OpenURL Linking: the Academic Library Experience

  1. 1. Resource Integration through Open URL Linking Charleston Conference November 2003
  2. 2. John McDonald, Caltech Deborah Loeding, H.W. Wilson Jenny Walker, ExLibris Harry Samuels, Endeavor Speakers Charleston Conference November 2003
  3. 3. An Open URL is a common standard for identifying documents. Open URL compatible publishers use a standard formula to construct the address of any piece of text. What is an Open URL? Charleston Conference November 2003
  4. 4. How can students/patrons use your resources if they don’t know they exist? Open URL links the search to the sources! Better Utilization of Electronic Resources Charleston Conference November 2003

  6. 6. SFX at Caltech <ul><li>Why did Caltech choose SFX? </li></ul><ul><li>What is enabled at Caltech? </li></ul><ul><li>How does it work? </li></ul><ul><li>What were the issues surrounding release of SFX to the campus? </li></ul><ul><li>How do our users like it? </li></ul><ul><li>How hard is it to maintain? </li></ul><ul><li>Other frequently asked questions... </li></ul>
  7. 7. Why SFX? Reference Linking :  Allows researchers to seamlessly transition from one information resource to another, easily linking them to full-text articles, to follow citations, or to find more information about the author, resource, or topic. Context Sensitivity : Links that are presented to the user are determined by the journal and are specific to an institution's collections. Local Control : Library staff determine the best choices to present to the user.
  8. 8. SFX'd Resources at Caltech <ul><li>SFX Sources </li></ul><ul><li>Now : All major bibliographic databases </li></ul><ul><li>Not yet : OPAC (Innopac)   </li></ul><ul><li>SFX Targets </li></ul><ul><li>Fulltext Journal Publishers : All major publishers! Over 80 publishers and a total of 4105 journals (over 96% of our serial collection) </li></ul><ul><li>Other Bibliographic Resources :   ILLIAD Document Delivery System, Local OPAC (Innovative), Feedback Form, Web of Science, PubMed </li></ul>
  9. 9. SFX in ACTION <ul><li>Here are a few examples of how SFX works, in real life....Let's start in the Web of Science , do some searching, get some articles, see what our other options are... </li></ul>
  10. 10. SFX in ACTION <ul><li>Here’s another example…What goes well with beer? Let’s search Grilling and Beef…. </li></ul>
  11. 11. SFX Release Issues <ul><li>When to release?   We wanted to wait to release until after we had a &quot;critical mass&quot; of Sources and Targets.  This would make the system seem like an overwhelming improvement and not resource-specific.  CLS thought it was essential to have Web of Science & OVID as Sources and it was important, though not essential, to have Innopac as a Source.  </li></ul>User Education Issues:   Caltech decided to keep the &quot;branded&quot; SFX button and continue to call the resource SFX.  The Library User Education Team was consulted about education issues and their conclusion was to incorporate SFX instruction into already existing library instruction sessions.  An Executive Summary was produced and paired with an SFX FAQ to inform and instruct our community. Response: Immediate! Betsy enabled at 9:01 AM on Monday and we had an email by the next morning – a faculty request for a new subscription!  Then a bug report, then a love letter, more love letters, then more subscription requests...But mostly people just started USING it and have NEVER LOOKED BACK ...
  12. 12. Working with SFX: The FAQs of Life <ul><li>How hard is it to get the system up and running? </li></ul><ul><li>What do you still do after the system is functional? </li></ul><ul><li>How long does it take and how many staff are involved? </li></ul><ul><li>How hard is it and what skills does it take? </li></ul><ul><li>How do users like it and what do the use statistics look like? </li></ul>Not very hard at all. Organizing your own collections data is the most time consuming aspect of the setup. Regular monthly updates, weekly knowledgebase (content data) updates, and daily troubleshooting. Frequent updates due to your changing library subscriptions. At Caltech, we only have two staff members who are regularly involved in updating the database. It’s not brain surgery – most librarians and programmers can get it up, running, and regularly maintained. Our users love it – They have difficulty remembering the “dark days” of finding fulltext by their wits and wiles.
  13. 13. How do your library users feel? Your patron now…                                                                                                                                                                    Confused Angry Afraid Frustrated The Various States of Library Research Clueless Interested Astonished Happy Ecstatic Your patron on…

