The OpenAPC initiative collects and disseminates datasets on fees paid for open access publishing under an open database license. OpenAPC is operated by Bielefeld University Library. The aims of OpenAPC are transparency and reproducibility of OA costs, as well as to illustrate the development of costs over time. The initiative aggregates data on Open Access journal articles (APCs), Open Access Books (BPCs) and data on articles published under transformative agreements.So far, only the actual OA fees have been collected and processed, i.e. APCs and BPCs, including taxes and discounts. Additional costs that are also linked to electronic publishing, such as colour or page charges, were not included. Within the framework of the openCost project the OpenAPC infrastructure was extended so that these additional costs can also be aggregated. Collecting and analysing these types of costs is intended to show how relevant they are in relation to classical APCs and what share the various cost items make up in the overall picture.By using the openCost format, OpenAPC is able to standardise its harvesting process and offer institutions the possibility to report additional costs. The talk presents the implementation and processing workflows, including some initial data and analysis options, as well as potentials and ways of providing your additional cost data to OpenAPC.
