Complete information on the download and store on an SD or CF card is available here -

There are versions ranging in size from 500 megs to almost 4 gigs, and you can build your own version up to about 25 gigs if you have the space
The smallest versions are text only, a 900 meg version downloadable has most of the images, and the larger versions have higher resolution images and can either be purchased on dvd for about 20$ or you can build it yourself, though it can take about a week or so of nonstop processing.
I use the 900 meg version from here -

Its the one called TR3_WP_EN_(P)PC_IMG.zip
All of these require TomeRaider to view, and to be honest, this encyclopedia is the only reason I purchased TomeRaider and am very satisfied with it.
