The law journal feeds project at Washington and Lee now has a working tables-of-contents feature. You can specify how many days ago to start and the server will return a web page containing the information from all the contents pages that were added during that date period.
Something in the order of 100 journals come from feeds operating at publisher sites, and around 400 are from contents pages scanned at the University of Texas Tarlton Law Library (a big thanks to the Tarlton Law Library for this service) which are then reformatted into XML at Washington and Lee. Some of the publisher feeds contain abstracts, which you may choose not to display should you wish.
Suggestions for improvements are welcome.
The law journals feed page is at http://law.wlu.edu/library/feeds/
Should you wish to go directly to the list of feeds, that's at http://law.wlu.edu/library/feeds/listfeeds.asp
And the URL to display contents pages is http://law.wlu.edu/library/feeds/showfeeds.asp?age=3
(where '3' is the number of days ago that you'd like to display from) - also you may add "&noabstracts=yes" to that URL if you wish to suppress the display of any abstracts.
