Personal Injury Lawyers as well as any other attorney, pay to be listed in directories all over the net. BEWARE! Don't make your decision based on how good their ad looks or how many times you've seen their names plastered everywhere you look.
Make sure that before you make your decision on who you're going to hire you read their feedback. There are countless websites giving client feedback on lawyers across the country. Don't make decisions that are not purely based on knowledge and experience.
Citysearch and Yelp are good examples of local feedback websites where you can learn from the experiences of others. A lawsuit is not a cakewalk and your decision for a good lawyer will make the difference in the end.
