For Expert Witnesses and Consultants, there is great value in writing articles and books. For many, books, peer-review articles and papers are a natural progression in the acquisition of knowledge. It may be something new for others who have already acquired a great deal of information on a certain subject. In any case, publications are solid evidence of an Expert’s knowledge in his field of expertise. As such, including a list of publications on an Expert’s Curriculum Vitae is an excellent way to increase credibility. 
In addition to credibility, publications help to garner attention. Many attorneys rely on the Internet to find articles or papers on subjects specific to their cases. If an Expert’s name is attached to the article, it follows that the attorney has found her Expert Witness for the case. For example, if an attorney is doing a Google search on mold and he uses the search terms “mold exposure experts”, Expert Witness, Dr. Joseph H. Guth’s, article, “Mold Exposures Need Better Medical Responses,” appears No. 1 out of 4,540,000 results (link from Experts.com)*. In a search using the phrase “motor vehicle experts,” Experts.com member, Dr. Irving Ojalvo’s, article, “Optimizing Your Use of Motor Vehicle Experts,” is No. 1 out of 6,230,000 results.
Although one may hold himself out as an Expert Witness or Consultant, the depth of his knowledge is not always apparent. Case scenarios and case studies are an excellent way for those looking for higher knowledge to apply a specialty to specific factual situations. These case scenarios can be linked to an Expert’s or Consultant’s website or made readily available to anyone looking to retain him for his services.
Caveat: All writings are discoverable and can be used in depositions and in court. If an Expert understands his area of expertise, then there should be no problem with this, however, remember to be consistent and factually correct.
