The Business Center at SNFL is the successor to the former Science, Industry, and Business Library (SIBL), which was located at 188 Madison Ave. SIBL's Bloomberg terminals have been moved to SNFL. The SNFL branch is an ~7 minute walk from the former SIBL facility: from the former SIBL entrance, head north on Madison Ave and turn left (west) when you reach E39th St. Turn right on 5th, heading north until you reach the SNFL entrance at 455 5th Ave.
Some major metropolitan library systems, especially those with a business branch or department, may subscribe to Bloomberg. Contact your local public library to ask if they have a terminal. (Most small community public libraries cannot afford Bloomberg. It is extremely expensive.)
