Beginning 09/30/2019, Web of Science has started to index Online First articles published in Springer and Palgrave journals. This new policy is applicable for online First articles published from 10/01/2019. If an article has been published as an Online First article prior to 09/30/2019 and not yet been assigned to a volume and issue of the journal then it will not generally have been indexed by indexing services such as Web of Science (WoS).
The Online First article published before 09/30/2019 will be indexed once it is assigned to an issue and has a complete bibliographic citation including the volume, issue and page numbers.
If the article is not an Online First article and yet is not indexed on Web of Science, please contact us with the details and we will liaise with them to resolve the matter.
