We also use these sheets to create a "no list" - a record of any time we have to tell a patron "no" for any reason (to help improve our yes-based policy). Usually, the reasons are "no, we don't have that book/subject," but also things like "no scanner" or "no jumper cables" show up.
Last time we did this, one staff person wrote down, "no juicing books." To me, "juicing" has always meant taking steroids, but in this case I guessed they meant making your own fruit and vegetable juices at home. So, I wanted to fill this hole in our collection by ordering a few juicing books.
My first stop for topics like this - popular topics I want to purchase quickly - is to search Amazon. I always use the Advanced Search so I can limit to new printed books, in this case published after 1/1/13 - there are quite a few.
But I was surprised, as I started to click into titles that looked good, just how many were CreateSpace books. It's not unusual to see them on Amazon of course, but they generally don't make up 80-90% of new books on a topic. But in this case, that was easily the percentage.
I found a few non-self-published books to purchase, but also ordered the CreateSpace title Juicing Recipes From Fitlife.TV Star Drew Canole For Vitality and Health. Our Selection policy specifically mentioned we don't buy self-published books, but in this case it was by far the most highly-reviewed book on the topic, so I figured our patrons would like it too.
With the rise of ebooks, I suspect lots of libraries will have to amend their "no self-pubs" policies, as self-published books - and quality self-published ebooks - become more prevalent. We'll still need to apply some selection criteria, but at the same time, I suppose the risk is lower - hopefully these ebooks will be cheaper, and we won't have to worry about them falling apart quickly.
Regardless, I think I will always consider "juicing" an undesirable activity, so I can't help but do a double-take on a title like Juicing with Kids. Not entirely unlike my perennial favorite bit of irony, Homeschooling for Dummies.
