"what must be about 5 hours worth of reading."

In that case for you then, consider that most people would prefer NOT to have to hang on line for that 5 hours, but read it offline (off their own hard drive) at their own leisure. Also people like me on dialup still pay per time connected, as well as per amount of data delivered.

And if you are going to get them to download it, it would be better appreciated if you were to compress it with a 'zip utility', which would make it a much smaller file and thus faster to download - this would then allow you have have even more available.

It would also then still be better to split it up into several smaller files, as each would be quicker to download for dialup users. Dialup users could also then arrange to collect it via a 'background downloader' whilst doing other things.
