Rising college costs are causing some southwestern Connecticut residents to look for additional financial aid on the state level. Stephanie Rosoff, 19, walked the halls of the state capitol with a purpose Wednesday. She is one of many students urging legislators to support a bill that would require publishers to notify professors of the cost of each textbook they're requiring students to buy. State Representatives Denise Merrill (D-Mansfield) and Roberta Willis (D-Lakeville) are also going to propose additional funding for state financial aid to fill in recent cuts at the federal level. The textbook bill was voted out of committee and is expected to hit the house floor. Students say it would also help increase the availability of the cheaper, used books.
