The lazy searcher?

(10)

Good search, wrong database!

• Searching for modern literature (Dorian Gray) in EEBO (Early English Books Online)

• Using Norwegian search terms in English language databases:

– fjellturer and tromsø in Russian State Library Catalog

• Searching for historical topics in a medical database:

– Grønland and colonial history in Medline

• Searching for celebrities in an academic database:

– wayne rooney in Psycbooks

(11)

Fields of gold?

• Using search fields wrongly:

WYR=Unconscious perception: Attention, awarness, and … WAU=forfatter [‘forfattter’ is the Norwegian word for author]

• More than 2000 searches in the subject field (WSU)

• What is a subject?

WSU=Understanding international conflicts: an introduction to theory and history

WSU=speed of processing AND WSU=age-related

WSU=quality

(12)

Boolian confusion

What is the difference between AND and OR?

• sami AND samisk

• roleplay AND rollelek

• practice knowledge OR health

• nursing OR hypochondriasis

(13)

The zero results effect

Goodbye library!

(14)

It’s not them, it’s us?

• User training can be improved

– The importance of language

– Boolean operators

• Do we take their needs seriously?

– Searching is not simple – Are library systems too

complex?

(15)

The next step:

• Focus on searching, logic and critical thinking in

information literacy classes

• Creating a new online course for students

• Raising awareness among

library staff about particular

challenges
