Watch out Delicious Library, you finally have some competition on the way. Koingo Software's upcoming Librarian Pro for Windows and Mac will bring some interesting new features to the media cataloging table. While its standard UI doesn't look quite as flashy as Delicious Library's (though it features a 'Gallery mode' that displays everything by cover art that the company hasn't posted a screenshot for), Librarian Pro allows users to catalog PC hardware and software in addition to books, movies, music and games. In fact, it can scan your hard drive (I assume both Macs and PCs) to automatically catalog your software. Users will be able to create smart collections for organizing their stuff any way they please, and Librarian Pro allows for multiple media databases to help keep different collections separate (say, one for your home stuff and another for your work-related books and software). Speaking of staying organized, Librarian Pro can also display a panel of contacts from Address Book to show you who borrowed what, when and how many.
Another cool new feature takes Amazon integration one step further by allowing you to shop the site from within Librarian Pro, immediately adding anything you purchase to your collection. Fortunately, Librarian Pro works with Amazon Canada, United Kingdom, Japan, German and France, and the database is fully UTF-8 compatible spanning both Mac and Windows systems.
Librarian Pro will be available for download and purchase on September 1st (I have no idea why they announced two days early) for $29.95, with a 15-day trial available to get your feet wet.
[Update: By the way, I forgot one thing: to help facilitate switchers, Librarian Pro can import from Delicious Library, DVDpedia, Bookpedia, CDpedia and Gamepedia.]
