Hathi Trust eBooks
/Hathi Trust Digital Library includes quite a few eBooks. The links to eBooks in this collection will bring a page that provides catalog information about the book. If the eBook is multiple volumes, they will generally all be listed in the ‘Viewability’ section. The ones with a ‘full view’ link are the whole book.
The view shown after clicking on ‘full view’ is usually the two page one unless the last time the viewer was used, another view was selected. I prefer the two page mode most of the time although I do look at the thumbnails if the book has a lot of text. Use the arrow buttons on the screen or the arrow keys on your keyboard to turn pages.
