In Scopus you have a separate bar for Author search. You could also choose to limit to Author in Basic search or search operators in Advanced search. When searching rantapaa s or Rantapää s with Swedish/Finnish diacritic characters ä, you receive 23 hits including the article indexed with the full first name Solbritt.

But if you choose to search with Rantapaa-Dahlqvist S or Rantapaa Dahlqvist you loose the hit with first name Solbritt because that record is spelled Dahlquist.

But searching Rantapaa Dahlquist S doesn’t find all dalhquist-spelled records. Neither does a search for Rantapaa Dahlquist SB or with dots S.B. or with space S B.

When you instead search Dahlquist s, you will find the dahlquist-spelled records.

So when I click on the 20 hits from my initial search Rantapaa Dahlqvist S I get 69 (!) records instead of 20. How come?
Even stranger: When clicking the author name in one of the records, 71 records are retrieved. But the number of records retrieved in the initial search was 72. Could it be more confusing? View this video [AVI]

Still none of the 72 records mentioned includes the article by Rantapää Dahlqvist S she published in Lancet 1998. Searching that article by title shows that her name is implemented as Dahlqvist SR. Clicking on her name under author(s) gives 28 hits. 4 of them give hits on other spelling variants of her name but not all 72 articles from the initial search.

If you check this article “New concept in echocardiography” in PubMed you will see it’s implemented with Rantapaa Dahlqvist S. Checking the article in the electronic source of Lancet via Science Direct (Yes, it’s owned by Elsevier who owns Scopus!) shows the name implemented as Rantapaa Dahlqvist, Solbritt.

So how to find all articles by Rantapaa Dahlqvist S and author variants? The initial search Rantapaa S gives 72 records. Searching Dahlquist S gives 2 records. Searching Dahlqvist SR gives 24 records. Together 98.
Conclusion: Though this author search is an extreme example, it shows the problem of the implementations of author names. You have to search all possible misspellings of a name. Preferably, you should have a proper publication list from the author. And at last WHY is the reference from Lancet discussed above consistent in one Elsevier product (Science Direct) and not in the other (Scopus)?
