It sounds like you're referring to the previous sale information that Trulia displays for listings. This information is still shown on our listing detail pages if it's made publicly available.
I've noticed a few questions similar to this one since we've redesigned our search results page. On that page you can still view information for homes sold within the last nine months if you select Recently Sold Homes under our Listing Type filter on the left side of the page. However we no longer provide the option to browse property records for a particular location. That information is still available but only if you search using a particular property address.
I hope this clears things up. Please let us know if you have further questions.
