Three publishing giants-Thomson/West, Reed Elsevier and Wolters Kluwer- have cornered the market of what used to be a wide number of legal research and reference publishers.

Where are LexisNexis and West Group in the mix? Take a look. Another commentator has compiled a pie chart showing how the publishers are represented in terms of market share.
