• A&I Services for Content Discovery
–Why Indexing?
–Types of A&I services
–How does the process work?
• DOI (Digital Object Identifier) as Discovery Tool

Why is indexing essential?
• Users are no longer browsing in a library
• Usage comes from on-line indexing services, not from users browsing
publisher databases
• Publishers need to be well-represented in all important indexing
services
• Google is by far the most important
• Discipline specific services are also key
5
Type of Indexing Services
• Interdisciplinary (Thomson Reuters (formerly ISI), Google, Scopus) vs.
Discipline specific (PubMed/Medline, ChemAbstracts, ADS
(astronomy, physics), MathReviews, Philosopher’s Index, ERIC
(education))
• Selective (Thomson Reuters, PubMed/Medline) vs. All-inclusive
–Criteria: quality of articles (content and publication), quality of authors,
(# publications, # citations), quality of editorial board, timeliness of
publication)
• Indexing-only vs. Reviewing/Abstracting
6
Springer A&I Policy
• Springer A&I directly supports ISI, PubMed, and the priority indexing
services.
• Smaller indexing services are handled by individual publishing editors.
• All metadata transfer to such services is handled by Springer A&I in
coordination with Springer Heidelberg

What is a DOI?
• A digital object identifier is an alphanumeric string created both to:
–Uniquely identify a content work, and to
–Serve as a stable link to that content’s digital location
• A DOI stays the same regardless of changes in ownership or location
because it is just the name used to look up an address in an easily
updateable directory
DOI -- 10.1007/s00261-008-9441-3
DOI -- 10.1134/S1063771008060018

International DOI Foundation
• IDF oversees central DOI system and promotes DOI as a standard
• Provides the organizational infrastructure that ensures persistence and
interoperability
• Includes Eight Registration Agencies:
– European Union Office of Publications
– TIB (Technische Informationsbibliotek)
– R. R. Bowker
– Nielsen Bookdata
– CAL (Copyright Agency Limited, Australia)
– mEDRA (multilingual European Registration Agency)
– Wanfang Data (an affiliate of the Chinese Min. of Sci. and Tech.)
– CrossRef

Why Be in CrossRef?
• CrossRef (founded 2000) is the largest DOI registration agency
• CrossRef participating publishers collaborate on digital infrastructure
(organizational and technical) for researchers
• Protect users from dead external links and Error 404 messages
• Integrates with Open URL
• To get persistent IDs for content
• To drive more traffic to content
• To turn references into hyperlinks
• To pull in cited-by links (what other publications cite this content)
12
Content Types for DOIs
• Books
• Standards
• Proceedings
• Images
• Figures
• MRW entries
• Datasets
• Working Papers
• Dissertations
13
CrossRef Implementation
• Publishers deposit DOIs and metadata to enable inbound linking
–As soon as content is registered in CrossRef, it becomes visible for
linking by other participants
• Create outbound links from references by querying the CrossRef
metadata database
• Cited-by: Allows any member publisher to retrieve cross-publisher citedby information and implement a “what cites this” feature
–Helps the academic publishing community track and preserve the
scholarly citation record

Impact Factor Calculation
•
•
•
Nc = Number of citations from year y to articles published in year y-1 and y-2.
•
IF = Nc / (N1 + N2)
N1 = Number of articles published in year y-1
N2 = Number of articles published in year y-2
