– see what you can contribute to the field
• types of literature – books
– review articles
– full-length papers
– letter articles
– Proceedings
– Nature / Science articles („Big Bang“)

ISI Web of Science
• all the “official” data accumulates here
• extensive information on
– WHAT papers exist on a topic
– WHO is publishing &
– WHO is citing H index
– WHERE is the research published
– HOW MUCH is this recognized Journal Impact Factors
– WHEN does publication activity reach top timeline statistics
– WHERE do people (authors, citing) come from
– WHAT networks exist among them self citation metrics

ISI Web of Science
• What can it do for me? – SEARCH
• comprehensive search capabilities (topical, time-resolved, geographic, …)
• scriptable as news feed / e-Mail alert
– IDENTIFY connections between different works • for- / backward referencing
• geographical connections
– ALERT you when something new comes up
– PERSONALIZE science • who is working in the field
• citation metrics (H index)
– MEASURE journal “performance” • Impact Factor

preprint servers - arXiv
• important scientific role: preprint servers
– all types of articles available
– uploaded prior to peer-review
– freely accessible without subscription
– might only be feasible to experienced scientist due to 'everyone can publish' philosophy → high number of papers might be confusing to beginners!
– most famous: arXiv (Cornell Library), esp. category physics.optics

Literature management
• now you have
– gained an overview by looking into a basics textbook
– got deeper by crosschecking original references therein
– indentified people / research groups in the topic
• stay up to date with e-alerts & custom news feeds
HOW TO KEEP TRACK OF
ALL THOSE PAPERS???

Literature management
– use bibliographic management software!
• What is it?
– BMS manages all your references in a database
– eases citation of a paper by integration into word processing software ('click + cite')
– provides tools for annotating, grouping, sorting & searching papers you work with
• most prominent: BibTeX (quasi-standard), EndNote, Mendeley, Qiqqa, see list here

Literature management
• How does it work?
– publishers provide reference data for a paper
– this is imported into BMS which does the rest

Literature management
• Annoyed of importing the bibtex data? Looking for a 'one click' solution? → Try Mendeley
– can import ref data directly from a website!
– can scan a PDF automatically! (Drag & Drop)
– can synchronize among different PCs & web via client ↔ server communication
– synchronizes with a bib file automatically if you wish!
– brings MS Word & Open Office plugins for direct citation (very easy!)
– it's truly amazing... :-)
