2 Finnish Science in International Comparison: A Bibliometric Analysis Publications of the Academy of Finland 15/06 Raportin sisällöstä Raportissa tarkastellaan Suomen kansainvälisen, tieteellisen julkaisutoiminnan rakennetta ja tasoa sektoreittain, organisaatioittain ja päätieteenaloittain 1990-luvun puolivälistä lähtien. Lisäksi raportissa vertaillaan kansainvälisesti suomalaisen tutkimuksen tuloksellisuutta ja tasoa sekä näkyvyyttä ja tieteellistä vaikuttavuutta 20 vuoden ajalla 1985–2005.

4 Finnish Science in International Comparison: A Bibliometric Analysis Publications of the Academy of Finland 15/06 Bibliometriset tiedeindikaattorit Bibliometristen tiedeindikaattoreiden käyttökelpoisuus rajallista ja tulkitseminen harvoin ongelmatonta Voidaan hyödyntää arviointien apuna, keskustelun herättäjinä ja erilaisten kysymysten asettelussa. Julkaisu- ja viittauskäytännöt vaihtelevat tieteenaloittain, joten eri aloja ei voi verrata suoraan toisiinsa. Eri aloilla suuriakin eroja mm. reaktionopeudessa uuteen kirjallisuuteen, julkaisujen eliniässä sekä julkaisu- ja viittauskäytännöissä.
