Figures (graphs, maps, charts, drawings, photographs) and tables must be numbered and mentioned by this number in the text. Each should be presented on a separate page or in separate electronic file and not be incorporated in the manuscript or embedded in the electronic version.

Tables and figures should have titles or headlines. For charts, the title wording should reflect the reason for presenting the figure and not simply repeat the axes (time vs. temperature, for example).

Diagrams and illustrations need only be legible and accurate. PennWell artists will redraw most.

A very complicated figure or chart with intricate scaling, however, should be "camera-ready": reproduced with crisp lines on white background to be used as a photograph, if called for. Also, it's important to remember that large, detailed illustrations must remain legible when reduced to 7 or 4-1/4 in. in width.

Color photos—in standard 35-mm prints or slides or in electronic format (see below)—are preferable. Minimum width for prints is 3-1/2 in. Each picture or slide should be given a figure number and have a caption that explains it.

All lengthy equations should be numbered and presented in a separate equations box along with necessary nomenclature.

If possible, an article and its graphics should be submitted as attachments to one or more e-mail messages (see below for more items). Or, they may be submitted on a compact disk (CD), a 3.5-in. standard diskette, or an Iomega Zip disk. The latest version of MSWord is PennWell's preference.

If digital photographs are submitted, please provide them in .tif, .eps, .jpg, or .bmp formats with a scanned resolution of at least 250-300 dpi (color mode). PowerPoint files may also be submitted.

Inexperienced writers or those for whom English is a second language are encouraged to submit manuscripts.

PennWell editors edit only when necessary to meet our standards for style and tone. If major changes, deletions, or reorganization seem necessary, the author will be contacted before publication.

The pace of our weekly publication schedule prevents us from sending typeset proofs for author review.

Although we have requirements, we are flexible. So, if there is any question about your manuscript meeting any of them, please send it anyway.

In the final analysis, it is content, not format, that is most important.
