Authors should write in clear, concise English. The responsibility for all aspects of manuscript preparation rests with the authors. Extensive changes or rewriting of the manuscript will not be undertaken by the Editor. All manuscripts should be accompanied by an abstract not to exceed 200 words as well as a list of key (indexing) terms. Three to six key words or terms not in the title will assist indexers in cross indexing your article.

3. References, Abbreviations. Follow the “Harvard” style for all references, listing author(s) last names and the date in parentheses in the text. In the case of multiple authors (more than three), et. al. should be following the first author. Journal titles should be abbreviated according to the Chemical Abstracts Service Source Index, 1985. The reference list should be double spaced and alphabetized. Examples of both text usage and reference listing are as follows.

Greenhill (1984) Greenhill, W. L. 1984. Plant juices . . . juices. J. Br. Grassl. Soc. 19, 30–...Ham and Booker (1982) Ham, R. K. and Booker, T. J. 1982. Decomposition . . . lysimeter. ASCE J. Environ. Eng. Div.108 (EE2), 1147–...

Particular care should be used in preparing manuscripts involving mathematical expressions. Italic or boldface type should be clearly indicated, and Greek or unusual characters should be written plainly or explained by annotations. Simple fractional expressions should be written with a slant line rather than in the usual manner, so that only a single line of type is required.

4. Illustrations. Illustrations submitted (line drawings, halftones, photos, photomicrographs, etc.) should be clean originals or digital files. Digital files are recommended for highest quality reproductions and should follow these guidelines: 300 dpi or higher, sized to fit on journal page, EPS, TIF, or PSD format only, and submitted as separate files, not embedded in text files.

Online Only Reproduction: $225 for the first page of color; $100 per page for the next three pages of color. A maximum charge of $525 applies.

Print + Online Reproduction: $900 for the first page of color; $450 per page for the next three pages of color. A custom quote will be provided for articles with more than 4 pages of color.

6. Tables and Figures. Tables and figures should not be embedded in the text, but should be included as separate sheets or files. A short descriptive title should appear above each table with a clear legend, and any footnotes suitably identified below. All units must be included.

Figures should be completely labeled, taking into account necessary size reduction. Figure legends should be typed, double-spaced, on a separate sheet. All original figures should be clearly marked in pencil on the reverse side with the number, author's name and top edge indicated.

7. Formulas and Equations. Empirical and structural formulas and mathematical and chemical equations should be arranged to fill adequately the width of a single or double column. Subscripts and especially superscripts should be written with care and exponents should be set up in a single line. All signs such as + – = <> should be spaced, but the components of mathematical products should not be spaced.

Organic structural formulas should be submitted as copy suitable for direct photographic reproduction. Do not use structures when a simple formula will suffice. Do not use multiple lines unnecessarily. It is important in avoiding errors that all formula matter be carefully arranged and executed (preferably typewritten) with special attention to correctness of symbols, location of subscripts, superscripts, and electric charges, and the placing and close join-up of single and multiple bond lines. Use a copy of the structure in the text at the point of proper citation, but when originals are provided, group these at the end of the manuscript. All furnished art must be complete. Compound numbers and other material to appear in the copy should be lettered, not typewritten. This material will not be added to original art.

8. Proofs. Page proofs are sent to the designated author using Taylor & Francis' CATS system. They must be carefully checked and returned within 48 hours of receipt.
