From the blurb for National Survey of State Laws, 8th edition, edited by Richard Leiter:
The National Survey of State Laws (NSSL) is a print and online resource that provides an overall view of some of the most-asked about and controversial legal topics in the United States. This database is derived from Richard Leiter’s National Survey of State Laws print editions. Presented in chart format, NSSL allows users to make basic state-by-state comparisons of current state laws. The database is updated regularly as new laws are passed or updated.
The current 8th edition, along with the 7th, 6th and 5th editions, are included in database format, which allows users to compare the same laws as they existed in 2005, 2008, 2015 and 2018, and to make more current comparisons with laws added or updated in the database since 2018. All print editions are included in HeinOnline’ s image-based, fully searchable, user-friendly platform.
