Since there are possibly thousands of links there, and you cannot download everything all at once like in a zip file or a torrent, I would recommend that if you want to download this, you do the following:
If you are using Chrome, download an app extension called "Download Master"...
https://chrome.google.com/webstore/detail/download-master/mcceagdollnkjlogmdckgjakjapmkdjf
You can then click on the app extension and it will list all the download links. You can search for just specific links...
For example, if you want to download all WT's from the 1880's, you search with the custom filter "w188" and it will search for all links with the phrase starting with "w188"... w1880, w1881, w1882, etc...
If you want all the books, then the search string in the custom filter is "WatchtowerLibrary/books/"
Please PM me if you have any questions.
The total WT library is around 16GB... it took me days to make sure I had downloaded ALL of it...
The archive.org website also has recorded talks, and many many many things...
For example, to hear the talk, "Times in Which We are Now Interested" by Fred Franz, you can search on their website for:
"which we are now interested AND mediatype:audio"
and it will show up...
The archive.org website has helped me much in many things, you can find just about anything you need to disprove the WT...
Happy searching!!
