  1. SCART 2005 HIV/AIDS information on the World Wide Web and in the ITM library Dirk Schoonbaert ITM Library August 24, 2005

  2. Major themes • Internet information resources. • HIV/AIDS resources on the WWW. • Accessibility of electronic journals.

  3. Too much information … • Many millions of webpages are available on the Internet. • There are huge differences in quality, relevance, reliability. • Every day thousands of pages are added, updated, removed or have their address (‘URL’) changed.

  4. … Too little information • Not all data that are published on paper or in electronic databases are also available on the World Wide Web (WWW). • Not all electronic resources on the WWW can be accessed by everybody (intranets!) or for free (commercial services!).

  5. Web indexes … Text-based machine-generated indexes: generally so many pages are found it’s impractical. Luckily relevance-ranking is improving all the time. E.g.: • Google [www.google.com] • Google Scholar [scholar.google.com] • All the Web [www.alltheweb.com]

  6. … Web directories Subject-based human intellectual endeavour: hierarchically structured, often evaluated, annotated. E.g.: • General, comprehensive: Yahoo [dir.yahoo.com], Open Directory Project [www.dmoz.org] , … • Biomedical & health related: HealthWeb, MedlinePlus, Excite – Health, … • Covering specific topics, e.g. HIV/AIDS, sexually transmitted infections, …

  7. HIV/AIDS websites … • AIDSinfo (NIH) • The Body • Global Fund to Fight Aids, Tuberculosis & Malaria • HIV InSite Knowledge Base • HIV Medicine • International Association of Physicians in AIDS Care (IAPAC)

  8. … HIV/AIDS websites • Johns Hopkins AIDS Service • Medscape HIV/AIDS • Telemedicine.itg.be • UNAIDS/ONUSIDA [news, statistics, publications, …] • WHO: HIV-AIDS pages • … • Journals: AIDS, JAIDS, JIAPAC, …

  9. Bibliographic databases • Selective - e.g. Medline/PubMed: over 4,000 different biomedical journals, but no books or ‘grey’ literature are included. • Trustworthy: peer reviewed publications = published research outcomes + official public archive. • No full-text articles: bibliographic descriptions and abstracts only. [+ increasingly: ‘linkouts’]

  10. Databases in the ITM library • OVID/SilverPlatter ERL Server: • ITM catalogues (library collections) • ITM databases (specific subjects: endemic diseases, …) • International databases (on subscription) • Other external databases (available on WWW): • PubMed [www.pubmed.com](free for all) • ISI Web of Knowledge (current contents, science citation index + journal citation reports: impact factors!)

  11. Electronic journals • Originally ‘experimental’ electronic-only journals + ‘preprint archives’. • Electronic adverts for printed journals. • Contents: tables of contents (TOCs) => abstracts => full-text (HTML + PDF). • Additional functionality: searching, alerts (TOCs or keywords), linking with databases, fast electronic submission and peer review, multimedia content, online-only content, … • Electronic edition >> print edition (e.g. BMJ).

  12. Pricing policy • Online access free for all: EID; MMWR; … • Online access free for all after some delay: Proceedings NAS USA; ASM journals; … • Online access included in print subscription: Lancet, New England Journal of Medicine, ... • Online access as paid supplement to print subscription: TM&IH. • Online access only at reduced price: ASM journals (e.g. 90%). • Package deals: Science Direct [Elsevier], Blackwell Science Collection, Ebsco, ….

  13. New initiatives … • HINARI – Health Internetwork: special access conditions for developing countries (free or lower price). • PubMed Central: free access to established journals after 6 months. • BMC - BioMed Central: a series of freely available new electronic-only peer reviewed journals, financed by author fees. • PLoS - Public Library of Science: ‘author pays’ journals, e.g. PLoS Biology, PLoS Medicine, ...

  14. … New initiatives • SPARC – Scholarly Publishing & Academic Resources Coalition: offer new alternatives for expensive journals. • SCIELO: free Latin American journals (BIREME). • OAI - Open Archives Initiative: self-archiving, using universal interconnectivity protocols. See e.g. DOAJ & DOAR directories (Lund University) • … [URLs: see ‘http://lib.itg.be/journals.htm’, section 2 & 3]

  15. How to find the actual printed documents in the ITM library • Journal articles • Copy or print the bibliographic description ( = database record). • The ‘source’ (‘SO’) field contains all essential data! • Verify if the journal is available in the library (‘LHM’ field or periodicals catalogue). • Journals are on the racks in alphabetical order: current issues are on the upper floor; older volumes on the lower floor.

  16. How to find the actual printed documents in the library - 2 • Books and book chapters • Copy or print the database record. • The ‘Code’ (‘CD’) and ‘Publication year’ (‘PY’) fields are crucial! • Books are ordered by subject (= ‘Code’) on the shelves of the upper floor (classification: see handout or search the ‘ITG Book and Document Holdings’ for specific titles).

  17. How to find the actual printed documents in the library - 3 • ITM Dissertations: • Printed lists or database; use the ‘series number’! • Documents to be asked for at the counter. • Grey literature: • ‘ITM Books …’ database; use the ‘series number’! • Documents to be asked for at the counter. • Reference: • See reference section next to the library PCs (a lot of this material is freely available online).

  18. ITM library linking pages • http://lib.itg.be/biblinks.htm links to selected biomedical websites • http://lib.itg.be/journals.htm links to selected journal websites • http://lib.itg.be/ebooks.htm links to selected electronic books • http://lib.itg.be/datab.htm links to selected databases
