When a manuscript is submitted, it is assumed that no similar paper has been or will be submitted for publication elsewhere or has been previously published. Further, it is understood that all authors listed on a manuscript have agreed to its submission. Experts will be consulted regarding the acceptability of the submission for publication in Philippine Science Letters (PSL). The Editor in charge of the submission will have the final decision regarding its acceptance. The complete list of submission requirements can be found in the Publication Ethics and Malpractice Statement.
Authors should provide the names and (e-mail) addresses of at least three possible referees.
To facilitate review, it is encouraged that the manuscript have line numbers.
Manuscripts should be organized in the following manner:

|Title||The Title (only the first word and proper names should be capitalized) should be informative and be no more than 120 characters in length. Acronyms and abbreviations should be avoided.|
|Abstract||Not necessary for Letters to the Editor, or Reports of Meeting Proceedings. The Abstract should be a single paragraph not exceeding 500 words and devoid of any references or citations. It should give the importance and objectives of the study, the general methods used, the most important results obtained, the conclusions made and their significance.|
|Keywords||5-8 key topics in the manuscript including 1-2 on general field of science|
|Text||Length and organization depends on the type of paper. The Text portion of Regular Research Article should have: Introduction, Materials and Methods, Results and Discussion, and Conclusion (optional). The Materials and Methods section may be subdivided into several subsections with concise subheadings in boldface. Sufficient detail should be provided so that findings may be replicated. The Results and Discussion sections can have subsections. The organization of the Text in a Review, Commentary, Letter to the Editor, or Report of Meeting Proceedings is at the discretion of the author(s).|
A Model is a conceptual, logical, objective or visual representation of a phenomenon or an empirical observation. The Text portion of a Modelling article should provide a brief introduction to the phenomenon or observation being modeled, and describe how the model was generated, evaluated and simulated based on known facts or preliminary data.
A Hypothesis is a theoretical attempt to explain a phenomenon or an experimental observation. The Text portion of a Hypotheses article should provide a brief introduction to the phenomenon or observation, describe a plausible explanation supported by known facts or preliminary data, and end with a suggestion as to how the hypothesis could be tested.
|Acknowledgements||Funding Agency, Collaborating Institutions, and Sources of Data. The Acknowledgements section should include all sources of financial support.|
|Conflicts of Interest||Indicate if there is none. The authors must disclose any financial, personal, or professional relationship with other individuals or organizations that could be construed as conflict of interest.|
|Contributions of Individual Authors||If more than one author. The authors must indicate in general terms the contribution or role of each author in the study.|
The following rules should be observed when citing a reference in the text:
The Reference list should be ordered alphabetically. Include the names of all the authors of each reference.
Unpublished Observations or Personal Communications:
Further, together with the manuscript, authors should submit a complete list of all references/citations as they appear in the text, e.g.,
The above list should be followed by a sorted/alphabetized list, e.g.,
The alphabetized list should match the list of references in the manuscript. This is to facilitate copy editing and checking that the references cited in the text are found in the list of references and vice versa.
|Tables||with table numbers and descriptive titles. See Making Tables. Tables should be placed at the end of the manuscript. Each table should have an informative title placed at the top. Abbreviations, footnotes, and other details should be placed below the table. Tables should be submitted as an editable version.|
|Figures||with figure numbers and appropriate captions See Making Figures. Figures should be placed at the end of the manuscript and should be "camera-ready" and of high quality. Related figures should be combined and labeled as A, B, C, etc.; captions should be Figure 1. ... (A) ..., (B) ..., (C) ..., etc. Each figure should have an informative caption placed below the figure. Only high resolution images should be used (300 dpi and above). Graphs should be saved as a scalable vector image. The figure could occupy either 1 column width (92 mm) or 2 column widths (190 mm) of the page. The height of a figure should not exceed 234 mm.|
The corresponding author should respond point-by-point to all the comments made by each reviewer in a separate letter and indicate how the manuscript was revised (or not) in response to each comment. The revised manuscript and letter addressing all the concerns of the reviewers should be sent to the editor-in-charge in a timely manner.
