Additionally to general types of papers there is opened a new column called Oil Shale News to publish short information concerning dissertations (the title, the author, short description and the link to the printed or online paper), information on new books, on new oil shale fields, technologies, chemical factories, mines, conferences, meetings, etc. From 2011 there is also opened a new column called Historical Review to publish brief accounts or articles about investigations made earlier or information on the topic that is not generally accessible (including books), because it had been published prior to electronic capture of articles, and/or published in languages other than English. The requirements for these two types of submissions are the same as for general papers.

All correspondence concerning editorial matters (manuscript submission, reviews, etc.) should be sent to the Executive Editor by e-mail.

Manuscripts should be prepared in one of the major word processing formats as Word for Windows (other versions of Word are accepted), or Rich Text Format (RTF). For complicated formulas Equation Editor should be used. The authors are asked not to use specially defined macros. If it has been necessary to define the commands they should be added to the text file.
Electronic submission of figures: preferred file formats are TIFF, BMP, XCL, and CDR. The Editorial Office can refuse from figures presented in file formats other than described above or that have unacceptably low quality.
The text should be double-spaced on sheets of uniform size, with a 3-cm margin at the left. It is not necessary to incorporate any special page layout in the manuscript, only insert hard returns at the ends of paragraphs and headings, subheadings, lists etc. Numbering system of headings and subheadings is the following: 1.; 1.1.; 1.1.1.. Location of the tables, figures or/and illustrations should be indicated in the text in case they are provided with separate files only.

Avoid abbreviations in the title and abstract. Use standard abbreviations. The full term for which an abbreviation stands should precede its first use in the text unless it is a standard unit of measurement.
Equations should be numbered consecutively with equation numbers enclosed in parentheses at the right margin of the page. In the text, reference to an equation should be in the form of an equation number enclosed in parentheses.

Provide the illustrations by e-mail. Handwritten lettering and low-quality computer graphics are not acceptable. Line drawings for the figures should be of high contrast (600 dpi), suitable for direct reproduction. Avoid using dense shading for background. The lettering (upper- and lowercase letters, italic, bold) should follow the usage in the text. Use commas to separate units of measurement from the text. Different parts of a figure should be marked by lowercase letters. The size of symbols and lettering after reduction should not be smaller than 1.5 mm.
Plan figures to fit the proportion of the printed page (the maximum type area of the journal is 120 × 200 mm).
Figures should be provided in the original application in which they were created. Computer-generated figures should be saved as follows:

•· for Excel, save as an Excel 97 or a later version worksheet (should contain spreadsheet and embedded chart);
•· for CorelDraw, save as version 6 or a later one;
•· for Adobe Illustrator, save as TIFF or BMP files;
•· for Sigmaplot, files should be pasted into a Word document and saved as Word 97 or a later version.

Do not submit artwork/figures in colour if it is to be published in black and white. Scanned photographs and grayscale figures should be saved as TIFF files with a resolution of at least 300 dpi.
Each illustration must be clearly numbered. The appropriate place for each illustration in the text should be indicated in the margin. All illustrations must have self-explanatory legends. Print legends to illustrations on a separate sheet with double spacing and place it at the end of the paper.

Use abbreviated titles of journals in the list of references. Number references to published works consecutively and insert a numeral in the appropriate place in the text on brackets (e.g. [1]). A list of references in numerical order should appear at the end of the paper, and all references in this list should appear in the text and vice versa.
