Fortunately and unfortunately, there is no general rule for what is allowed and there are no attorneys (as of 2024) on staff in the library. The library staff cannot give out legal advice. While the library staff should not tell you what is acceptable to scan or copy under copyright law, please see copyright notices posted near the copy-printers and be aware of TCC's copyright policy.
Students and library users must follow copyright law, but if your use of the copy/copies is for educational or research purposes, this typically weighs in favor of Fair Use. For more context, only a court can decide what is or is not a Fair Use. Learn more about Fair Use in this FAQ.
