I'm with alucarda... and I use the computer for finding/organising - that's one of the things they save people wasting their time on - and as for books, they're self-organising - author, title, series and primary grouping, anything else needed is fine but definitely personal and I'd rather read than be bothered... and I rarely have problems with several terabytes of data...
Time to read, photograph, improve my artwork etc. is far more useful than time wasted on something of no value to me... for those who need it, fine but for the rest of us then "good enough" is "good enough" and we can get on with what we value and find important... each to their own life...
