Traveling with textbooks So I am finishing my MSc in Europe and it looks like I will be headed to the US for a PhD. Along the way I have collected a small set of textbooks that I find particularly useful. From my experience, most academics have a reasonable number of textbooks in their offices so I cannot be the only one in this situation. These books can be hard to find and are costly to replace. 

However, textbooks are pretty awful to carry around. Even a modest number make any box very heavy. 

So what I am asking is this. Is it worthwhile to transport books around the world? Is there a best way to do it? Since I an impecunious student I am hoping to do this cheaply.
Have you considered using ebooks in situations where they're available and reasonably priced (and don't have Digital Rights Management)?  

A few years ago when I went to Los Angeles for a sabbatical leave, I made it a point to get electronic copies of as many of my frequently used books as possible.  I bought a few, but mostly I was able to work with freely available copies.  This dramatically reduced the number of printed books that I had to take with me.
