PFR textseeka - an OpenURL Resolver

What is an "OpenURL Resolver"?

Put simply, an "OpenURL Resolver" bridges the gap between finding a reference to an item, (article, book, etc.), you want, and being able to find out how you can access it.

Hopefully, there will be a ‘magic’ link, (normally an image, but not always), that takes you to the results page of your OpenURL resolver - this link is formatted according to a protocol known as OpenURL, and the results page is provided by the OpenURL Resolver.

In more detail, the aim of OpenURL Resolvers is to make life easier for you, when you want to get an item, when the item could be:

• in electronic full-text
• in print, in our collection (listed in our catalogue)
• able to be sourced via the Library (either interloans or other means!)

The OpenURL technology tries to side-step the whole process of using the citation information, (for a journal article as an example), to :

• either try your luck, using the DOI or Google search (either of which aren't guaranteed to match your library's access)
  
  
• or use a proper ‘library-style’ approach:
  
  
  1. find the ejournal/source title
  2. confirm whether you are entitled to access the full-text:
     • - then, (if you ARE entitled):
     1. go to the journal homepage
     2. find the correct volume
     3. find the correct issue
     4. locate the article
     • - then, (if you are NOT entitled):
     • seeing if it is listed in our catalogue OR
     • emailing the library to ask us to find it for you OR
     • giving up!

- more information, (intended for PFR staff), is available as a 1.02 Mb PDF (with links).

status

Currently, our text seeker supports in-line OpenURL requests, (version 0.1 and 1.0/Z39.88-2004), as well as requests using DOI or PMID data.

We appreciate your feedback! Please, let us know if there's anything that can be done to improve textseeka.

You can give textseeka a go using:

• the forms page
  
  
• trying one on the sites below - see "where does it work?"...
  
  
• Internet Explorer 7⁺, Firefox 2⁺ or other application (such as EndNote) - read on...
  
  

where does it work?

- with any standard web browser:

• Discovery Tools/databases:
  Web of Knowledge^* - provides access to CAB Abstracts, Food Science and Technology Abstracts, Web of Science, etc.
  N.B. PFR textseeka icon appears on the results page and single citation display example screenshot
  

PubMed, either via a special link, (or more permanently) once you've made changes to your settings via the My NCBI setting for Outside Tool.
N.B. PFR textseeka icon appears only in single citation display, and in different places for Abstract or AbstractPlus... example screenshot

Scirus, once you've made changes to your Preferences via the Library Partners option.
N.B. PFR textseeka icon may appear inconsistently in the results... (linking is done from Scirus, so not sure why) example screenshot


• Publisher's sites:
  HighWire Press hosted titles^* - a PFR textseeka text link appears only in the article bibliographies for articles in CFR subscribed journals...example screenshot
  
  ScienceDirect^* - PFR textseeka icon appears alongside other access options for articles you're not entitled to view...example screenshot
  
  
Springer^* - a PFR textseeka text link appears only for articles you're not entitled to view...example screenshot


• Other sites:
  Ingenta^* - (not at all intuitive) PFR textseeka icon appears only in article bibliographies....example screenshot
  
  

              * if from PFR IP-ranges - either at work, or using CFR remote dial-up/VPN access

- with browser enhancements, you can also use textseeka with:

• Google Scholar (there is an OpenSearch plugin available from this page - see below for browser-specific instructions on how to add this search-engine-in-a-browser...)
  
  
• any web page that contains COinS ("a simple, ad hoc community specification for publishing OpenURL references in HTML.")
  
  
• any Discovery Tools/databases which also use COins, such as HubMed ("An alternative interface to the PubMed medical literature database").

using it to it's full potential

To get the most out of textseeka, you need to set up:

• Internet Explorer 6⁺
• EndNote
• Firefox 1.5⁺ (if installed)
• Zotero - requires Firefox 2⁺ (if installed - an add-on for Firefox)

Browsers

Firefox (and most Mozilla-based browsers)

You can install Firefox, and it will import your Internet Explorer settings. Firefox does not prevent you from using Internet Explorer or any other browser.

