Astronomy libraries - your gateway to information
- 1. Astronomy Libraries - Your Gateway to Information Uta Grothkopf ESO Library esolib@eso.org
- 2. Overview • Librarians and what they can do for you • ADS and arXiv: tips and tricks • Electronic journals, Open Access • Problems with e-publications • Cooperation between librarians and astronomers
- 3. Basic Skills Information Literacy Science: surplus of information, not shortage • Know what to read • Construct your search strategy • Current awareness Computer Literacy Hardware, software, network technology • Know your tools • Know your sources • How to access them (office, home, travel etc.) Critical Thinking Skills Is my search result correct and complete?
- 4. Information Fluency Computer Literacy Information Literacy Critical Thinking Skills Source: Pat Viele, Physics & Astronomy Librarian, Cornell University
- 5. What Librarians can do for you • Provide access to print and electronic collections: • books and journals (also when through ADS) • databases, link collections, repositories • Locate resources not immediately available • retrieval systems • networks of librarians • joint collections, knowledge, and ideas • Library as meeting place • ‘science coffee’, (in)formal discussions • Web 2.0 / Library 2.0 • blogs; RSS; interactive; social networking .... or walk into the library office • Librarians as research catalysts • provide research assistance, assist with finding quality information resources, tips & tricks
- 6. The 2 Big Ones in Astronomy • NASA ADS (Astrophysics Data System) • arXiv.org e-Print archive ‣ www.adsabs.harvard.edu/ ‣ arXiv.org (astro-ph) ‣ published literature + preprints ‣ preprints (various versions) ‣ from publishers + authors ‣ posted by authors ‣ myADS notification service ‣ e-mail listings, RSS
- 7. NASA ADS • largest digital library in astronomy, several mirror sites around the world • used almost daily by majority of astronomers • collection of links to articles (2-3 most recent years: subscription needed) • Special features include: ‣ 1st author searches: ^

- 22. Databases beyond ADS and astro-ph/arXiv SPIRES-HEP • www.slac.stanford.edu/spires/hep • Stanford Public Information System • SLAC, DESY, Fermilab • bibliographic info in high-energy physics • full-texts from arXiv and others
- 23. Databases beyond ADS and astro-ph/arXiv Google Scholar • scholar.google.com • free research tool for scholarly literature + citations • conf. proc, books, repositories • good for correcting misspellings • might have duplicates • what sources are searched? • Google PageRank
- 24. Databases beyond ADS and astro-ph/arXiv ISI Web of Knowledge (Thompson Scientific) • commercial • consists of Web of Science (citation db), analytical tools, e.g., Science Citation Index (SCI), Journal Citation Reports (JCR) Citation overlap ≈ 60% Scopus (Elsevier) • commercial • 15,000 peer-rev STM & social sciences journals • abstracts + citations • tools to search, sort, export • email + RSS alerts

- 26. Journals • Core journals in astronomy: A&A AJ ApJ / ApJS MNRAS PASP ESO AAS RAS ASP • Subscription-based, with delayed Open Access (2-3 yrs.) • As of mid-2009: print + electronic • Librarians pay, negotiate licenses, provide access, troubleshoot • The Future: from static journals towards virtual journals / databases
- 27. Open Access • Make publicly funded literature available to everybody OA • No subscription fees • Archive final version, with or without journal layout • Author self-archiving or repositories (arXiv) or Open Access Publishing (retrievability & preservation !)
- 28. Open Access Grothkopf & Erdmann: Open Access — State of the Art IAU Information Bulletin July 2008 www.iau.org/science/publications/iau/information_bulletin/ OA not for free Reader → author Subscribers → sponsoring institutions
- 30. Problems with Online Documents • Long-term access ‣ Archiving: what, where, who? ‣ Preservation: perpetual access, migration to newer formats, metadata, ownership of content, embedded links (inside and outside) • Completeness of digitized material ‣ errata, news, advertisements, columns, letters, front matter, legible figures and graphs, obituaries.... • Deleted items ‣ Journals: plagiarized articles ‣ Wikipedia: ceased projects ‣ Mailing lists, blogs: comments and contributions • Broken links ‣ URL → URN / DOI
