My dilemma about back issues of Wargames Illustrated and Miniature Wargames has now been solved. I've bought the back issues on CD. An excellent purchase, and in some way might be the way to go with storage. One CD has 25 issues (2 years and 1 month worth of issues), where as 25 Issues equals a lot of book shelf space "lost". My White Dwarf Collection spans two whole shelves, with a start on a third on it's way.
I do love looking through the back issues. I get a lot of inspiration for terrain modelling and period interest by just flipping the pages. Tactile responses to physical properties cannot be underestimated.
