You are welcome to download and use these documents for your own personal use, but not to upload them to another website etc.
I would recommend that you download the pdfs and view them with Adobe Acrobat as opposed to trying to view them with your web browser, in particular the Line Transmission Equipment as it has bookmarks to make navigation easier. All the files are computer searchable.
