It depends on the specific policies and guidelines of Scopus regarding the journal and its indexing process. Generally speaking, if a journal is accepted for Scopus indexing, papers published in that journal after the acceptance date should be indexed in Scopus. However, it is important to confirm with the journal directly and to review the specific requirements for the acceptance and indexing process to ensure that your paper will be included in the Scopus database. It is recommended to review the Scopus website and the journal's website to learn more about their respective policies and procedures.
I suppose that you mean that again a number of new titles are accepted in March 2023 (see enclosed file). In general, it means that at some point the journal title will be added to the Scopus source title list (as will be visible here https://www.scopus.com/sources.uri?zone=TopNavBar&origin=searchbasic ).
However, in the text (disclaimer) above the list of “Accepted titles” it states: "Notice: Scopus is owned by Elsevier B.V. and Elsevier is solely responsible for the content selection policy of Scopus. In order to come to a decision to accept or reject a title for Scopus, Elsevier follows the independent advice from the Scopus Content Selection & Advisory Board (CSAB). However, Elsevier and the CSAB reserve the right to change decisions, adjust the selection criteria, or re-evaluate titles that are accepted for Scopus without prior notice. Decisions made by the CSAB do not guarantee inclusion into Scopus due to not being able to come to terms with the publisher on a licensing agreement. In no event shall Elsevier be liable for any indirect, incidental, special, consequential or punitive damages arising out of or in connection with any advice disclosed or any selection decision made. This statement must not be used for advertisement purposes.”
In other words, things like financial disputes, improper metadata etc. could be reasons that some titles will not end up in the indexed list (or take an extreme long time). See for an example here on RG this question:
In general publishers like Springer, Elsevier, MDPI and Frontiers journals manage to get their journals included pretty fast (based on their experience, reputation, their knowledge about how to provide all necessary info etc.). Smaller publishers or stand-alone journals need more time.
So, it depends. If you want to be absolutely sure (and need a publication in a Scopus indexed journal) you better choose a journal that is already indexed in Scopus (for a number of years).
I agree with the final point made by Rob Keller that if you want to be absolutely sure, then you may need to select one that is Scopus indexed already and not take the risk that the journal might be officially included in the future That may take some time.
Scopus indexing, as I understand, is important to many individuals. Is this requirement a personal choice or set by your organisation?
If a journal has been accepted for Scopus indexing in March 2023, it means that the journal will be included in the Scopus database starting from that date. However, it does not necessarily mean that all the articles published in the journal will be immediately indexed in Scopus. The indexing process usually takes some time, and it depends on various factors, such as the quality of the article, the relevance of the topic, and the compliance with Scopus guidelines.
If you submit your paper to a journal that has been accepted for Scopus indexing but has not yet been indexed, it is important to check with the journal about the status of the indexing process and the expected timeline. You can also check the Scopus website periodically to see if the journal has been indexed and whether your paper has been included.
Rajan SALUJA Saluja I think that it is Ok, the article will appear in the Scopus website. Also, all the answers seem to be very good and are useful to most of researchers. However, the important question that I would like to share with the respectful professors and colleagues is that will this journal (which is not yet in the Scopus List, but accepted to be processed) in this status be considered indexed in Scopus by organizations or Promotion Committees?
Dear Rabea A Gadelkareem I think that strictly speaking a journal will not be considered Scopus indexed until it finalised all steps and is listed in the Scopus Sources title list as can be found in the source list (see for latest list enclosed file). This because of the reasons I indicated in my reply of April 24th, with basically the message not all accepted titles make it to index in the end.
Rajan SALUJA Saluja can I congratulate you with your paper that is published in "Journal of Autonomous Intelligence" which is now officially indexed in Scopus (with CiteScore of 1.1.) https://www.scopus.com/sourceid/21101111528
as one can see, this is an example where the accepted title reach full indexing and even stronger the coverage is not 'just' 2023 but all papers published since 2019 are covered as well (and considered as Scopus indexed).
Dear Rob Keller, This is exactly what I have asked for that the journal will not be considered Scopus-indexed, unless it is included in the Scopus title list (finalized all the steps), as you have confirmed.
For example, if I submitted my files for a promotion, where the promotion committee considers at least the Scopus-indexed journals at the time of publication of the articles. Then, the article in a journal which is accepted but have not been indexed in Scopus yet, the committee will consider the article as one published in a non-indexed journal.
Dear Ahmad Amin Khalil Indeed, according to their own website (https://ejournal.undip.ac.id/index.php/lawreform/index ) they were accepted in Scopus in March 2023. In the Scopus Source list, they have been included in the Tab “Accepted titles”. Update: They are now fully indexed https://www.scopus.com/sourceid/21101146387 As far as I can see they were included in the Tab "Scopus Sources" in November 2023 (see enclosed file). This is pretty fast, some titles have to wait long (if not forever) before the title is moved to the ‘official’ index list, but further details and full inclusion of the papers from 2019 to present will take a while.
So, I think that in the coming months the details will be included in the Scopus link you provided.
