The biblioblogosphere is comprised of the institutional publication of blogs of libraries and the personal, professionally-oriented publication of blogs by librarians. Since introduction of this neologism in 2004, a number of researchers have examined this particular class of bloggers and blogging. However, there is limited investigation into the structure and connectivity of blogs within the biblioblogosphere. This article reports a study of interlinkage patterns within a sample of 1,604 biblioblogs. Findings suggest the biblioblogosphere conforms to the locally dense, globally sparse structure of blog networks established by previous studies of other blog types. The majority of blogs within the sample did not link to any other sampled blog. Those that did tended to cluster according to library type, blog subject, or geographical proximity. About one-third of the interlinked blogs were located within a single, massive component (that is, a networked group of blogs), while the rest were in smaller networks of two or three nodes. Personal biblioblogs, characterized as blogs published by individuals independently of an institution, are more likely to be located within a more densely populated network than institutional blogs. These findings indicate that “personal-professional” bibliobloggers are actively shaping the structure of the library blogosphere, while institutional blogs demonstrate much less overall connectivity. 相似文献

New indicators for gender studies in Web networks 总被引：2，自引：1，他引：2
New indicators for gender studies are introduced using the multi-authored publications of a set of 64 members of the COLLNET network. Considering the sample of 223 papers and their visibility on the Web, analyses were performed on the sets comprised of publications on the one hand and the authors (social network analysis) on the other.The indicators developed include: Gender co-operation; Web visibility rates and Gender centrality in networks.The co-operation among COLLNET members results in a publication set with a different pattern to other gender studies in science, which show low contribution rates of women in collaboration activities. In the sample the collaboration patterns of female COLLNET members are almost the same as their male counterparts. However, when considering only the arrangement of gender in the by-line of publications, this is in favour of men.Regarding average Web visibility rates, there are no differences dependent upon the arrangement of gender in publications with both male and female co-authors. However, the results also show strong gender differences in favour of publications with only male co-authors.The centrality of female actors in the networks is correlated with the central positions of women in the International Society for Scientometrics and Informetrics (ISSI), where they are leading either as presidents or organisers of its international conferences.It may well be that, with webometric methods and new indicators for gender studies, there is a real continuation of gender equality in COLLNET over time. 相似文献
