With a title like this I should attract a lot of hits -;) But to call me a Black Hat spammer right away, I don't think so. I believe this reseach deserves a lot of attention.
I wonder if Jeroen Bosman will publish his report "Scopus doorgelicht en vergeleken : de dekking van de citatiedatabase Scopus inclusief vergelijkingen met Web of Science and Google Scholar" on this subject also in English. (He just confirmed to me he will, so be patient!)
In the ongoing debate about the language of blogging/publication, I am convinced that in this case the language of publication is a negative impuls.
Making it available in a open repository is on the other hand a very positive point. There is certainly international interest for this!
In a free translation it would be: "Scopus examined and compared: the coverage of citationdatabase Scopus with Web of Science and Google Scholar."
There is also a powerpoint available. This presentation is also in Dutch, but will give you a very nice extra insight and overviews of coverage with example searches and hits.
This sure is interesting reading and an English summary would be great. You will have to wait for that i am afraid and be satisfied with a short preliminary one based on highlights of the summary.
Highlights of the summary:
- Changing student search habits (less focus on speciality databases, using links rather than searching systematically) and the appearance of "competitors" like Google Scholar and perhaps Windows Live Academic make research into multidisciplinary databases necessary
- Content: Scopus has almost 28 million record and WoS -including backfiles- 37 million. Scopus includes 15.000 journal titles against almost 9000 in WoS.
- Coverage: •preliminary conclusions: –Scopus has after 1996 about 30% more, and béfore that about 10% less coverage than WoS –Scopus coverage has a whimsical, hard to explain course through time –Coverage in bio/earth/geog/enviro/engin/comp very good –Coverage health also very good, but doubt over most recent years –Coverage psych/antropo/econ/chem acceptable, but before 1996 there are several gaps –Coverage phys/astro/math/socio less good, or reasons for doubt –Hardly coverage philo/theo/arts/lang
- Up-to-dateness: there is hardly any difference between WoS-Scopus considering the speed of updating records
- Citation details: again the difference is rather small, there is a large overlap between WoS-Scopus, but the difference with Google Scholar is larger and it finds more ánd more unique publications.
- Speed: Google Scholar is faster than WoS or Scopus. WoS has the disadvantage of being a little slower than Scopus.
- Opinions: most "power users" like the Scopus interface and value the Refine and Citation Tracker, but it can not replace -for the time being- the Journal Citation Reports, according to them.

I'm not sure in what stage that articke is at this moment. I know Jeroen is reading your blog, so perhaps, this is an open invitation for a comments from his side.
And together with the powerpoint this is very understandable, even for non-Dutch speaking readers.
