The oldest recs (2004 - 2007) can be found listed in the memories. (http://www.livejournal.com/tools/memories.bml?user=crack_van&keyword=Sherlock%20Holmes%20Fanfic%20Recs&filter=all)

For newer ones, you have to use the tag "sherlock holmes" which will bring up the prior recs. (http://crack-van.livejournal.com/tag/sherlock%20holmes)

Hope that helps.
