Delicious Library is an outstanding Mac OS X program for organizing personal book, movie, and CD collections. It's a little pricey at $40, but it's worth the dollars if you own a lot of media and are somewhat obsessive-compulsive. Unfortunately, it doesn't come with a great way to export the data to the web. This page will tell you how to convert your Delicous Library into a MediaWiki table, suitable for use on the Books You're Welcome to Borrow page.
First, you need to download this Perl script: Media:DeliciousExport.pl. (You may need to control-click and say "Save As...".)
Now open up a Terminal. It can be found in /Applications/Utilities. We're going to run this script, which will find your Delicious Library and put the information about books in a nice pretty format. First "cd" into the folder where the script is. If it's on your Desktop, you'll type
cd Desktop
But it could be somewhere else. Anyway, now we're going to try to run it:
perl DeliciousExport.pl
If it can't find a library
You might get an error about not being able to find HTML::Template or something like that. That's OK, it's not too hard to download. Type
perl -MCPAN -e install HTML::Template HTML::Template::XPath
Follow the set-up prompts, if you get them. They're kind of scary, but if you use the defaults you'll be just fine. CPAN, by the way, is the Comprehensive Perl Archive Network, and it makes it really easy to download Perl libraries that do useful things. (It's easy after the initial configuration, anyway.) DeliciousExport.pl is actually a pretty short script. Most of the heavy lifting is done by CPAN libraries.
Once the libraries are finished installing, run it again:
perl DeliciousExport.pl
If it's working properly
It'll ask you for your name, the location and type of your collection, and your Unix ID. This information is used to make the format consistent with the Books You're Welcome to Borrow page. If you want a different format, like plain HTML, you can of course open up the script and poke around. It's a short script, so you should be able to figure out what's going on, even if you don't know Perl.
By default, the script will print to the Terminal window. That's actually not very useful. If you want it to show up in a TextEdit window, from which you can copy it into the web browser, type
perl DeliciousExport.pl | open -f
