Abstract 
In our study we analysed 3.889 records which were indexed in the Library and 
Information Science Abstracts (LISA) database in the research field of 
informetrics. We can show the core journals of the field via a Bradford (power 
law) distribution and corroborate on the basis of the restricted LISA data set 
that it was the appropriate time to found a new specialized journal dedicated to 
informetrics. According to Bradford’s Law of scattering (pure quantitative 
calculation), Egghe’s Journal of Informetrics (JOI) first issue to appear in 2007, 
comes most probable at the right time.

Introduction 
In the new Journal of Informetrics (JOI2) recent call for papers Leo Egghe 
mentioned that Elsevier (Oxford, UK) accepted his proposal for the foundation 
of this new scientific journal. It will be the first journal worldwide which 
carries ‘informetrics’ in the journal title. He explained in an editorial why this is 
necessary (Egghe, 2005). One main reason is the growth of the field 
informetrics. A broad definition of the field informetrics can be found in 
Egghe’s introductory paper in the first special issue on informetrics in 
Information Processing and Management Vol. 41(6): “we will use the term 
“informetrics” as the broad term comprising all-metrics studies related to 
information science, including bibliometrics (bibliographies, libraries, ...), 
scientometrics (science policy, citation analysis, research evaluation, ...), 
webometrics (metrics of the web, the Internet or other social networks such as 
citation or collaboration networks), ...” (Egghe, 2005 p. 1311).

Egghe states several studies to show that the number of papers and authors in 
informetrics are constantly growing. In terms of multidisciplinarity, the field 
informetrics is also expanding, this can be shown by new research topics like 
webometrics and other web based informetric methods (see a review in 
Björneborn & Ingwersen, 2004).  
In the following sections we will show briefly that the distribution of papers 
published in the broad field of informetrics can be used to consider if a new 
forum of scientific communication is necessary. For establishing a new 
scholarly journal publishers generally require, on average, not only hundred 
papers per year from a hundred scientists (Umstätter, 2003), they also need to 
have a few hundred interested readers. 
 
Informetric papers in the LISA database 
To generate a data set of papers in the field of informetrics we used the Library 
and Information Science Abstracts (LISA) database3. The query bibliomet* OR 
cybermet* OR infomet* OR informet* OR scientomet* OR webomet* generated 
a total of 3.889 records that are indexed in LISA (1976-2004, CD-ROM 
version). The records are indexed under the following terms (Table 1): 
 
Query terms Total records

bibliomet* 2851 2414
scientomet* 1631 629
informet* 292 90
webomet* 18 11
infomet* 15  -
cybermet* 7  -
Table 1: Distribution of LISA records in “informetrics” 
 
First we produced a bradfordized list to show the core journals which published 
the most papers in the field (see Figure 1). By using Bradford’s Law of 
scattering (see e.g. Garfield, 1980; White, 1981; Nicolaisen & Hjørland, 2007 
to appear) it is possible to extrapolate the number of publications in the world if 
we know the core journals. In principle, if a new journal arises the number of 
scientific publications, has to be about 2 to 3 times higher than 100, because 
Bradford’s Law of scattering means, that all other journals in the world are also 
attractive for such publications, but with a decrease that follows the power law.

“Webometrics”.

Figure 1: Bradford distribution of papers in “informetrics” (LISA data set) 
 
It is simple to see that the core journal of the field Scientometrics5 is ~2 to 4 
times higher than expected by the Bradford distribution (see Figure 1 and Table 
2). The core journals in our Bradford analysis are the following (compare to the 
journals Egghe mentioned in his editorial (2005)).

5 The journal Scientometrics was founded in 1978 and was swiftly included into E. Garfield’s 
Science Citation Index (SCI). It is published at Akadémiai Kiadó, co-published with Springer 
Science. The Editor-in-Chief was from the outset T. Braun, Hungary. This journal was begun 
very early when ~100 articles per year appeared in our LISA data set.

It seems to be clear that some journals are highly represented due to a special 
indexing of LISA. Beyond that we extracted the most productive authors in the 
informetrics field (see Table 3).

The distribution of languages shows that the field informetrics is highly 
dominated by English. The special indexing and coverage of LISA is again a 
reason for this.

Growth and competition in informetrics 
Starting with „statistical bibliography“, in 1922 we can understand E. Windham 
Hulm as a pioneer. Interesting works from Bradford (1934), Lotka, Otlet, 
Pritchard, Zipf and others followed. If we look to the expansion of this field in 
LISA the growth rate seems to be some 10 years (see Figure 2).

Figure 2: Growth of publications in “informetrics” 
 
A rough estimation of papers in the field of informetrics in LISA shows the 
doubling rate for a 10 years period to be twice the normally seen value of 20 
years. Under the assumption that LISA (dotted line in Figure 2), like similar 
databases, has only ~40% of the whole amount, we can calculate a number of 
~500 published papers in 2002 (straight line in Figure 2).  
 
