Here's the home page screen:
The "Books" link is below the larger word "Family" on the screen above.
The "Family History Books" page has a search field (and a link for "Advanced Search" plus a description of the collection:
The description says:
I entered the term "seaver" in the search field on the screen above, and clicked on "Search"
There were 713 matches for my search term. In the left sidebar, under the term "Refine My Results," there are links for Books (484), Other (184), and Periodicals/Serials (45).
I clicked on the title of the first title, and saw the first page of the book selected (I scrolled down to see the title):
There is a menu line that has icons for save the file, printing the file, zooming, advancing pages, etc. On the right, there is a list of Bookmarks for each page.
I was curious about the Other and Periodicals/Serials collections noted, and think that they include both unpublished manuscripts and printed town reports, but have not categorized or checked all of them.
This particular book is about one line of Seaver families in Massachusetts. I had not read it before, but it has content that is of interest to me as a "collector of Seaver people."
The lesson learned here is that the "Books" collection on FamilySearch has over 40,000 tomes, and that they are well worth looking through. My sense is that there are many works ion this collection that are not available on other online Book archives. For instance, the Seaver book above was published in 1996.

Update: Just before I was going to publish this, I had a BSOD event (that's Blue Screen of Death") that is the first one I've had on this desktop computer. I was paging through the Seaver book above and have no clue what happened! That's why you may have read one or two paragraphs of this post.
