I'm having the hardest time finding member reviews of book. 

I've read the help section here and there should be "reviews" under the search area on the page. Nope.

I click on the number of reviews. Nothing.

I click on More Details when I mouse over a book in a list. Nothing.

I can't find reviews for any of the books I've looked at today.

Is this because some people review books but don't add text, just rate it with a number?

Most don't want to write reviews.  Others write piles of them.  I tend to hit the "Buy from Amazon" button to see what reviews are there.

For a book to be put on your BIR list, you have to rate it, and that's where most stop.

Another good place to look for reviews is Goodreads and LibrayThing. 

I tend to be a non-reviewer myself.  I wrote a few when I first joined, but not really any since.

I've noticed on several books that most of the reviews are really old, from 2005 etc. It doesn't seem like too many are doing them anymore.

I try to write a few especially if there are no others.  I'm always pleading for more reviews on non-fiction books.

 This was discussed a few months ago as people were complaining about those who review a book by saying "good read" or " best in the series" with little or no other evaluative input.   But what was obvious is that few members  "review" any books they've read and almost noone, except me it seems, uses the tags. I love tags and have reviewed many of the books I've read since joining PBS one year ago, but if the book has been out several years, I will often read the other reviews and if they almost duplicate what I'd say, I don't review it.  I also rate a lot of the reviews I read because I believe in being an "active" member of anything I join.

I do what you do, Jeanne.  I rate the reviews, too.  Most of the books I've recently read all have reviews.  Maybe I should choose my next book by seeing which don't have reviews.

I love reviewing the books I read, I guess because I am opinionated

I even write them for books that have a lot of reviews.  And I love when people give my reviews positive ratings.  It makes my day that I can help someone to decide whether or not they will spend time reading a book I reviewed.

I have found many great books here by the reviews I read.  Especially the featured review on the homepage.

What Ruth said.  If I'm researching a book at PBS without reviews, I pop on over to Amazon.

I'm pretty much a non-reviewer too. But, occasionally I hit a book that just totally intregues me when I read it and then I write a review when I post it. But, the post above that mentions most posts being older than 2005 is correct. Up until then, we got the impression that we couldn't post a book without a review, AND since we couldn't see if there was a description, nor could we add one anywhere but in the review, that's what happened a lot.
