I have blogged recently about my experiences with Google Scholar Citations. (1,2). It has been useful in highlighting what science I have published that people might find interest as well as trends in citation patterns. It has also highlighted some potential issues in the data.
I must admit I was quite surprised to see that the top cited paper was one from Eastman Kodak company where we looked at interactions between Sodium Dodecyl sulfate and gelatin, followed by work I did at the University of Ottawa. This work was in 1994 and 1991 respectively. This work was almost 20 years ago so it does make sense that the aggregation of citations over the years might have reached those levels. However, I would have expected that my work in the areas of NMR prediction, Computer-Assisted Structure Elucidation (CASE) and Indirect Covariance would have garnered a lot more citations, but that work did come about 10 years later. It is good to see that the more recent papers, for example that from 2008 on internet-based tools for communication and collaboration in chemistry, has garnered a following.
Above is shown a list of my papers from as far back as 1990 that appear to not have any citations. There are also a lot of recent papers listed that I KNOW are cited, multiple times, as they have been referred to in some of my own publications. For example, the second one in the list, from 2009, entitled “Computer-assisted methods for molecular structure elucidation: realizing a spectroscopist’s dream” is an Open Access article and according to the journal statistics it is the top read article of all time on the Journal of Cheminformatics as shown here with, as of this writing, 10770 accesses. In fact, if I search the article directly on Google Scholar I find it IS cited 7 times as shown below.
I don’t know why it shows up as cited in Google Scholar but not in Google Scholar Citations. However, the same issue exists for the paper on the Spectral game. See below. Shows no citations on Google Schoalr Citations but shows 7 on Google Scholar.
Notice that in BOTH cases the article is listed as the Journal of Cheminformatics, not as the title of the paper. Maybe THIS is the reason the citations are missed. Maybe the publisher for the Journal of Cheminformatics is not exposed in a manner that has the publications indexed properly? Maybe….
