Article Processing Charges (APCs) are fees charged by publishers to make articles in scholarly journals open access, specifically to cover the costs of publication and journal administration. However, many scholarly journals, particularly those supported by universities, publish open access with no costs at all to researchers.

HKU is a member of Bentham OPEN, which allows a 50% discount for HKU corresponding authors, and any HKU co-author. To receive this 50% discount, authors must include this code in cover letters, when submitting manuscripts: BOMI-HKU/01.
HKU has a Supporter Membership with BioMed Central. If the affiliation of the submitting author (author who uses the BMC online submission system) is HKU, then there will be a 15% discount. Therefore if you are one of the co-authors on a paper, please check with your other co-authors to determine which of their affiliations if any, have Supporter or Prepaid Memberships with BMC. Then the co-author of the affiliation with the most BMC discount could submit the article through BMC's online submission system. BMC writes,
When submitting a manuscript, either via a journal home page or via our online submission system, you will be identified as belonging to a member institution and automatically granted an article processing charge waiver if you are within your institution's firewall. If you are at home or at an external terminal when submitting your paper, you can still claim a waiver by starting your affiliation to your institution.
Multidisciplinary Digital Publishing Institute (MDPI) 
HKU Libraries is a member of the MDPI´s Institutional Open Access Program (IOAP). Under the IOAP scheme, HKU author can receive a 10% discount on the Article Processing Charges (APCs) for any papers published in an MDPI journal. Note that only one discount through an IOAP scheme is permitted per paper, and the discount cannot be combined with other available discounts, such as discount vouchers, and society membership discounts.
As a subscriber of Policy Press, HKU authors can enjoy a 20% APC discount on all Policy Press journals. Please quote the customer number (CU-0128046) when making enquiries about open access with Policy Press.
Proceedings of the National Academy of Sciences of the United States of America (PNAS) 
Because HKU Libraries have a paid subscription to this journal, the publishers will allow a discount on article processing charges (APC). After the discount, the APC is $4,975 for Immediate Open Access. However, there is no discount for Delayed Open Access. Please make sure the corresponding author lists “University of Hong Kong” as the affiliation. Then, the system of PNAS can match it to HKU subscriber record and add the discount. The corresponding author should receive an estimate of publication charges. You are also encouraged to check for the discount so that PNAS can make any corrections if needed.
Because of the HKU Supporter Membership of BioMed Central (above), HKU authors (submitting author) may also claim a 15% discount in SpringerOpen journals. Submission process is the same as in BMC above.
Directory of Open Access Journals 
There are many more OA journals, many with no OA charges. The Directory of Open Access Journals lists 10,000+ journal titles, searchable by title, ISSN, and subject area.
Transformative Agreement (TA)
A Transformative Agreement (TA), sometimes used interchangeably with Read & Publish agreement (R&P), is an agreement with a publisher that takes the library’s existing expenditure on subscriptions and repurposes it to cover both reading and publishing in that publisher’s journals. If an academic publishes in a journal that is included in one of the R&P agreements, they may be able to publish direct to open access with no transactional article processing charges.
The Libraries has signed transformative agreements with the various publishers, providing HKU authors with full Article Processing Charge waivers for publishing articles in eligible open access and hybrid journals. Further details of the agreement terms are listed in the below section.
