Yesterday, during Brian Kelly's opening session on Web 2.0 at the CILIP "Fly in the Web: Power to the User" event at Leeds Met, I started to think about ways of our linking library stuff into del.icio.us…
One of the things I've already hacked into the OPAC is the ability for a user to see their lending history — you can see a bit of it at the foot of this screen shot:

So, I decided to play around with the del.icio.us import facility to see if it was possible to export the lending history from the OPAC and then import it.
The first thing I did was to get a version of the lending history in a suitable format (see Netscape Bookmark File Format). You can see my bookmark file at this URL:
http://webcat.hud.ac.uk/history/5/5d/5da5fe138f7cf2…html
(I should point out that my library card gets used for a lot of testing, so I haven't really borrowed everything on there… honest!)
If you look at the HTML source for the page, you'll spot that I've included the tag "hudunilibrary" and (when available) the ISBN for each item. Each item also has a description for the last checked date & time (I'm still not sure if I should include that info?).
Once you've got the bookmark file, you then need to save it to your hard drive and run the import process in del.icio.us:

The only real potential problem is that del.icio.us automatically marks all imported links as "private" — so, if you want to share your lending history, then you need to manually update every link (very tedious!). Anyway, I've shared a few just so you can see the tag in action:
http://del.icio.us/tag/hudunilibrary
The import facility at LibraryThing is able to pick out the ISBNs in the bookmark file, so it's also possible to transfer a subset of the lending history into there:

The Dynix/Horizon OPAC also has a "My List" facility, so I might see if it's possible to hack that to output a suitable bookmark file as well.
I did mean to take a few photos at the CILIP event, but totally forget until Sheila Webber was halfway through her session on blogging — anywhere, you can find a couple of photos here. I think someone may have taken a shot of me during my workshop session, although I'm not really the most photogenic of people!