	Firefox Browser Add-on The OCLC OpenURL referrer for Firefox: lets users provide their own data for the OpenURL resolver in an easily understood way, (including the size of the image for linking). automatically inserts the OpenURL links, (it will add the links after the page has fully loaded, although sometimes you may need to refresh the page) To set up Firefox for textseeka You need to install the OCLC OpenURL referrer, by following the instructions on the Openly site. Use the following settings under Tools | Add-ons -> OpenURL Referrer: Link Server Base URL: http://lib.crop.cri.nz/textseeka/resolver.php OpenURL version: (preferrably 1.0, which includes journal articles and books, etc.) Display Link as Image setting: (choose one) http://lib.crop.cri.nz/textseeka/images/PFRtextseeka-icon.png :(icon) http://lib.crop.cri.nz/textseeka/images/PFRtextseeka-sml.png :(small) http://lib.crop.cri.nz/textseeka/images/PFRtextseeka-med.png :(medium) http://lib.crop.cri.nz/textseeka/images/PFRtextseeka-lge.png :(large) additional images are shown on another page entirely
	LibX - CFR Toolbar for Firefox versions 1.5+ - 3 (and compatible) Yes, another toolbar... but this one's the best for those doing literature searching on a regular basis. The aim of the LibX - CFR Toolbar is to make it easier for you to obtain items (articles, books, journals) - it is not designed for searching for articles. N. B. You can use the LibX - CFR Toolbar together with the browser plugin shown above - we know of no issues from having these both installed in Firefox. Features: Context menu options Linking is enabled on pages with COinS, DOIs, and ISSNs or ISBNs. Cues are added to pages - this flash demonstration shows how cues work (basically they provide a "cue" that a link has been made for you by the toolbar) It's available from the same page as the Search Engine Add-ons, (below), so please give it a try, see what you think, and let us know.
	Firefox Search Engine Add-ons Firefox 2 + has it's own search toolbar. If you have an extra search toolbar installed already, then this search box can be redundant. To be able to use these "Search Engine Add-ons", you need to add them. To install any Firefox Search Engine Add-ons available from this site, you must click on the image on the left first, and then follow the numbers. To use search engine add-ons, you need to click on the search engine add-on you want then type/paste in the text to search, and press enter.

Internet Explorer

Internet Explorer Browser Add-on We don't recommend the IE version of the "OCLC OpenURL referrer" - please install the LibX - CFR Toolbar for Internet Explorer 6+. LibX - CFR Toolbar for Internet Explorer 6+ This version of the toolbar is well worth installing if you're doing literature searches, (e.g. HubMed), and don't want to install or use Firefox, (though the Firefox version supports more sites, and is easier to install / use). The aim of the LibX - CFR Toolbar is to make it easier for you to obtain items (articles, books, journals) - it is not designed for searching for articles. Features: Context menu options Linking is enabled on pages with COinS, DOIs, and ISSNs or ISBNs. Cues are added to pages - this flash demonstration shows how cues work (basically they provide a "cue" that a link has been made for you by the toolbar) It's available from the same page as the Search providers, (below), so please let us know how it works for you.

Internet Explorer 7+ Search providers Internet Explorer 7+ has it's own search toolbar. If you have an extra search toolbar installed already, then this search box can be redundant. To be able to use these "search providers", you need to add them. To install any Internet Explorer 7+ search providers available from this site, you must click on the image on the left first, and then follow the numbers. To use search providers, you need to click on the search provider you want then type/paste in the text to search, and press enter.

other programs/applications:

EndNote 7⁺

Very good results are obtained with the EndNote OpenURL preferences set correctly: inserts the OpenURL links, but only once you click on Reference | OpenURL link, or use the (right-mouse-click) [context menu] | OpenURL link for each Reference To set up EndNote for textseeka. In EndNote: Click on Edit | Preferences Click on OpenURL You need to make the OpenURL path: http://lib.crop.cri.nz/textseeka/resolver.php You need to change Arguments: ?sid=ISI:WoS to ?sid=ISI:EndNote (- leave the rest alone)

