Just an avid reader. Mostly SF/Fantasy, some hobbies, paranormal, urban fantasy and lighter, fluffier things.
I have no clue what the ratings scale on booklikes is (I asked). I realize most sites use a version of the amazon ratings but the bulk of my reviews came over from goodreads which are always one star less than amazon. In my case, since goodreads did not do half stars, I did wind up rounding up a lot (for some reason I had a lot of books between "like" and "really like" which on goodreads was a ★★★½☆).
So here is what I've come up with for my own use:
★★★★★ = All Time Favorite
★★★★½ = Extraordinary Book. Really Loved It.
★★★★☆ = Loved It.
★★★½☆ = Really Liked.
★★★☆☆ = Liked.
★★½☆☆ = Liked parts; parts only okay. Would read more by author.
★★☆☆☆ = Meh. Okay.
★½☆☆☆ = Disliked but kept me reading in hopes would get better.
★☆☆☆☆ = Loathed It. Possibly DNF and a torturous read.
½☆☆☆☆ = So vile was a DNF or should have been. An "uploaded" word spew or collection that should not be dignified by calling itself a "published book." Author should take remedial classes for language written in until basic concepts like using sentences sink in. Is author even old enough to sign a publishing contract or do they need a legal guardian to sign for them? Cannot imagine anyone liking.
The Reading Room, I did find out, does use the amazon style scale where 3 stars = okay (although they avoid "hate it"). Their email to me said:
"Thank you for your enquiry. Our rating system works as follows:
5 stars: A must read
4 stars: I loved it
3 stars: It was okay
2 stars: Didn't like it
1 star: Don't bother "
Booklikes via email answered m that they have no suggested rating scale.
Other booklikers tell me that the rating that shows on a book's page here is just the average rating from whatever bookseller you sourced the book from. If that's true, sounds rally confusing because the same isbn from mainstream publishers will be found on an awful lot of bookseller sites. And that's no help for more than 5,000 books I sourced from my own *.csv file.
