Exercise 2 / comparison of your searches
Searches
Practical 1:
Conduct your own search (using
keywords from task 1 & 2):
- with Scopus
- Google Scholar
How do these results compare
with your previous searches?
!!! 15
minutes !!!
Comparison of some bibliographic tools (databases),
searched in 2007!
3 search scenarios:
1. 'indeterminacy with regard to performance
practice‘
2. literature about/by one composer: Christian
Wolff (*1934)
3. Finding publications by one scholar: Claire
Taylor-Jay (CTJ)
Comparison of some bibliographic tools (databases)
Criteria:
Number of different
sources/publications.

C. Uniqueness
D. Scope

Conclusions – RILM

RILM only e-resource used here which creates
main entry for multi-authored publications, PLUS
individual items within the volume:

“duplicating” information and increasing the
number of hits

more information/data needs to be browsed

might confuse novice users
RILM
Searching for
Name in [Surname], [Firstname(s)]
e.g.
Claire Taylor-Jay
can be different to
Taylor-Jay, Claire
Search author = AU field
Conclusions : RILM

RILM = only bibliographic tool specialising in
music and providing abstracts



free full-text search = more results
than just on basis of keywords
clearer terminology = good for generic
search terms (“indeterminate music”)
more diverse publications
Conclusions: Music Index

Music Index
- has a fair number of results, often also
including non- mainstream academic
publications
Conclusions : BHI


BHI – lower number of results, but high
accuracy
Offers search in non-humanities but also
has an art database
-> good for interdisciplinary/crossmedia art research
Conclusions : WoK

WoK – is “okay” for non-specialist
database, and can surprise with 1 or 2
unique results
Conclusions: Oxford Music Online (OMO)

Oxford Music Online
– search function to “search bibliographies”
only can help, but search not accurate (e.g.
HELMUTH Christian Wolff, not CW)

Findings 2011


RILM → got many more results, cont.
increase in record as non-commercial
project!
RILM → most diverse number of
publications
Findings 2011 – slide 2


Music Index – seems to have got more
polyglot than in 2007
“people” search option = very successful
Overall conclusions

Searches prove:

To find the whole, systematic
output of publications all possible
tools should be used
Remaining questions

Elsevier's Scopus? (versus World of
Knowledge?)

How would Google Scholar have scored?

Google Books? incl. Magazine contents!

Mendeley ?

Google Scholar Citations?
Searches
Practical 2:
Use the same search terms for searching fulltext of:
- JSTOR
&
- Google Books
How do these results compare? And: how do
the compare to RILM and Music Index?
