Some commercial publishers charge authors fees known as APCs (article publishing charges) to publish open access. The library has contracts with certain publishers that make it possible for U-M-affiliated authors to obtain discounts on APCs. See the list below for publishers for discounts for which you may be eligible. Each publisher has specific requirements in order to obtain the U-M negotiated discount. Please look at the information (linked) for publishers of interest to you for specific information. Email the U-M Library if you have questions about these discounts at lib-oa-pub@umich.edu.
