We wrote it because there are many different ways to get a CD +or DVD image, and several things that can go wrong. + + +GIVE THEM AWAY! * + +Project Gutenberg urges everyone who can to download and make copies +of their CD and DVD images. Give them away! If you decide to try to +sell them, first read the trademark license at +http://gutenberg.net/license . If you want a CD or DVD but don't have +a burner or can't download so much data, see +http://gutenberg.net/cdproject where options for getting one freely or +at low cost are listed. + + +WHAT'S AN ISO? + +First, you should know what a ISO image file is. This is a special +file that represents the contents of an entire CD or DVD. Project +Gutenberg uses ISOs to distribute entire sets of Project Gutenberg +eBooks, usually with some sort of index file and a copy of +GUTINDEX.ALL (our title listing). All of the books on the CD or DVD +are available individually via the Web pages at http://gutenberg.net + +Computers with CD or DVD burners usually come with some software to +copy the ISO to a CD or DVD that you can then use in any CD or DVD +burner. Some software even allows you to look at the contents of the +ISO file without burning it to disc first. Project Gutenberg does not +try to maintain lists of software, but there are many such lists on +the Web. You can always email Project Gutenberg for help, if you are +stuck. + + +DEALING WITH LARGE FILES + +ISO files can be quite large, which can create some problems. ** If you +have a high speed network connection (at least cable modem or DSL +speed), you can try downloading an entire ISO file all at once. The +problem is that if any data get corrupted during the download +(something that seems to happen a lot on cable modems and DSL lines), +the ISO might not work at all. + +- To make it easier to make sure your download is correct, you can get +the ISO in smaller chunks, and use checksums to verify the integrity +of the files. We supply md5sums, and sometimes other checksums. +If you don't have an md5sum command, use your favorite search +engine to find one (no, Microsoft does not seem to make any standard +checksum programs available with its Windows operating systems). + +For chunking, we often provide a "-parts" subdirectory where the file +might be divided into many chunks. These files were created with the +Linux command + + split --bytes=15000000 --suffix-length=4 pgdvd.iso pgdvd.iso. + +Any Windows or Unix/Linux/BSD computer (including Mac OS X or later) +can reassemble parts using the Unix "cat" command or the Windows "copy +/b" command. Sample commands follow. + +For both, first "cd" to get to the directory where your "parts" files +were downloaded to. Then: + +To join them together on a Unix or Linux system, including Mac OS X +or later, simply: + cat pgdvd.iso.???? > pgdvd.iso + +then, to check integrity, + md5sum pgdvd.iso + +On Windows, this command should work (first get a command shell, +i.e., by "Start / Run / command", and cd to the right directory): + copy /b pgdvd.iso.* pgdvd.iso + +(Make sure that all of the iso files are in one directory.) + +Checking file integrity on a Windows/DOS system requires the use of a +third-party application. Searching the internet, and in particular +various software download sites, will give you several options for +an MD5sum program. + +59d8a193874349181122ff52e2e3e114 is the correct sum. + +See pgdvd.iso.md5 for the MD5 sums for individual files. + +- The WinRAR program (for Windows computers) can be used to reassemble +.rar files, when available. + +- The Jigdo program can be used to download and assemble files based +on instructions in a .jigdo file, when available. + +- We are also encouraging BitTorrents. Visit the CD project page +for current BitTorrent links. + + +FOR MORE INFORMATION + +See the CD project page for further information, including the +possibility of using peer to peer transfer, BitTorrent, and other +options to get the DVD and CD images: + http://gutenberg.net/cdproject + +The Project Gutenberg contacts page at gutenberg.net includes +email addresses for help. + + THANKS for your interest in these CD and DVD images! We hope + you enjoy them, and consider redistributing them. + + +NOTES + +* International Copyright + +The Project Gutenberg Literary Archive Foundation (PGLAF) is committed +to complying with copyright laws. PGLAF has not verified that all the +eBook files on these discs meet the copyright laws in countries +outside of the United States. PGLAF recommends that you verify this +before using these files and requests that you advise us of any +problems by email to copyright AT pglaf.org + +** A note on CD and DVD disc capacity. It turns out that disk drive +manufacturers (including the people who make CD and DVD burners and +blank discs) measure disk space differently than the rest of the +computer world. To them, 1MB, which is 1 megabyte, is 1,000,000 +bytes. For the rest of the computer world, 1MB is 1,046,576 bytes. +We mention this because people might read their DVD disc package and +expect it to hold 4.7GB, but be surprised to find it can only hold +about 4.37GB as the rest of the world measures space. |
