Pastor Russell's Sermons is a huge volume of nearly 1000 pages! This and many other items can be viewed from:
www.heraldmag.org/olb/Russell.htm
You can download the entire file or view online. If you choose the latter you must use Adobe Acrobat Reader. Most PC's have this software built in, if not you should be prompted to download it.
The Time Is At Hand (of which there were many versions in print at one time) can be accessed from the following URL:
www.agsconsulting.com/start.htm
Click "Harvest Truth Database (HTDB) and choose Time is at Hand. This site contains 50,000 pages of Russell's writings.
Both sites are connected with some of the Bible Student movements that claim to be the true followers of Pastor Russell's original teachings.
The book "Jehovah's Witnesses - Proclaimers of God's Kingdom" whilst being a monumental work does not to my knowledge contain any specific quotes from any of the above works of Pastor Russell.
If you require any material from Proclaimers then please state your requirements on this thread and I'll extract them from the WT-CDROM.
