Overview
Problems being solved SFX (Open URL Linking) MetaLib (Federated Search) EZproxy (Remote Access) Next steps Questions
The problems at hand
Growth of library’s electronic resources Approximately 32,000 electronic resources Electronic resources expenditures $3.2 million 38.0% of our total collection budget
Patrons need to find known items (SFX) Discover appropriate resources (Metalib) Seamless remote access (EZproxy)
What we were doing
NUcat - online library catalog ER (Electronic Resources) database Remote access
Proxy Server Proxy CGI VPN Client
What we will be doing
NUcat - online library catalog SFX - item level article access MetaLib - federated search interface EZproxy and VPN - remote access
What does SFX do?
FirstSearch EBSCO
OpenURL resolver
How does SFX do that?
Through OpenURL A standard means for identifying content
Provides a mechanism for encoding a citation for an information resource, typically a bibliographic resource, as a URI URL DOI
What can it link from and to?
OPAC (online public access catalog) Abstract/index databases Full-text databases OpenURL-enabled resources
Citations Table of contents Web forms Repositories
OpenURL resolver
How does this work?
Redirection through a resolver Resolver interprets data
Digital Object Identifier (DOI) A URL encoded with metadata about the resource
http://hopper.library.northwestern.edu/sfx?genre=article&issn=0100-0293&volume=32&issue=1&spage=55&epage=76&date=2003&aulast=Gergenplotz&aufirst=Joe
Locates appropriate copies

Let’s take a look…
SFX Screen Logic
FindIt@NU will always display in active sources
The service menu will always appear if FindIt@NU button is clicked
Answers Online will always display Downloading to RefWorks and EndNote
will always appear as an option
Three screen types
When full text is available
When a print copy is available
When Interlibrary loan is the only option
But…
As nice as SFX is, it is just a stop on the destination to federated searching
OpenURL resolver
I think that an abstract of that article on usability testing in
Tonga was in Expanded Academic but there was no full text! I need to finish my
research today!I wonder if I can get the full
text somewhere?

Federated search answers a different type of question
I can never remember where the best place is to find articles on
usability
I know, I’ll use that new metasearch product we just
installed
Merged results list
EBSCO
ProQuest
FirstSearch

Where can I find information on that
usability testing research in Tonga? If I
could find those articles, my research would be complete!

EZproxy (remote access)
Vendor provided solution Replacing Proxy Server and Proxy CGI Using LDAP for identity management Using “nuSchoolAffiliations” to determine
appropriate access vs. IP address SFX and MetaLib automatically route
through EZproxy if needed.
Summary
SFX provides the article resolution engine MetaLib provides the interface and engine for
federated searching EZproxy is replacing existing proxy servers
Works with SFX and MetaLib to provide seamless off-campus access
Next Steps
SFX in production and is available through target resources
EZproxy is in production and is invoked when needed by applications.
MetaLib coming soon, links on library home page and ER sites
Enhanced versions of SFX/MetaLib by Winter quarter
ER phased out by next summer
