The fourth edition of SEG's bestseller is now available in its entirety on the wiki - for free. This is a valuable, comprehensive reference that is a must for every geophysicist, geologist, explorationist, engineer, energy adviser, economist, and student involved in the field. In the printed form of the book, a CD containing the dictionary in searchable PDF format also is included.

Common editing tasks

Since Robert Sheriff conceptualized a written book when completing his work, there are three common issues that detract from the full online experience. These issues arise:

  1. the equations
  2. the references
  3. the figures

Equations

Most of the equations in the Dictionary are poorly formatted. This is due to the initial conversion process from book to wiki.

If you know LaTeX, or are willing to learn, you can help us fix them. The site that will help you fix these equations is CodeCogs. CodeCogs is a visual website that allows you to create the math code you need.

This article provides numerous examples of the proper math code. Visit this page for a list of articles that need fixed.

References

Just like technical papers, wikis need citations and references if they are to be useful and trusted. Frequently, references will appear in the articles without the proper citations. This is the full list of references that appear in the Dictionary. Use this page to locate the missing full citations in the Dictionary articles.

The Q article has been fixed. Here are two that need to be fixed: anisotropy and tomography.

Note: References are more difficult to find since there is not a category listing all of the pages that need references. Many of the articles, including Dictionary figures, will need to have references added.

Figures

As with references, most of the figures do not appear in their entirely on the article. All of the figures for Sheriff’s Dictionary have captions. We will retain the captions when adding the figures to the Dictionary entries.

It is possible that these figures will have the same issues as the dictionary entries: improper math and no references. I encourage you to address these issues in the figures as you see them.

The Q article shows one way to integrate them. Some articles have lots of figures. The tomography article needs fixed..

Sheriff's Dictionary contest

The first user that fixes the s-wave article - incorporating the math equations correctly and integrates the figures and references within the article - will receive a 2014 SEG Denver coffee mug.
