Japan Institute of Heterocyclic Chemistry, the publisher of the journal Heterocycles (1973-2023) [0] is suing CLOCKSS, after its content was released on June 25, 2024 [1]. All of the content from Heterocycles had ceased being available online, and per their agreement with CLOCKSS Archive in 2011,[2] all of the journal's 106 volumes have been made available under the CC BY-NC-ND 4.0 license.[3]
For how this works, see "How CLOCKSS Works" [4] & "How LOCKSS Works" [5].
Chemistry World also had an earlier article ("A key chemistry journal disappeared from the web. Others are at risk", 2024-04-09 [6]) discussing the journal's sudden disappearance [7] and the loss of access when it went offline, an increasingly common problem with scholarly research.
