Brazilian Biblioterics and its actors, 1973-2018

Abstract

The co-authorships network of the Brazilian bibliometrics divided into five periods from 1973 to 1980 is analyzed. It was found that in the period from 1973 to 1980 it is composed of 59 authors with 62 ties. These co-authorships practically quadrupled for the second period from 1973 to 1990, reaching 203 co-authorships with 448 ties. The growth in the size of the co-authorships is not as accelerated in the third decade from 1973 to 2000, when 267 co-authorships were reached with 501 ties. These co-authorships grew to 395 nodes with 501 ties in the following decade and in the last decade to 375 nodes with 501 ties. Density is the ratio of observed ties in the network to the maximum number of possible ties. In this network, the proportion is really very low, reaching 9.5% in the period 1973-1980, falling to 2.2% in the following period, 1.4% between 1973-2000 and 0.6% in the period 1973-2010 and to 0.7% in the last period. In certain situations, a network is divided into subgroups in which all its members are directly or indirectly connected. In the period 1973-1980 there were 14 groups acting in the BB, it grew to 31 components in 12 in the period 1973-1990, but almost doubled to 65 groups operating in the period 1973-2000; it grows to 88 different groups in the period 1973-2010, but decreases to 66 in the period 1973-2018.
