Expert witnesses are a part of the discovery portion of the case. Experts are hired when facts are in dispute: did the doctor follow the standard of care in that situation? Did the company use the correct pipes in their products for that purpose?
Sometimes experts are used to consult on a case (called consulting experts), and some experts are used to testify (called, you guessed it, testifying experts). Testifying experts introduce evidence in the form of testimony (either during depositions or trial), and via affidavits and reports.
This guide only discusses testifying experts.

One important case you'll often see when expert witnesses are mentioned is Daubert.
The links below will take to you some general toolkits and resources pertaining to expert witnesses. They're geared towards practitioners, not students, which is great because they're 1) meant to be practical 2) meant to be read by busy people.

So, you know you need an expert witness, maybe even multiple ones. How do you find one beyond random Google searches? Westlaw has the edge over Lexis in this situation. While Lexis has databases where you can search expert CVs, finding them depends on 1) what they write in their CVs and 2) your skill in crafting Boolean searches to find appropriate experts.
Also! Another checklist: Westlaw's Locating an Expert Checklist.
Westlaw's Expert Materials Databases
To identify experts, you have two options on Westlaw (Lexis is listed below): Expert Directories and Expert Profiles. Check out Profiles FIRST. You can expand the area of expertise to locate witnesses who have experience, for example, in boating accidents and accounting damages to help determine what's an appropriate amount of damages to claim in your client's boating accident case.
NB - DO YOUR DUE DILIGENCE!
If you find a potential expert witness via Google (or Westlaw, or whever), your job is NOT done!! OR, once opposing counsel has disclosed their experts to you, YOU HAVE WORK TO DO!

Daubert challenges (aka Daubert motions) seek to exclude presenting evidence by one expert (testimony or report) to the jury. Named after the 1993 Supreme Court case, Daubert v. Merrell Dow Pharm., Inc., you can't effectively use experts without having some knowledge of how this case will affect your expert's admissibility.
