## Known gaps

- CourtListener's court record shows no automatic collection of new opinions from Massachusetts District Court. Check the court's own website for recent ones.
- Only part of Massachusetts Supreme Judicial Court's website could be read in our check, so its years and text search are not fully measured.
- We found no search of opinion text on Massachusetts Supreme Judicial Court's website, only lists or lookup by name, number or date.
- The Caselaw Access Project holds published opinions only through 2017.
- Our survey lists no free statewide source of trial-court opinions for this state.
