It helps much to understand the character's etymologies and to that end I'm using this online database. Problem is, I like studying outdoors where no internet is available, hence the downloadable database I'm looking for.

It doesn't have to include explanations in English, just how characters are decomposed and what variations are used (like heart is written in some characters like 忄as in 忻 instead of using the full radical 心)

Or if somebody knows how to download the whole set of images of the webpage I linked maintaining it's structure...

The database I linked is also available as a book (Chinese Characters: A Genealogy and Dictionary, English and Mandarin Chinese Edition) but is so poorly printed characters are sometimes extremely difficult to read.
