paper. Numbers and symbols inscribed must be large enough to be legible after reduction in size.


Nomenclature and units

Only SI units are to be used (SI = Système International d'Unités). If a data with non-SI units are to be reported, they should be put in parenthesis behind the corresponding data with SI units.


Biographical details

Each author should provide a short biography, and this should include details of affiliation, and research activities and how the research group became interested in the subject being reviewed.
