GARDINER — Tilbury House Publishers said in a news release that it has been sold to book-publishing veterans and Maine natives Jonathan Eaton and Tristram Coburn, founders of Cadent Publishing.

The Gardiner publishing company was sold March 22 by longtime owner Neil Rolde. Eaton and Coburn plan to grow both imprints, according to the release.

“I’m looking forward to working with Jon and Tris,” Jennifer Bunting, Tilbury House’s publisher, said in the release. “We’ll stay in Gardiner for now, with our present staff, and we’ll be concentrating on acquiring new children’s books and regional titles.”

Bunting said the company would also be issuing Tilbury titles as e-books, which Cadent Publishing has been doing.

Tilbury House was founded 40 years ago and had been owned by Rolde since 1982. The company concentrated on regional nonfiction at first, starting with the well-known “So You Think You Know Maine,” and then broadened its list to include children’s books.
