I created a windows store app to view calibre databases. I did this mostly because no one else had gone through the trouble, and for my work I happen to manage a large collection of archival material. Since I prefer writing books away from the internet, arranging web access wouldn't help.
The app is called Calibre Viewer and it just passed certification today, meaning that it's available now. I'll add the link below for anyone who's interested.
What it can do is the following: it can open a Calibre library and display all the documents contained therein. It will display details about any given book (cover, comments, and so on). It allows you to search by title and author. It also displays tags and allows you to search books by tag. Since I don't use tags very much myself, there is a switch in the settings flyout to turn them off and gain some screen real estate. It implements a full screen view, portrait mode, and snapped mode. Double tapping any book will launch that book in whatever viewer you have associated with that filetype.
What it cannot do is edit. This is a viewer that allows you to view, search, and use your collection in metro. Also, at this time, it can handle one library at a time. If there is sufficient interest, I may work towards a more complex version that can handle multiple libraries and maybe allow edits. I'm sure I'll discover other things that may prove helpful.
Moreover, I'm a historian, not a developer. As such, it's very minimalist, but that was rather the point for me (the last time I programmed anything was over a decade ago). If this thing seems useful to you, or if you find a bug of some sort, or you have a suggestion, please don't hesitate to let me know.
It's listed in the store at 99 cents -- in hopes of recouping the stupid developer's license I had to purchase (otherwise I could not even deploy it to my own machine). However, the trial version is 100% identical and has no time limit. I.e. that 99 cents is completely voluntary. There are no ads, because I hate ads with a vengeance.
Here's the link in case anyone's interested:
