Last year, around this time, I had a post on the number of cites to the Volokh Conspiracy in the Westlaw JLR database:

Volokh Conspiracy Citations in the Westlaw JLR Database:
By year: 2004, 14 citations. 2005, 22 citations. 2006, 69 citations. 2007, 43 citations. Note that the high number of citations in 2006 resulted in part from the publication of papers from conferences about law blogs, and that the number of citations for 2007 will likely increase in the future because not all journals have posted their final 2007 issues to the database. (Methodology: JLR database queries for "volokh conspiracy" limited to each year.)

Here's another year to add, based on running that same search today: 2008, 78 citations. Also, the total for 2007 ended up at 55, about 20% more than the 43 in the database in late January, so the 78 is likely to grow to near 100 when all the issues are done. (Obviously none of this is earth shattering — just kinda interesting for us legal academics.)
