- -Case law coverage is narrower than Westlaw and LexisNexis, with reviewers noting it works less well for older and more historical decisions.
- -Its library of secondary sources and treatises is thinner than the premium platforms, so many practitioners still need Westlaw or Lexis for analytical and how-to materials.
