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?
