Brief Overview Session 2: Exercise 2 / comparison of your searches Practical 1 Comparison between various resources Search Scenarios and hints Practical 2?

Exercise 2 / comparison of your searches
4
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 !!!
5
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: A.Relevance. B.Diversity C.Uniqueness D.Scope Number of different sources/publications. Unique items for a particular database -> why important? a)range of years of coverage b)range of languages

23
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
24
RILM Searching for Name in [Surname], [Firstname(s)] e.g. Claire Taylor-Jay can be different to Taylor-Jay, Claire
25
Search author = AU field
26
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
27
Conclusions: Music Index Music Index - has a fair number of results, often also including non- mainstream academic publications
28
Conclusions : BHI BHI – lower number of results, but high accuracy Offers search in non-humanities but also has an art database -> good for interdisciplinary/cross- media art research
29
Conclusions : WoK WoK – is “okay” for non-specialist database, and can surprise with 1 or 2 unique results
30
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 )

39
Findings 2011 RILM → got many more results, cont. increase in record as non-commercial project! RILM → most diverse number of publications
40
Findings 2011 – slide 2 Music Index – seems to have got more polyglot than in 2007 “people” search option = very successful
41
Overall conclusions Searches prove: To find the whole, systematic output of publications all possible tools should be used
42
Remaining questions Elsevier's Scopus? (versus World of Knowledge?) How would Google Scholar have scored? Google Books? incl. Magazine contents! Mendeley ? Google Scholar Citations?
43
Searches Practical 2: Use the same search terms for searching full- text of: -JSTOR & -Google Books How do these results compare? And: how do the compare to RILM and Music Index?
44
