ANGEL Learning and Houghton Mifflin Form Alliance to Deliver Learning Content in ANGEL Format

Indianapolis, Ind. — Aug. 15, 2006 — ANGEL® Learning, recognized innovator of enterprise e-learning software and services, today announced an alliance with Houghton Mifflin Company, one of the leading educational publishers in the United States. Under the alliance, learning content published by Houghton Mifflin College Division will be formatted to be compatible with the ANGEL Learning Management Suite. 

"Providing content in the form most convenient for our customers is integral to the Houghton Mifflin commitment to customer service," said Jennifer Bubriski, senior product manager for course management system products, Houghton Mifflin College Division. "Making content available in the ANGEL format is one more way we can add value to our customers' experience."

ANGEL LMS is rapidly gaining popularity across K-12 and higher education. ANGEL's powerful online teaching and learning tools foster broad, deep adoption across entire institutions. Its simplicity allows the technology to blend into the background even as it becomes integral to today's learning experience. Houghton Mifflin will make ANGEL format content available across the range of materials its College Division publishes.

"ANGEL Learning diligently seeks to forge relationships that benefit the quickly growing ANGEL constituency," said Christopher Clapp, ANGEL Learning president and CEO. "Our alliance with Houghton Mifflin benefits ANGEL customers now and will serve their evolving needs."
