I used to go alphabetical order but found a much more challenging and fun way (especially if you have a LOT of DVDs) to place your movies. I use the common thread method now. It is like a real challenging puzzle to find something that movie A has in common with movie B and place them as such. I use Genre, Actors, Directors, studio or date as criteria. For example Shawshank Redemption is next to Green Mile which is next to Cast Away which is next to Forrest Gump etc. etc. Try doing that for a whole collection! I have a little over 200 so I can't imagine what it would be like for way over that! But it was a lot of fun to figure all of these out!
