with regards to the actual source link...i've noticed that if you change the link to the month (or even year) you want you will get it
eg
http://slate.msn.com/ebooks/eBc/eBc-october-2003.htm
http://slate.msn.com/ebooks/eBc/eBc-november-2003.htm
so all you have to do then is iSiloX it (or change the file extention)
