Updated: The funding has been announced...the round was led by Boulder Ventures, who joins existing investors, Colorado Fund I and Brad Feld. Lijit’s search service allows readers to search blog publishers’ posts, bookmarks, blogroll, and more from a widget placed on the publisher’s property.

Blogging search tool provider Lijit expects to close a $3.3 million second round funding by the end of this month, Alarm Clock reports. A spokeswoman for the company confirmed there is a forthcoming round, but declined to offer details.

In January, the Louisville, CO-based company secured $900,000 in first round funding from an investment syndicate including Colorado Fund I, managed by High Country Venture; Brad Feld, Managing Director of Foundry Group; Seth Goldstein, co-founder of AttentionTrust.org, Majestic Research and ROOT Markets; and Paul Berberian, former CEO of Raindance Communications. The syndicate was rounded out by investments from Lijit’s management team and other Colorado- and nationally-based angel investors. That same month, Lijit began its partnership with FeedBurner’s blog network.
