Start of question 1 1 2 3 4 Tefko Saracevic

Explanation For selection of E2 AU= Saracevi. T note the period after the eigth letter You cannot find it in any explanation, but after checking I found that it is a legacy carryover: when Citation Indexes started at ISI they limited author names to eight letters; for longer ones they added a period to indicate that there is more. This was done because originally the input was on 80 column punched cards and a lot of stuff had to be squeezed in 80 columns I checked and all six articles there are indeed by me for papers written between 1972-1974. So papers published before 1974 have abbreviated authors’ names if they are longer than eight letter vagaries of databases …. Tefko Saracevic

Question 2 – but continuing the same search 8 9 10 Tefko Saracevic

Explanation for multiple selections of expand As you noted I selected E3, 9, 11, and 12 Reason – references tend to be messy: name Saracevic was spelled in different ways when included in references under E3 there were 13 articles citing Saracevic (no initial) – I checked, indeed they are all to the right Saracevic, so I included them Tefko Saracevic

Question 3 some explanations A lot of authors make mistakes and wrongly cite given articles (not only author names) - practice is widespread thus I selected all citations, correctly and wrongly cited, for the three articles - e8 to e18 – I examined the selection later & oooops I also made a mistake Citation databases cannot and do not make corrections – they take citations as found in articles Here is an example of a wrongly cited article: Tefko Saracevic

Example for an author Tefko Saracevic

Caveats Results from Google Scholar are inflated coverage not clear what papers included could be even class bibliographies sometimes ghost citations counted a paper did NOT include a citation but counted as if it did e.g. I did not publish 309 papers (although I wish…) I do not have 4166 citations (although I wish …) Different ways an author name is entered produce different results e.g. for Tefko Saracevic & T Saracevic gets different results Tefko Saracevic
