[76.1] Single Book Page: similar textbooks component

[bdolor]

Is your feature request related to a problem? Please describe.
On an individual book page, it is desirable to have similar textbooks displayed.

Describe the solution you'd like
A clear definition of 'similar'

Describe alternatives you've considered
It could be that it's simply grabbing from the broader category of the book on display, or more specifically, the secondary subject area, or it could be text-mined for a measurement of similarity via what has been started in https://github.com/bccampus/opentextbooks/tree/ml

Additional context

As a...faculty member
I would like...to find similar/related textbooks
So that I can...shorten the path to find what it is that I'm looking for

From Lauri:

I suggest that we use the following parameters to define 'similar'.

1. display books from the same sub-category as the main book; books within the same sub-category are defined as 'similar'

2. determine whether

• a maximum number of 'similar' books should be displayed to fit the 'similar books' box OR
• all 'similar' books should be displayed and dynamically rotated through the display box

3. if a definitive number of similar books are to be displayed, then select other parameters to use that will further define similarity between books, e.g., tag each book with:

• keywords that further define its subject area (select 3 to 5 words)
• course level
• type of resource
• program

From Josie:

I like showing books from the same sub-category area. This allows instructors to jump between books without having to navigate back to the search page to click on the next one.

My suggestion would be to display what fits (maybe three or four books, or fewer if that's all that's available in that subcategory) and then if there is more, be able to scroll through them to see all available in that subcategory.