Calculating the core journals only for the year 2002 (without the comparable 
too high value of Scientometrics), then we can extrapolate it to the total number 
of some 100.000 running journal titles in the world (see Figure 3). In this case 
we get 430 papers in 2002. By a growth rate of 7% per year (t2 = 10 years), we 
have approximately 600 to 700 papers in 2006. But this value is also based on 
LISA, and additionally we know that some of the core journals are not indexed 
adequately.

Another possibility is to calculate Bradford’s Law of scattering using as of all 
the years included in LISA (see Table 4 as an idealized example) to reconstruct 
the publication growth for all journals with a doubling time of 9.6 years.

Then we can estimate roughly the number of 1.000 publications in 2005 in this 
field (see Table 5). The factor 2.5 means, that empirical assessments have 
shown repeatedly, that the search in one database has only a recall ratio of 
roughly 40%. Searchers know the motto, since the seventies of the last century, 
“one database is not enough”.

Table 5: An estimation of papers in “informetrics” (idealized) 
 
This can easily be interpreted as meaning that there is room for a new journal 
parallel to Scientometrics, given the pure quantitative calculation. And it is not 
too early, especially if it is better or more specialized than the competitors.  
It can be noted here that the journal Cybermetrics first appeared in 1997, and 
surprisingly not one of the papers is indexed in our sample from LISA. 
Cybermetrics is an “International Journal of Scientometrics, Informetrics and 
Bibliometrics” dedicated to informetric and webometric studies. It is also an 
irregular appearing open access journal with only a few papers per year. The 
editorial board with 29 well known person, is including also Leo Egghe and 
Ronald Rousseau from Belgium. In 2004 a further journal dedicated to 
webometrics, named Webology, appeared quarterly as an electronic journal 
with two issues in 2004, four issues in 2005 and one in 2006. The editor in 
chief is a PhD candidate from Teheran. It is remarkable that open access 
journals are not automatically more often indexed and highly cited journals. 
Webology is cited only 3 times in Web of Science (WoS) with 2 first authors 
while Cybermetrics was cited 240 times in WoS with 9 first authors with a clear 
decrease since 1997. More than 50% of the citations go back to papers of R. 
Rousseau. 
A comparison of editorial boards is warranted as theses scientists often use their 
journals as a platform for their own publications (see Nourmohammadi & 
Umstätter, 2004) and collaborations6.  
Regardless, new journals are often founded too early. The consequence can be 
observed very easily by the death of roughly 50% of new journals (Umstätter & 
Rehm, 1984). The reason for this is also very simple; scientists on the search 
front always want be the first. 
 
Conclusion 
There has to be improved standards of quality and increasing specialization has 
to be found in the growing area of informetrics. Better measurements of 
information and knowledge would be one of the great desiderata. If we 
remember that in 1963 a first very rough estimation of the amount of 
information in the Library of Congress was calculated with 1013 bit7.  
The new Journal of Informetrics with its focus on “good mathematical 
(probabilistic) models and explanations of informetric regularities (in the broad 
sense) and/or papers in which interesting and important data-gathering” comes 
at the right time, according to our study. The basis of a well known publisher is 
empirically also very important.

Cybermetrics is an “International Journal of Scientometrics, Informetrics and Bibliometrics” dedicated to informetric and webometric studies. It is also an irregular appearing open access journal with only a few papers per year. The editorial board with 29 well known person, is including also Leo Egghe and Ronald Rousseau from Belgium. In 2004 a further journal dedicated to webometrics, named Webology, appeared quarterly as an electronic journal with two issues in 2004, four issues in 2005 and one in 2006. The editor in chief is a PhD candidate from Teheran. It is remarkable that open access journals are not automatically more often indexed and highly cited journals. Webology is cited only 3 times in Web of Science (WoS) with 2 first authors while Cybermetrics was cited 240 times in WoS with 9 first authors with a clear decrease since 1997. More than 50% of the citations go back to papers of R. Rousseau. A comparison of editorial boards is warranted as theses scientists often use their journals as a platform for their own publications (see Nourmohammadi & Umstätter, 2004) and collaborations6.  Regardless, new journals are often founded too early. The consequence can be observed very easily by the death of roughly 50% of new journals (Umstätter & Rehm, 1984). The reason for this is also very simple; scientists on the search front always want be the first.  Conclusion There has to be improved standards of quality and increasing specialization has to be found in the growing area of informetrics. Better measurements of information and knowledge would be one of the great desiderata. If we remember that in 1963 a first very rough estimation of the amount of information in the Library of Congress was calculated with 1013 bit7.  The new Journal of Informetrics with its focus on “good mathematical (probabilistic) models and explanations of informetric regularities (in the broad sense) and/or papers in which interesting and important data-gathering” comes at the right time, according to our study. The basis of a well known publisher is empirically also very important.  References  Björneborn, L.; Ingwersen, P. (2001). Perspectices of webometrics. In: Scientometrics 50, 65-82.  Bradford, S.C.
