On Course, created in 1948 and originally named The Bull Sheet, is the official publication of the Midwest Association of Golf Course Superintendents (MAGCS).

MAGCS was founded in 1926 by a small group of Chicago area "Greenkeepers" and has progressed over time to include a membership of 800 individuals, representing close to 300 golf courses in the greater Chicago metropolitan area.

MAGCS exists to provide networking, education, and career advancement opportunities to those who facilitate the growth and enjoyment of golf. They represent the golf course management profession (both locally and nationally), meet the developmental needs of the membership through education, research, and other technologies, recognize and promote key golf course management positions, and are the main resource for employment opportunities in the Midwest area.

The organization’s award winning monthly magazine, On Course, is mailed to over 950 paid and controlled subscribers and features current golf course management topics and association activities. On Course is dedicated to disseminating scientific and practical knowledge pertaining to golf turf maintenance, documenting the activities of the association, and enhancing the professional stature of the association’s members.

Furthermore, the magazine features articles penned by golf course superintendents for superintendents. Readers receive the latest information about integrated pest and plant management, problem solving techniques, safety regulations, equipment maintenance, new products, innovative practices, employee relations, and environmental stewardship projects.

On Course also features a section on equipment for the growing equipment technician class, not to mention contributions by many other industry professionals. Each issue provides the reader the opportunity to learn about MAGCS, current events, individual members, and the golf course profession.

This archive, an ongoing cooperative project of MAGCS and the Michigan State University Libraries, features On Course / The Bull Sheet content from 1948 to the present. The current and prior calendar year publications are publicly-accessible; however, all previous years are available to only MAGCS members and TGIF users.
