You only have to print them. Laminate to make them dew-proof and bind them.

I've recently been using the Triatlas charts and they are very good.  I've been using the 'B' charts for the most part, choosing a target area of the sky and zooming to about three different levels of detail.  At each level I print the view and have them with me at the eyepiece.  This has worked very well in finding and identifing faint galaxies.  Stars are plotted to 11th magnitude so star hopping is much easier. 

One word of warning; the pdf files are huge (40Mb+) and each set of charts is broken down into a number of files.  The 'C' charts have more than 500 pages.
