Background Information on This Digital Publication

This publication contains raw and interpreted data, map images, and other graphic displays linked to research on the New Albany Shale petroleum system. Data were statistically analyzed, and were mapped in 2-D and 3-D using ARC/INFO and Dynamic Graphics, Inc., EarthVision programs on SUN and IRIS computers. Files included on this publication can be retrieved for use in other applications, including graphics editing and display, and statistical programs. Graphics are stored as GIF (.gif) and JPEG (.jpg) images (see glossary for explanations of some acronyms and words). Respective files are located in the "imagegif" and "imagejpg," subdirectories and can be opened using numerous graphics programs.

World Wide Web (WWW) network-browsing software is required to integrate the graphics images and text located on this publication. While included HTML (Hypertext Markup Language) documents (in the "htmltxt" directory) can be viewed with standard word-processing software, the interactive capabilities of Web browsing software link text, images, and data. Provided graphics are designed for use under DOS/Windows on IBM or 100 percent compatible personal computers (PC's), the Apple Macintosh family, and UNIX computers.

Brand and product names are trademarks or registered trademarks of their respective companies. The tm notation is not appended to these product names, largely because the HTML superscript notation did not work with all World Wide Web (WWW) browsers.

The file-naming convention on this report is primarily eight dot three (ISO 9660 convention). This indicates that the file has a maximum of eight characters to the left of and three to the right of the "." . An asterisk (*) is used in this publication as a symbol to match all characters. It commonly indicates a longer file name, for example Introd*.hqx would access all .hqx files that start with "Introd" and end with .hqx, such as Introduction.hqx. UNIX is case-sensitive, almost all file names within directories (folders) are lower case.
