After I changed the GUID of the separated backside I forgott to make an corresponding change of the recolors. Dharden noticed that and told me that. Now I have fixed it. Thank you!

I made 2 backsides for my child's room recolors and 26 for my office recolors.
You need an Extra-CEP for this. Then you can exchange all backsides.

Because of the hint of dharden , that this CEP conflicts with plasticbox's recolors of the books, I offer those people, who use the books recolors, an additional possibility to change the backsides
Instead of the CEP and the recolors for the backsides, you can download the folders with separate in the name. The you can buy it for 0 §.
I recommend to choose either the CEP or the mesh for the separate backside, not both.

Catalogue Info:
BiblioFile Bookcase: Hobbies//Bookcases//Price: 400 §
or
Backside of the BiblioFile Bookcase: Hobbies//Bookcases//Price: 0 §

I hope you will like it.

Required, but not included:
For this you have to install the extra CEP from http://modthesims.info/download.php?t=600590.

for the hint of the conflict with plasticbox's recolors of the books and for finding a problem with the recolors of the separated backsides, I could fix now.