  39. 40. <ul><li>Link Resolvers </li></ul><ul><li>What To Look For </li></ul>Resource Integration Through OpenURL Linking Endeavor Information Systems, Inc.
  40. 41. <ul><li>But first of all, the Good News… </li></ul><ul><ul><li>There are a lot of choices </li></ul></ul><ul><ul><li>There are at least 10 commercially available link resolvers available on the market today </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  41. 42. <ul><li>So, with all of the choices - what should you look for? </li></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  42. 43. <ul><li>Well, I have 9 Minutes… </li></ul><ul><li>To talk about 9 Things </li></ul><ul><li>To Look For </li></ul><ul><li>& </li></ul><ul><li>Ask About </li></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  43. 44. <ul><li>Is it OpenURL-compliant? </li></ul><ul><ul><li>A link resolver HAS TO BE OpenURL-compliant or it will not work with the large and ever-increasing number of databases and systems that can send OpenURLs. </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  44. 45. <ul><li>Can it be purchased as a stand-alone system or subscribed to as a stand-alone service? </li></ul><ul><ul><li>It can be nice and it can be convenient to purchase a link resolver as part of a larger package, but you shouldn’t HAVE TO. </li></ul></ul><ul><ul><li>Link resolvers, like all digital library components, should be interchangeable and interoperable with the products of other vendors. </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  45. 46. <ul><li>Is the link resolver available as a locally run system AND as a Subscription Service? </li></ul><ul><li>Subscription Services offer the advantages of: </li></ul><ul><ul><li>Not having to purchase or re-purpose hardware </li></ul></ul><ul><ul><li>Not having to install and upgrade software </li></ul></ul><ul><ul><li>Not needing IT staff to install and maintain the service </li></ul></ul><ul><ul><li>Ability to “enter” and “exit” subscription service agreements without worrying about investments in hardware and IT staff time that locally run systems require </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  46. 47. <ul><li>If interested in the Subscription Service model, ask about the hosting site. </li></ul><ul><ul><li>Is it a professional hosting site? </li></ul></ul><ul><ul><li>Does it have a good networking infrastructure and redundant connectivity to the Internet? </li></ul></ul><ul><ul><li>Does it have 24x7 monitoring every day of the year? </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  47. 48. <ul><li>Ask about the technologies that are used. </li></ul><ul><ul><li>Any Subscription Service should utilize well-known commercially available components because this enhances support levels. </li></ul></ul><ul><ul><li>Locally run systems should use stable, portable components that can run on multiple operating systems. </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  48. 49. <ul><li>How many journals can the link resolver link to? At how many sites? How many targets? </li></ul><ul><ul><li>There are 10’s of thousands of journals that are available in electronic form </li></ul></ul><ul><ul><li>There are 10’s of hundreds of web sites and databases that host these journals </li></ul></ul><ul><ul><li>Many journals are available at multiple web sites and databases. How many different copies can the link resolver link to? </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  49. 50. <ul><li>Is the user interface customizable? How customizable? </li></ul><ul><ul><li>Customization is important because the library knows its users better than a vendor. </li></ul></ul><ul><ul><li>More importantly, the library should be able to “brand” the interface so that users know that this is a “library service”. </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  50. 51. <ul><li>The “INVOKE” feature - Can the link resolver take the user directly to full-text without having to go through a link menu? </li></ul><ul><ul><li>Many users just want the darn journal. This may or may not describe your users, but you want the option of using this feature if you need it. </li></ul></ul>Link Resolvers – What To Look For Endeavor Information Systems, Inc.
  51. 52. <ul><li>Last, but not least – PRICE </li></ul><ul><ul><li>Today’s offerings run the gamut from really expensive to really inexpensive. </li></ul></ul><ul><ul><li>They offer different feature sets, but they ALL link to electronic journals. </li></ul></ul><ul><ul><li>Subscription Service offerings give institutions the option of “getting in” and “getting out” of link resolvers without having to worry about investments in hardware and software installations. </li></ul></ul>Endeavor Information Systems, Inc.
