Please note that it may take several months following publication of a new LNCS volume until papers show up on the websites or portals of the services mentioned above.
Depending on the focus of the particular indexing services, they may decide to only include selected volumes of the LNCS series.
Not being a journal, but a book series publishing primarily proceedings, LNCS is not included in ISI's Science Citation Index Expanded (SCI-E) and hence does not have an impact factor. However, references to ISI-listed journals that are cited in LNCS papers do contribute to the respective journal’s impact factor.
LNCS full-text versions are available from our digital library SpringerLink.
