The US ISSN centre breaks a record

The U.S. ISSN Center assigned a recordbreaking 6,341 International Standard Serial Numbers (ISSN) in 2019, an increase of 10.5 percent over fiscal 2018. Of these, 2,621 ISSN, or 41 percent, were assigned to online resources. ISSN statistics over many years show that print resources continue to be published at a steady rate. The high number of ISSN assigned to publications requested by CONSER libraries in 2019 represented the successful elimination of an arrearage of more than 1,500 titles that had accumulated, partly as a result of libraries requesting ISSN for older print titles being digitized or moved to off-site storage. In 2020, the U.S. ISSN Center plans a project for more than 5,000 titles in HathiTrust and a project to assign ISSN to science blogs. Work continues on ISSN Uplink, an ISSN web form application, workflow, and communication system.
