are 1-13 only binarys, or are the sources included?
They *all* are binaries. But the packages are included in order of popularity (see the package popularity-contest), so the most used programs are in the first disc, and the rarest on the last. Usually the best aproach is to download the first and second discs, and if you need anything else, download (apt-get) it.
