Abstract To make fiscally and academically responsible selection and deselection of subscribed content, it is critically important to have reasonably accessible usage data for those resources. To this end, the organizers of Project Counting Online Usage of NeTworked Electronic Resources (COUNTER) initiated the development of a standard known as the COUNTER Code of Practice. Beginning with the year 2019, COUNTER 5 standardized usage reports are available for most commercially published electronic information resources such as online journals, aggregated research databases, and ebooks. This column explores some of the differences between the COUNTER 5 Title Master Report-Journal Report (TR-JR1) report and the COUNTER 4 JR1 report for online journal usage and offers some assistance in extracting specific data from the TR-JR1 report that is not as readily visible as it was in COUNTER 4 reports.

摘要 为了在财政和学术上对订阅内容进行选择和取消选择，为这些资源提供合理可访问的使用数据至关重要。为此，网络电子资源在线使用项目计数 (COUNTER) 的组织者发起了一项称为 COUNTER 实践准则的标准的开发。从 2019 年开始，COUNTER 5 标准化使用报告可用于大多数商业出版的电子信息资源，例如在线期刊、聚合研究数据库和电子书。
