CLJC is a free service that lets you set up RSS and/or email alerts to current tables of contents from over a thousand law journals, including Harvard Law Review and at least 14 other HLS publications.
CLJC also allows you to keyword search or browse recent tables of contents of the journals. Search results include links to the full article in Lexis or Westlaw (password required), but also free journal websites, and many other sources. If you’re a current Harvard student or faculty member, you can make full-text linking even easier: if you use the Firefox browser you can load the Libx plug-in to help you quickly link to the full text. Once you have added the plug-in, the “Find It” button will display next to each citation, and you can use that to locate any full-text options (other than Lexis and Westlaw) at Harvard (ID and PIN required when off campus).
HLS reference librarians at the 4th floor Reference Desk can help you with setting up alerts or using the LibX plug-in.
