Information challenges for
academic research
• Being more sure not to miss something essential?
– Systematically using subject-specific databases
• Getting access to full texts?
– Search engines and beyond
• Coping with information overload?
– Using reference managent software like Zotero or Citavi
• Citing and respecting intellectual property rights
− an aspect of Good Scientific Practice
• Publishing Open Access!?

Informing – Points to survive
1. Orientation before searching.
Use subject gateways, reference
works and your local library!

subject-specific databases
Web of Science with Science Citation Index
- interdisciplinary! Who cited a specific document?
How much is a document cited?

Differences
Seach engines Subject databases
• Interdisciplinary sources
• Widely intuitively to use
• Full text often searchable
• Rarely intellectual indexing
• Abbrevating of search terms
automatically („stemming“)
• Search philosophy: Best hits,
relevance ranking
• Good for subject-specific searching
• Sophisticated stragegies for
searching possible
• Full text not included in search index
• Partially intellectual indexing with
descriptors or integrated thesaurus
• Abbreviating search terms with
wildcard symbol (often *)
• Search philosophy: Exact hits,
Boolean combination of search terms
Use diverse databases and search engines!

Informing – Points to survive
1. Orientation before searching.
2. Don‘t trust only one information source.
3. In case you are asked for your login or for your credit card,
remember the library …
4. When searching: „Bulls*** in, bulls*** out.“
Think about search terms you use and their
variations and synonyms.
Poorly chosen search terms bring poor search
results. Too general key words lead to too many
hits from which often only a fraction is useful;
when using too specific key words, important
information might not be found.

Basic rules for citing
1) Used sources have to be quoted.
2) Position of references has to be without any doubt.
3) Cited sources have to be traceable because of bibliographical
description.
4) Consult the original document of your sources!
Don‘t use a citation from a paper without looking at the
original document of the citation.
Avoid secondary citations!

At the end something general
Some general hints and key competences when managing
information
‣ Be prepared for constant change.
‣ Know your skills and limits!
‣ Tolerate ambiguity and differences.
‣ Don‘t give up too early.
‣ Be aware that every fact is the result of an act, that information
has been created by somebody with a certain purpose.
