Franklin Electronic Publishers Inc., an electronic publisher of books and other information, said today it has stepped up its search for acquisitions in order to fuel growth and expand its business.

The Burlington company said it expanded its investment banking relationship with North Haven Partners Inc., of New York, which provides merger and acquisition advisory services. Financial terms were not disclosed.

Franklin said it established an investment banking relationship with North Haven in July 2006 and previously was focused on linguistic technology acquisitions for its Proximity Technology Division.

"Now that we've turned the corner, have cash on hand and access to additional financing, we're well equipped to be seeking accretive acquisitions to help fuel our long term growth," said Toshihide Hokari, Franklin's Vice President and Chief Corporate Development Officer.

The New Jersey company has more 40,000 electronic book titles, either available directly or through partners, in 16 languages. Most are books that can be read on a Franklin device, a Windows desk top, and on standard operating systems such as Palm and Blackberry.

Shares rose 11 cents, or 3.67 percent, to $3.11 on the American Stock Exchange.
