1. Manuscripts
The Les/Wood journal publishes  original scientific articles and review articles in the wider field of wood science and technology and related fields (see Focus and Scope).
All articles will be reviewed prior to publication. The authors are responsible for manuscript content and originality. The form and date of publication of the article are decided by the editors.

2. Peer review process
All manuscripts in Les/Wood are peer reviewed. They are examined by the editors upon receipt. Afterwards the authors are (if necessary) asked to correct or change the manuscript. After the manuscript has been corrected it is sent to two anonymous reviewers (single blind review). The reviewers receive a manuscript with the author’s name and affiliation, and the author receives the review(s) without the reviewers’ names. If the reviews require the manuscript to be corrected or augmented, the review will be sent to the author to correct the manuscript. Manuscripts with major corrections are subject to a second review. The editor-in-chief and managing editor have the right to make suggestions for improvements regarding contents and technical aspects. The article may be rejected for publication by the reviewers or editors.

3. Originality
On submitting a manuscript for publication, the authors should declare that the work submitted is original and unpublished, and is not in the process of being considered for publication at any other publisher. They should also declare that the work (either in whole or in part) will not be sent to other publishers prior to the decision of the editorial board on its publication. By submitting a manuscript to Les/Wood, as an author you agree to comply with the Publication Ethics and Malpractice Statement.

4. Scope of manuscripts
Manuscripts must be prepared in accordance with these instructions. Articles should not exceed 30,000 characters with spaces. In exceptional cases, and in agreement with the editor, articles may be longer than this.

5. Language
Les/Wood publishes scientific articles in Slovene or English. All articles have a title, abstract, keywords, chapter headings, image and table captions in both Slovene and English. Authors are responsible for the quality of the language.
Articles written in English must have a longer (one to two pages) summary in Slovene, and the articles written in Slovene must contain a longer summary in English. Authors are responsible for English and Slovene translations. The editorial board provides proofreading of Slovene texts (entire text) and English title, abstract, keywords, chapter headings, image and table captions and summary.
In the case of foreign authors, Slovene-language translation of the required bibliographic elements (title, abstract, keywords, table and figure captions, and summary) can only exceptionally and upon previous agreement be provided by the editorial board.

6. Article title
The title of the article should be brief and understandable, and should summarize the essence of the presented research. The title should be written in Slovene and English, and should not contain abbreviations or formulas.

7. Authors’ names
The title is followed by the name(s) of the author(s). For all authors we require the name, surname, institution and city with the country code. For the corresponding author, we also require contact information (address and email address).

8. Abstract
For all articles, the authors must prepare an abstract in both English and Slovene (see paragraph 5). The abstract must give concise information on the content of the article, and should not exceed 1,000 characters with spaces.

9. Keywords
The authors should provide up to eight key words in English and Slovene, and these must represent the research field covered in the article. For foreign language authors, the editorial board will take care of the translation of these into Slovene. The universal decimal classification of the article is decided by the editorial board.

10. Body of the article
The articles should have the structure of a scientific work with the following chapters, when appropriate: Introduction, Material and Methods, Results, Discussion, Conclusions, Summary, References and Appendix.
The chapters are numbered with Arabic numerals. Hierarchical levels are separated by compound numbers with a midpoint (without dots at the end of a composite number). We write the chapter headings using the same font as the rest of the manuscript (11 point).
3 HEADING 1
3.1 HEADING 2
3.1.1 Heading 3

All chapter and sub-chapter headings must be written in Slovene and English (for language details see paragraph 5). The heading References is not numbered, and the Appendices are marked with capital letters (A, B, C, ...).

11. Tables and figures
The tables should be clear and adjusted to the dimensions of the journal (A4). The font size used should not be less than 8 point. Figures (drawings, photographs, graphic images, charts, etc.) should be clear, sharp and of adequately high resolution. The positions of tables and images should be clearly indicated in the text. The number of tables and figures should be appropriate for the scope and content of the article. All captions for the tables and figures must be listed in both English and Slovene (see paragraph 5). The caption for a table is written above the table, while the caption for a figure is written below the figure. With regard to positioning, the images should be included in the text and added to the manuscript as image files in an appropriate format (please see paragraph 17).
Examples:
Table 1. Impact of tree-ring width on spruce wood density.
Figure 1. Tree rings in spruce (photo: J. Puhar).

12. Summary/Summary
Articles written in Slovene must have a longer summary in English, and articles in English must have a longer summary in Slovene (see paragraph 5). The summary should be sufficiently extensive to clearly present the topic. It must provide information on the objectives, materials and methods, results and conclusions, and should be one to two pages long.

13. Citation of the references in the text
We use the APA standard of citing to quote the references in the text and at the end (References). We quote the authors according to the following principles: one author (surname, year), e.g. (Cankar, 1984); the work of two authors (surname & surname, year), e.g. (Cankar & Prešeren, 1984); the work of more than two authors (surname et al., year), e.g. (Kovač et al., 2002). If the author's name is stated in the text, it is enough to write only the annotation year, e.g. Cankar (1984). When we cite two or more sources, they should be sorted according to the year of publication and separated by semicolons (Cankar, 1992; Žgajner et al., 1998). Standards are indicated only with the abbreviation of the standard and year of issue, for example (SIST EN 113, 1996). Legislation is referred to by the abbreviation appearing in the Official Journal, for instance (BPD 98/8 / EC, 1998).
Only publicly accessible literature should be provided. Citing internal reports, expert opinions, unpublished data, etc. should be avoided.

14. Scientific names of taxa
The scientific names of genera, species and intraspecific taxa are written in italics (Picea abies (L.) Karst.).

15. Format and form of the manuscript
The article should be written and saved in Word format (DOC or DOCX), paper size A4, margins 2.5 cm, 11-point Arial font, single line spacing, and no spaces before and after paragraphs. Additionally, the document should be saved in PDF format. For positioning, the figures should be included in the text and also sent as image files. Manuscripts with all attachments should be sent by email to katarina.cufar@bf.uni-lj.si in electronic form or submitted using the online form at https://journals.uni-lj.si/les-wood/about/submissions, by following the given instructions.

16. Graphic design
To ensure their correct position, all graphic elements should be inserted in the text by the authors. The backgrounds of charts must be white. In case of bar diagrams with only one row of columns, the columns should be white with a black border, and hatching or other forms of shading are not necessary in this case. 3D charts are to be avoided, and 2D charts used whenever possible.

17. Images

• Images taken with a digital camera must have a resolution of at least 2.1 million pixels (the width should be at least 80 mm for one column, at 300 dpi resolution).
• Images should be scanned at a resolution of 300 dpi.
• All images must be sent in the original TIFF, JPEG or equivalent format. The correct position should also be indicated in the text.
• Images that have important colour shades must be stored in the CMYK colour system and TIFF format.
• All images should be captioned in the manuscript. At the end of the caption, in brackets, the source or author should be added, e.g. Figure 1. Injuries of wood (photo: J. Puhar).
• Drawings should be made in one of the standard computer drawing programs. A minimum line thickness of 0.25 points or 0.15 mm must be used. We do not accept bad photocopies and drawings made with a pencil. If possible, avoid drawing in Word.
