In scientific research, the development of digital media has revolutionized the documentary landscape. The objective of our work was to identify the influence of the development of electronic scientific information and Open Access on the use and dissemination of scientific publications in Geography. Our doctoral dissertation is organized around two main matters: on the one hand, bibliographic research tools and their coverage that influence the use of documents, and on the other hand, the dissemination and visibility of the results returned by these bibliographic research tools. Different methodological approaches have been adopted and the results are presented in two parts and five chapters. In a difficult financial context, linked to the permanent rise in journal prices and to increasingly restrictive editorial policies, the question of the effectiveness of commercial bibliographic databases (such as WoS, Scopus, GeoRef) against the "free" search engine GS, has been the subject of many publications. However, as far as geography is concerned, there is little data available on the effectiveness of GS as a bibliographic research tool and means of dissemination of scientific publications. In our work, as much for keyword searches, as for its coverage in theses bibliographies or for its coverage in a selection of publications from ULiege geographers, the results numerically place GS largely at the top of the list of the bibliographic tools analyzed. The search engine finds many references, whether in Physical Geography or Human Geography. Generally, GS completely covers the contents of the other studied databases, with some exceptions for GeoRef, a tool that is specialized in Physical Geography. Regarding the visibility of the scientific literature produced by the geographers of ULiège, we have noted an excellent performance of GS, followed by Scopus, WoS and GeoRef. The role of the ORBi institutional repository in the visibility of the ULiège publications via GS was questioned. The references are all visible and accessible to researchers via GS thanks to ORBi’s harvesting, even if the performance of GS would in any case be greater than that of the databases without the contribution of ORBi. The cartographic representation of downloads made from ORBi and a statistical approach to data allowed us to conclude that the language of references, the location of countries on the different continents, as well as the membership of the countries that make the downloads to the French-speaking community positively influence the number of downloads. Developed French-speaking countries as well as those in the process of development are the largest users of these publications, of which a large percentage is French-written. In conclusion, bearing in mind the fact that GS is only apparently "free" and that there are economic and social implications to its use, our results allow us to argue that the search engine can be a solid alternative to classical commercial databases in Geography. Furthermore, the development of digital media offers the academic world the opportunity to regain, at least in part, the dissemination of research results. Thus, making available the publications in institutional repositories, which are part of the Open Access movement, improves their distribution regardless of the type of document or language of publication.

Our study aims to establish the profile of the bibliographical resources used by PhD students in geography. We also verify in which proportion researchers use documents specifically covered by the search engine Google Scholar (GS), and three commercial bibliographic databases (DB): Web of Science (WoS), Scopus (multidisciplinary databases) and GeoRef (specialized in geosciences). We choose to work on a sample of three dissertations presented in the Uliège(Belgium) Department of Geography during the 2014-2015 academic year, respectively in Climatology, Tourism and Geomatics. In order to achieve our main objective, the document types, years of publication, and the language of the references, present in the bibliographies of the three theses were identified and analyzed. The follow-up of Bradford's Law, according to which 80% article citations come from 20% journal titles, was also verified. We performed searches in order to verify to which extent researchers' citations are covered by GS and the DBs mentioned. The percentages of documents (all types combined) and journal articles covered by each bibliographic tool were calculated. The results indicate that several types of documents are cited by geographers, and differ depending on the orientation of the research subject to SS&H or S & T. However, most of the citations,73 %, in the three dissertations correspond to journal articles. Books and book chapters follow, and to a lesser extent grey literature (conference proceedings, theses, reports, unpublished works) is much less representative with values <5%. Bibliographies of these three theses don’t follow Bradford's law, higher percentages of journals are required to reach 80% of the articles cited in each thesis. Our research shows that GS outpasses the other DB being the only tool to provide access to other types of scientific literature, such as conference proceedings, theses, reports and unpublished works. In terms of indexed references, GS is the most comprehensive bibliographic tool, having found the majority of references searched with values close to 100 % for the three bibliographies, all documents types combined. Taking into account the results of our analysis we can conclude that, in terms of content, GS constitutes a solid alternative to commercial databases. [less ▲]

This research aims to evaluate the interest for geographers to use Google Scholar(GS) over the commercial databases Web of Science (WoS), Scopus (multidisciplinary databases), and GeoRef (specialized in geosciences). To achieve our main objective, we performed searches in order to verify to which extent researchers' citations are covered by the search engine and the three commercial bibliographic databases mentioned. Our sample consists of the citations of three dissertations in Geography presented in the Uliège (Belgium) Department of Geography during the 2014-2015 academic year, respectively in Climatology, Tourism and Geomatics. In order to have an overview of the results’ “overlap” for the bibliographic tools, and their "unique" contribution, Venn diagrams were constructed for each thesis. The Venn diagrams indicate that GS finds almost all bibliographic references and returns the greatest number of "unique" results. The “overlap” rates between the commercial databases is very high and GeoRef stands out with very low results. GS is an important and rich complementary tool, with a more varied panel of publishers, languages and countries of publication. [less ▲]

This study aims to highlight what benefits, if any, Google Scholar (GS) has for academic literature searches in the field of geography, compared to three commercial bibliographic databases: Web of Science (WoS) and FRANCIS (multidisciplinary databases) and GeoRef (specialized in geosciences). To ensure a valid comparison, identical bibliographic searches were applied using each of the four bibliographic tools. To exclude automatic variations of the ten keywords tested, they were placed between quotation marks and searched only in the “title” field of the respective search tools’ interfaces. The results were limited to bibliographic references published from 2005 to 2009. In order to assess the repeatability of the results, the exact same process was repeated monthly between November 2010 and July 2011. Initially the whole set of results was analyzed, after which the search results for two keywords (selected since they yielded a manageable number of results) were studied in more detail. The results indicate that GS search results show a large degree of overlap with those of the other databases but, moreover, yield numerous unique hits, which should be useful to researchers in both the fields of human and physical geography. GS leads the other tools widely on number of results, independently of keyword, subfield, year of publication, or time of search. [less ▲]

This study focuses on four bibliographic tools and aims to highlight what the use of the Google Scholar search engine can yield, in comparison with three commercial bibliographical databases: the well known multidisciplinary database Web of Science (WoS); GeoRef, a specialized data base in geosciences; and FRANCIS, which includes international geographical bibliography. To identify the bibliographic references published yearly between the years 2005 to 2009, ten keywords placed between quotation marks have been searched through the title field of the search tool interfaces. On a monthly basis, from November 2010 to July 2011, an identical process was repeated to get some information on the repeatability of the searches. Initially the whole set of results was analysed, and then the search results of two keywords were studied in more details. The results indicate that GS provides a high overlap with the search results of the other databases, but also yields numerous unique hits. Moreover, it seems that it is also able to find diverse types of literature, while the others are more specialized. [less ▲]

Set up by the University of Liège, ORBi (Open Repository and Bibliography) knew a lightning increase of the online posted references since its creation in 2008. The official launch took place on November 26th, 2008 and after considerable efforts on behalf of the team which manages the tool, and researchers who introduce themselves their publications, the contents of the repository managed to reach a value of 64245 references among which 38670 with full text. Working for the Library of Geography of the University of Liege, I found interesting to analyze the number of visualizations and downloads of the references (2005 to 2007) posted online by the ULg geographer’s, and the population interested in this literature. The highlight is on WHO and WHERE are the internet users visualizing and downloading ORBi references from? In order to detect the population using this scientific literature, we analyzed the user IP and their distribution in the world. The data was obtained from a MaxMind database. The type of population using this scientific literature: researchers, individuals, public or private companies was also determined. [less ▲]

Nowadays, analysis of bibliographic databases is a current practice, especially the comparison between traditional, commercial databases and search engines as Google Scholar that has wind right aft. A great deal of researchers analyzed the contents or the citations system of various databases. Some compared the contents of several databases, for specific scientific domains, searching by author (Mikki, 2010; Cecchino, 2010) or keywords (Falagas, 2008). There are no studies concerning the precise domain of geography. This study covers bibliographical databases specialized in geography (physical and human) and Google Scholar search engine. This analyze will point out to geographers what a research in Google Scholar search engine can offer, regarding exclusively contents, in comparison with traditional databases: WOS, Francis and Georef. This analysis does not aim to underline the difference of databases features, but to show what a research in certain databases can bring, from the point of view of contents. To perform this study, we use keywords (in English) and establish them for the physical and human geography according to actual subjects of the respective fields. The research will bring new concrete results given that no comparison of this type was led between the traditional databases used by geographers and Google Scholar. We also hope to give an idea of the possible evolution of the contents for Google Scholar search engine during the determined period of our study. [less ▲]

Set up by the University of Liège, ORBi (Open Repository and Bibliography) knew a lightning increase of the deposits since its creation in 2008. The official launch took place on November 26th, 2008 and after considerable efforts on behalf of the team which manages the tool and researchers who introduce themselves their publications, the contents of the repository managed to reach a value of fifty thousand seven hundred references among which thirty thousand four hundred with full text. Working for the library of Geography of the University of Liège, I found interesting to bend over the "statistics" supplied by ORBi, concerning the number of visualizations and downloads of the references deposited by the geographers of Liège. On base of the statement of various "statistical" data and the analysis of these data, I try to determine if the deposit of the scientific works in ORBi increases - or may increase the visibility of the scientific works of the geographers from Liège.
