Shelving Habits

The other day I was going to re-organise my bookshelf.  But when I went to start I got stuck.  I didn't know how I was going to re-sort it.

And it got me wondering how does everyone else organise their bookshelf? Do you go by colour? Alphabetical order? Hardcovers and paperbacks?  Size? Genre? Favourites?

At the moment my main shelf is sort by genre - YA paranormal, YA contemp and Adult Fiction.  In no specific order.  Then my to-be-read shelf is sorted by colour of the book so it looks pretty.  But I really feel I need better organisation.

So I would love to hear how you stack your shelf? 

What works for you? 

Do you ever change it around?

Rating Scale - Stay or Go?

I been think a lot about rating books and changing my rating scale.  Is it really fair to give a book a mark out of 5? Should the rating scale be broken down into categories (eg plot, characters, romance, writing style etc)? Should I get rid of it all together? 

When I read other people's reviews ratings only play a small part in whether I decide to read the book unless it is a low number.  I read a lot of high rated reviews so it all goes down to the content in the person review.  I think there is a big different between 4 and 5 and the rating in between.  And of course there is the books that you want to rate a 100 out of 5, you know those kind of books you would save if your house is on fire. 

So I am asking for your input.  Do you prefer reviews with a rating scale?  Would you like rating scales broken down into categories?  What do you do with your reviews?  I would love to hear your thoughts.
