Last week, I had the privilege of attending Lincoln Trails Symposium on the The Future of the Integrated Library System. One of the many highlights of the conference for me was Karen Schneider’s talk on the state of the OPAC in late 2007. As most of you probably know, Karen Schneider — author of the blog “Free Range Librarian” — has been leading the charge to a more user-centric OPAC for several years now. So, I confess to more than a twinge of pride when Karen described Koha as a robust, enterprise ILS (For more on Karen’s views on Koha, Evergreen, and open-source software check out her recent TechSource article on Enterprise Open Source.)
During her presentation, Karen got specific about her vision for the Next Generation OPAC, offering up a fantastic checklist for ILS companies to consider. Of course, I immediately began making a mental survey of how Koha ZOOM stacked up, and decided that list was quite a bit more useful outside of my own head. So, here it goes…
Spellcheck
Karen notes that usability studies show that mis-spelled words cause up to 10% of user failure (The example Karen gave was that a search on “cheesee” won’t retrieve ‘cheese’ related items in many ILS systems).
Firing up my browser, I point it at my local library OPAC here in Athens, Ohio (which runs Koha, of course). Koha ZOOM currently uses auto-correction without feedback, and as I moved from ‘macey gray’ to ‘loyd alexander’ to ‘massachussetts’, I have to say ZOOM handles this really well, though it would be nice to give the user some feedback when terms are auto corrected.
ZOOM passes the ‘cheesee’ test. It also passes the “Salmon Rushdie” test — one of my all -time favorite authors whose spelling proximity to the fish often relegate him to OPAC obscurity in less competent ILSs. Mispelling Salman (”salmon rushdie”) in the Athens County’s OPAC retrieves all 13 books written by the author in the county’s collection–the same number retrieved by a search on the correct spelling (”salman rushdie”).
Compare this to TLC Aquabrowser’s handling of the search query “salmon rushdie” which retrieves only 2 of the rushdie books in the Queen’s Library catalog. http://aqua.queenslibrary.org/ (The correct spelling: “salman rushdie” retrieves 103 results) No offense to the Queen’s Library who have a website design that makes me drool every time I happen upon it!
Auto-correction with feedback (as recommended by Karen Schneider) is definitely compelling.
Relevance ranking
Relevance ranking is perhaps what Koha ZOOM does best. My favorite search to illustrate ZOOM’s stellar relevance ranking is the term ‘it’. As a single word title and stopword at that, I’ve encountered many an ‘enterprise ILS’ that couldn’t find the obvious: “It” by Stephen King.
Note: ZOOM queries on other stopwords like “No” and “The” works too. There is a CD collection of Children’s rock music entitled ‘No!’ and a CD ‘The’ by Macy Gray. Both CDs come up first, just as they oughta.
One reason ZOOM’s relevance ranking is so dead on is that LibLime worked closely with Athens County public librarians to make sure ‘relevance’ worked exactly as they expected. They made a list of all their tough searches, and LibLime made sure ZOOM’s relevance ranking lived up to those expectations.
Same page availability
Check. ZOOM does it and most LibLime clients have chosen for their OPAC to display availability on the results page. You can even limit by availability, and ZOOM’s availability index is updated in real time as circulation happens, so it’s always up to date–no periodic batch process to wait for.
Recommendations (”You might like…”)
The short answer: not yet. This is something I love about Netflix and Karen is right that this is where ILSs need to head. Carl Grant of CARE Affiliates noted in his presentation that one of the issues holding ILS companies back from offering personalized recommendations is that libraries are often reluctant to track ‘borrower history’ for fear of violating privacy issues. He is also correct in pointing out that tracking such history is exactly how commercial sites like Amazon.com manages to offer such relevant recommendations. He goes on to argue that if Amazon.com is any indication of where users fall in the privacy/web 2.0 debate, it seems that the decision has already been made. (i.e., Users prefer good recommendations over privacy).
Based on my personal experience working in a public library for over 7 years, I have had ALOT more users get mad at the library for NOT tracking borrower history because they want to know if they’ve already read a book, or what that book was that they checked out last month with the blue cover
An easy compromise: let users ‘opt in’ or ‘opt out’ to borrower history by logging into their account online. Since Koha users already decide whether to track borrower history based on the library’s policy on privacy (Koha supports both options), letting opt-in/opt-out on a individual user basis should be on the development horizon.
Faceted searching
ZOOM’s got it. I especially love ZOOM’s ’series’ facet which allows users to quickly find out what ’series’ are associated with a prolific writer like Nora Roberts, and then locate all the books in that series with one click. (I myself am not looking for Nora Roberts books
but have helped scores of patrons who were.)
Editions
Koha ZOOM is the first ILS OPAC to offer editions through xISBN apart from OCLC’s Worldcat. Editions support isn’t at the top of every users’ list, but it is very useful for students who frequently need a specific edition of a classic like “Hamlet”. Our developers did a blog post on the Editions feature recently.
Working lists (keeps track of what you’ve clicked on)
This is a fantastic idea. ZOOM doesn’t have this (yet), but does offer “book bag” and “virtual shelves” features for creating lists, emailing them and sharing them with others.
Reviews and ratings
ZOOM has integrated reviews/ratings, as well as enhanced content (jacket covers, extra metadata, etc.). Many libraries still don’t know that there is a free alternative to the significant money they are paying for enhanced content. Meanwhile, Amazon.com offers free book images, reviews and ratings through their web services program, in exchange for a single link back to Amazon’s website. We actually did a blog post on this a while back as well.
Persistent links
Natively a web application, deep linking has been part of Koha from day 1. There are persistent links for all the pages on ZOOM’s OPAC, and even some shortcuts like isbn/ and bib/.
In summary: Koha stacks up pretty well. It’s a testament to the open-source model; the users really DO know what they’re doing, and when they can steer development, you end up with software that is on the cutting-edge in terms of both features and functionality. Of course, we’re not done yet
