I cannot add a book that has a page

I need help. I've been trying to add the anthology Ten First Dates to my books and when I search to add it to my books there is not results. If I search the book and add it from the book page (https://www.librarything.com/work/28508074) they system also says "could not find any results" I don't know what to do.

>1 bookjunkie57: It was a limited edition ebook anthology that doesn't exist in available sources anymore. You have to add it manually.

In fact, none of the entries shows a source. You find manual entry below your list of sources on the Add Books page.

>4 MarthaJeanne: Yes some do. Several show Amazon as the source, which is logical since it was available as a Kindle edition before it went out of print. e.g.

>3 Taliesien: Thank you. I considered that but did not want to load the system with duplicates.

>4 MarthaJeanne: Thank you

The system is designed to combine various entries into works. If your copy doesn't auto combine, that is also easy to do manually. This is the case both if you enter manually or from a source.

>6 bookjunkie57: It won’t create a permanent duplicate - if it matches, it will auto-combine and your book will appear as part of the work immediately. If it does not, we can combine it manually.

Even if you add it via a source, it may not autocombine. So there is no real difference between adding manually or via a source in that regard.
