Sounds too simple, but it really works I can actually find things now. Now I can do a simple VL on, for example, "mystery", and then refine it for ("mystery" and "Italy") or ("Mystery" and "Missing Persons" and "Female Sleuth") or whatever I want.

With simple codes you can concatenate, you can do wonders. Now I never accept publisher tags blindly. It took me months and a lot of regex to purify the tags in my collection, but worth it. They have no discipline, they just stuff anything in-and are often just plain wrong. 300 tags (including local place names, of which I am fond) of no more than two words each-almost all one word-for nearly 30,000 books. I abandoned it for a simple tag list, and I mean simple. You can't imagine how many combinations you need until you start trying to enter them. I tried that a few years ago and drove myself halfway to the booby hatch trying to organize it and keep it up. Yes, you can create a multi-tiered genre column. Man, sounds like you're trying to swallow the whole thing at one gulp! If my questions are too noobish, please do point me in the right direction for further reading. I also noticed some of the published dates when automatically downloading meta data are incorrect by upto a few years.is there a particular source you use for this info? I noticed the cover source can be changed, but can the source for metadata also be changed? Is there a way of marking books as read? Or would I have to create a custom metadata tag and add a column? Maybe even a plug in which sorts titles by Dewey code? (Akin to how I used to manually create folder trees before Calibre). Ideally, I'd like to have two or three tiers of genres under which I can group my titles.


Is there a way of seeing which titles have NOT been categorised as well? So I can then manually add orphan titles to groups? So far, I managed to quickly create virtual libraries for non-fiction by author or series, but does anyone have any ways of creating multi-tiered genres? This would be especially helpful for my non-fiction collection: when I downloaded meta data, each title has multiple tags, so I find it a bit tricky creating VLs with tags. How do you keep it all organised by genre? Do you use virtual libraries, or one of the plugins? Or do you organise it by some other system? Browsing through some of the posts here, I notice there are several of you with mammoth collections all being managed on Calibre. Just started using Calibre to organise my ebooks and am looking for a few tips.
