FINDINGS

:

GS useful search engine

BUT

:

- no. of ref. reduced to

1000

for certain keywords

- ref. of GS are not the versions of bibliogr. DB

BUT

present., books, conf. papers, citations…

- advanced search, export and duplicate detection, limited;

C

ONCLUSION

&

FINDINGS

- results conform to the specificity of the DB

- both domains of geography are well represented

- geographers could use GS as a complementary tool

for their bibliographic research

- to find grey literature;

Q

UESTIONS FOR MY FUTURE STUDIES

:

- HOW/DO geographers use the literature found in DB

 active bibliographical research with one

geographer/field on an actual research?

- Percentage of grey literature in GS? Is this literature

used(reports, conf. presentations, etc) by

geographers?

- Human or Physical Geography better represented by

GS?
