Subject: small problem reaching elsevier science journals through NCBI

Hello,

This is likely a problem with NCBI […], but I thought you would know better. I am trying to download a journal article linked by the ncbi website... go here:

http://www.ncbi.nlm.nih.gov:80/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=11255015&dopt=Abstract

next: click on the "elsevier science. Full text article" button.

...but the link doesn't recognize my caltech IP , and it asks for a username and password. I can, however, manually go to the elsevier webpage and grab my article (so its not a pressing issue, just an annoyance)

Is there something I can do […] to bypass this login page?

-thank you

Subject: RE: small problem reaching elsevier science journals through NCBI

[…] Thank you for letting us know. Unfortunately we can't solve this particular problem, at least not in the near term.

The publisher's icon appears in the PubMed record for articles in journals for which publishers have provided full-text links to PubMed. This happens […] whether or not Caltech has site-licensed online access for the journal. Caltech […] has not yet been able to negotiate a cost-effective site license for Elsevier's Science Direct product […], although we continue to try.

For many Elsevier journals […], Elsevier provides us at no extra cost what they call Web Editions […] Again unfortunately, there's no way to get […] Science Direct icons in PubMed to link to our Web Editions access, so manual navigation to the desired article is necessary […]

SFX: How does it work?

1. Script:Draws the button.

Gets the resolver URL.

Constructs HTTP GET/POST command.

2. Transport description to the SFX resolver…By clicking on the button.

OpenURL Standardization

Page 29: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

The OpenURL Framework (Version 1.0)

An OpenURL is an HTTP(S) GET/POST based transportation mechanism for ContextObjects.A ContextObject is a construct that describes: One Referent Zero or more other entities that define the

context in which the reference to the referent occurs or in which the transportation of metadata takes place.

Page 30: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

ContextObject

Structure: up to 6 entities Referent (item, subject, article) Referrer (service building the ContextObject) Resolver (service component – link server) Requester (user) Service-Type (type of resolution) Referring-Entity (citing article)

Entities described by up to 4 kinds of descriptors: Id By-Value By-Reference Private-Data

Page 31: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

ContextObject: Examples

Referent described by an Id Journal article: Digital Object Identifier Journal: ISSN Book: ISBN

Page 32: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

ContextObject: Examples

Referent described by Metadata-description Journal article: Journal name, Journal

ISSN, Article title, Author name, Volume, Issue, Page numbers

Technical report: Corporate name, Author name, Report title, Report number

Page 33: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

ContextObject: Examples

Referent described By-Reference Journal article: “Dublin Core” and a

pointer to a Dublin Core description of the article

Book: “MARC” and a pointer to a MARC description of the book

Page 34: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

OpenURL: Why standardize?

Lower barrier for information providers Make it easy to provide OpenURLs

Encourage adoption beyond “Scholarly Information Societies”Create a market in resolvers

Collaborative Acquisition

Valuable Information is Expensive Out of reach to many

Approaches to increase availability Make information cheaper:

Open Archives/Access Initiative Find Information Sponsors

Page 37: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

Collaborative Acquisition

Develop Network of Information Sponsors: National Libraries Governments Private Foundations International Organizations …

Page 38: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

Collaborative Acquisition

Each Organization decides Target group of beneficiaries, for

example: Researchers in India, Africa,… High-school students

Information to sponsor, for example: Medical research literature Space science

Each Organization negotiates own set of Access Licenses with Publishers

Page 39: The OpenURL Framework Collaborative Acquisition of Content Eric F. Van de Velde, Ph.D. Director of Library Information Technology, Caltech evdv@library.caltech.edu

Collaborative Acquisition

Each Information Sponsor Contributes relevant details of its Access

Licenses to a shared database

OpenURL Resolvers use the database Find least expensive method of accessing

particular information for a particular user Note: Importance of federated

authentication (Shibboleth)

Conclusion

This proposal may be too far out, but…It shows what OpenURL can do: Targeted, narrowly focused

information Best source of information Highly individualized information Context-sensitive information
