Ahhh Bookcases, the  bain of my life right now. I'm in desperate need of another, only my  house is so tiny I don't know where I would put it. I have seriously  considered getting rid of essential pieces of furniture but I'm not sure  how well that would go down with the rest of the household. 
This  is my 'big' bookcase which I squeezed into the corner of the living  room, shoving the couch along as far as I could to get it in. This one  contains mainly YA books, though there are a few adult ones tucked in  there too. The pile to the side is my review book pile, which was under  control not so long ago (eek) Here's a closer look.
I  don't have a set system really for books, other than keeping  series/authors together and keeping Hardbacks and paperbacks separate.  There's a mix of read and to be reads here, I don't keep them separate  otherwise I'd have parts of series here and different authors there and  that would bug me. One thing I do do when organising my books is try and  colour co-ordinate. It's not working so well now I had to turn the  paperbacks on their sides to fit more on though. 
This  is also in my living room, although it isn't strictly a book shelf.  Well, it's not a book shelf at all actually! There was a hatch there to  the kitchen once upon a time which was replaced with this little unit  before I moved in. The shelves are only thin and only half the book sits  on it and if the books aren't packed tight from edge to edge they fall  off, so it's not exactly practical but it has to do right now. I put big  series books on here. Notice the top shelf is empty...I did try to fill  it but ended up under a shower of books *sigh*
This  nifty little bookcase sits in my hall and contains all my pink and  girly chicklit books! What's great about this one is that it's really  deeps, so the books are all double stacked . It's small but holds a LOT!  Very pretty this one!
So  this isn't actually MY bookcase, it's my six year old daughters, but I  think it may be my favourite in the house. There's so much magic packed  onto those shelves! She's always loved stories and won't part with her  picture books, but she's also a great little reader herself and has  recently started to read her own little novels all by herself. I love  getting her books I remember loving as a child (a couple of them are  from when I was a child) and she's got Harry potter there for when she's  ready, she's already a huge fan.
I  do have one last book shelf area, tucked away in the cupboard under the  stairs which mainly has Adult books, Classics, Text books, Cookery  books and Non Fiction. But this cupboard is also the dumping ground for  hundreds of pairs of shoes, coats, toys, hoover, ironing board, ironing  pile...etc and NO-ONE is seeing that mess! I'm going to be out of space  soon though and desperately wish I had a room just for books *that would  be awesome* because boxing up/getting rid makes me sad. In the meantime  though, do I really need two sofas in the living room......?

You have so many great books! :)
Thank you for sharing! x
I love having a peek at other people's bookcases :)
Your shelves look so neat and pretty! I've no idea how you keep them so organised.
I constantly consider getting rid of furniture to make room for books, too. I think we have a serious problem :p
I love that one shelf with all the books with black covers on them. That looks so awesome. Oh! And a totally full bookcase with a stack of books piled next to it? Guilty as charged.
Thanks for sharing.
Great shelves, thanks for sharing!
I love your little girls book case too, so bright!