Zotero - requires Firefox 2⁺

Zotero is a freely available add-on for Firefox, to "help you collect, manage, and cite your research sources" from Zotero.org - see their site for more details. Zotero is produced by the Center for History and New Media, George Mason University: . Very good results are obtained with the Zotero OpenURL preferences set correctly provided the reference type for that item is set correctly: activates OpenURL link, but only once you click on Locate, within your Zotero Library, as show below: To set up EndNote for textseeka. In Zotero: Click on Then click on OpenURL You need to make the Resolver: http://lib.crop.cri.nz/textseeka/resolver.php You need to make the Version: 1.0 (- leave the rest alone)

additional ways to use textseeka

Web forms

There are a number of ways to search textseeka, including using:

• the PubMed ID [PMID] for an article
• the DOI for an item
• the citation search for:
  • Journals - provide at least title/issn and year
  • Journal articles
  • Book/Conference Proceeding
  • Book section/chapter
  • Published Patent/Patent Application

The webforms for these searches are on their own page.

details

how textseeka links to items

• Direct access to Article links aren't always present.

  We currently do direct linking in 3 main ways:

  1. using OpenURL DOI data, extracted from the OpenURL requests itself, (but unconfirmed).

  2. using CrossRef, which provide an API to do forward, (citation -> DOI), and reverse, (DOI -> citation), lookups

     CrossRef includes the main publishers we deal with:

     • JOHN WILEY & SONS

       www.interscience.wiley.com

       www.wiley.com

       soon to include BlackwellSynergy www.blackwell-synergy.com

     • ELSEVIER

       (Academic Press, Cell Press, Churchill Livingstone, Elsevier Science, Hanley & Belfus Inc., The Lancet, Mosby, Spektrum, Urban & Fischer Verlag, W.B. Saunders)

       www.elsevier.com

     • AMERICAN CHEMICAL SOCIETY (ACS)

       www.acs.org

     • CSIRO PUBLISHING - recent articles

       www.publish.csiro.au

  3. using a rules-based method (- this is what needs further work).

     We need rules for:

     • ANSI titles - done - PDF

     • BMC titles - done - PDF, HTML, and volume level (no issue level, as articles have their own "article number" within a volume)

     • Royal Society of New Zealand titles - done - issue level only

     • Elsevier:ScienceDirect titles - done - issue level only (not really necessary, but good if CrossRef is unreachable)

     • ProQuest titles from the Agricultural and Biosciences collections - done - linking to their OpenURL resolver, and using an article search (their OpenURL can be unreliable, i.e. fail to find a result!)

     • Blackwell-Synergy titles - done - linking to their OpenURL resolver (not really necessary, but good if CrossRef is unreachable)

     • Ingenta titles - done - linking to their OpenURL resolver

     • Springer titles - done - linking to their OpenURL resolver (not really necessary, but good if CrossRef is unreachable)

     • Taylor and Francis titles - done - linking to their OpenURL resolver (not really necessary, but good if CrossRef is unreachable)

     • NRC Research Press titles - done - linking to their OpenURL resolver (not really necessary, but good if CrossRef is unreachable)

       Do not confuse NRC with other Canadian Journals of.

     • Old CSIRO articles done - article level using a CSIRO journal search (new articles use CrossRef DOIs)

     • Highwire & Highwire-hosted titles - needs testing, all titles not yet identified

why DIY (Do-It-Yourself)?

Initially, there was no intention to build textseeka - the idea was to use an open source/free OpenURL resolver... I tried, but it didn't work out.

So, you may wonder why textseeka was built, when we could buy off the shelf.

Here's some of our reasoning:

• not tied to any specific vendor, agent or product
• no ongoing fee each year
• tie-in with other products, such as the LibX toolbar, browser add-ons, and web-forms on our site.
• we prefer to be able to do the Knowledge Base updating, etc. directly ourselves (partly because we already have an ejournal A-Z within our Library catalogue)
• we control the presentation, etc. (down to the nitty-gritty)
• we know exactly where the target links go - mostly to publishers, (not agents)
• we can specify targets/publishers which may (or may not) be supported on vendor platforms, such as the Royal Society of New Zealand
