In iBooks, go to List view. Click on a title; wait a second, then click on the Title, Author, Category or Collection. It will become highlighted, and you can change the contents of these fields.
It’s tricky to get the timing right. If the second click is too soon, it will be interpreted as a double-click, and either open the book or begin downloading it if it’s in the cloud. Wait too long, and it doesn’t work. You’ll have to figure out how to get it right.
Once one field is selected, you can press the Tab key to go to the next field.
If you can edit metadata, then why doesn’t Apple make it easier, offering an Info window, as in iTunes?
When Apple introduced the iBooks app, and moved ebooks from iTunes, it introduced an annoying constraint. You could no longer edit the metadata of your ebooks. You can’t change the author’s name – which you might want to do to display authors in last name, first name order. You can’t change titles, which you might want to shorten. You can’t change “categories” – or genres – which are often different from what you use to organize your books.
It’s actually ridiculous that Apple doesn’t let you do this. Since your ebooks are more-or-less hidden, you can’t even easily take them out of iBooks and tag them with other apps.
Apple lets you change almost any tags for other media files in iTunes; only books have these limits. There’s no logic to this at all, unless it has to do with the fact that some books can stay in the cloud (see above; two books have cloud icons on their corners), and changed tags could confuse things. Unlike in iTunes, where you can turn off “iTunes in the cloud,” you can’t deactivate this in iBooks.
Those who have a lot of ebooks, and who don’t buy them from Apple, know that they can tag their books in Calibre before adding them to iBooks. But it shouldn’t be this way; tagging is a basic operation that should be available for all media files.
This got me thinking. Could Apple be planning to bring ebooks back into iTunes? There was a logic to splitting them out, and releasing the iBooks app. This app serves three purposes:
You can manage ebooks with it
You can read ebooks with it
And you can buy ebooks from the iBooks Store
But the iBooks app is the only part of the iTunes Store that isn’t in iTunes. And you can still purchase ebooks from iTunes; they just download into iBooks afterwards. It is a bit confusing having two storefronts, and two different interfaces. Add to that the fact that iTunes still manages your ebook syncing. So what’s the point of having another app?
I know, you’re probably thinking, “But they should dismantle iTunes; it’s too bloated!” It’s a valid point, but one which I feel to be incorrect for many reasons. The main one is that, as long as you’re syncing all you media content with one app, it makes things more confusing to have multiple apps to manage that content.
In any case, you can add PDFs to iTunes now, and you have been for a very long time. If you add a PDF to your iTunes library, say by dragging it to a playlist, it gets added with the Media Kind of Music. This is because the assumption is that you’ll be adding digital booklets that go with albums you’ve downloaded.
If you change the Media Kind to Book, however, you see different fields in the Details tab of the Info window.
These fields are appropriate for a book, suggesting that Apple has planned to either let you store ebooks in iTunes, or shift your books from the iBooks app.
Note that if you change the Media Kind of a file to Book, you won’t be able to find it in your iTunes library. There is no Books library (well, there is, but it’s hidden; see below), and, unless you put it in a playlist, you won’t be able to see it. It won’t show up in searches either. I put the two books I used for the screenshots above in my iTunes library, setting the second one to the Media Kind of Book, and here’s what I see when I search for the author’s (my) name:
If you right-click a book, and choose Show in Playlist, you’ll see that the Books playlist is listed:
Select it, and iTunes jumps to the Book List in the Audiobooks library:
There’s no direct access to this Book List from the Audiobooks library. But if you click the View Options menu, you’ll see options that fit with a Books library:
Perhaps Apple has found that not enough people buy ebooks, or that many still buy from iTunes and not the iBooks app. Perhaps they want to shore up ebook sales, and make media management more coherent.
For now, this is all speculation. But there’s no reason to have the Book Media Kind, or to have windows that show fields for books, and a hidden Books library, unless they’re going to serve a purpose. This code is certainly needed for people not running Yosemite or Mavericks, which don’t have the iBooks app, since iTunes still manages ebooks on earlier versions of OS X. But since there is no iBooks app for Windows, it could be more logical to roll ebook management back into iTunes, to unify the app across platforms and OS versions.
