The Poser version will be available shortly. If you can't wait then there's an earlier Poser version of this (but only the rows, not the stacks), uploaded to ShareCG about six months ago.

Seven rows and seven stacks of books, with some adjustment sliders to give a bit of variation. Both the rows and the stacks come in 64, 32, 16, 8, 4, 2, and 1 book sizes.

Each book is a mesh of 88 vertices/86 faces, so the 64 book row/stack each contain 5504 faces.

Three different 1024x1024 texture maps (64 books per map) giving 192 different books in total.

3Delight and Iray material presets to apply each of the three texture maps.

I've also included (in the 'Extra Stuff' folder in the ZIP) a GIMP XCF file (and a Photoshop PSD) containing a template and notes for creating your own textures, plus the text and colours for the three included texture maps on separate layers.

The two included DAZ scripts are run as post-loads every time you load a prop or material preset and simply ensure that the 'Texture Row/Column' integer sliders correctly change the tiling offsets on the material.

The 3Dcheapskate* occasionally posts sensible stuff. Usually by accident.
And it usually uses Poser 11, with units set to inches. Except when it's using Poser 6 or PP2014, or when its units are set to PNU.

*also available in ShareCG, DAZ, and HiveWire3D flavours (the DeviantArt and CGBytes flavour have been discontinued).
