2015 (Jan-June) UK APC data combined
Datasets usually provide raw data for analysis. This raw data often comes in spreadsheet form, but can be any collection of data, on which analysis can be performed.
The spreadsheet contains data on article processing charge (APC) expenditure of 27 UK higher education institutions during the first half of 2015. It also contains a table aggregating the total number of APCs and total expenditure paid to 20 different publishers from these 27 institutions. A chart shows the average APC price paid to these 20 publishers.
