You use the Apple Books app to read or listen to items you download from the Book Store. But like Apple's Photos and iTunes apps, Books is an organizing tool, too. All of your ebooks, audiobooks, and PDFs are automatically organized into various standard collections, such as Audiobooks and Finished. But you can create your own collections that make it easier to keep your virtual bookshelves in order.
How to add a new collection
The Apple Books app includes some default collections. You can add to these as many collections as you want and define them however you like. For example, you can create a collection for a particular author, genre, or topic. And you can put the same book into multiple collections. Here's how:
- Tap the Library tab.
- Tap Collections.
- Scroll to the bottom of the list of collections and tap New Collection.
- Type a name for the collection.
- Tap Done.
How to add books to a collection
Empty collections are no fun. Here's how to populate them.
- Tap the Library tab.
- Tap Edit.
- Tap the book(s) the you want to add to a collection.
- Tap Add to....
- Tap the collection to add the books to.
You can use this same process to add a book that is already in one collection to another collection.
How to reorder or delete collections
Maybe you have a long list of collections and you'd like to put a particular one near the top of the list. Or maybe you want to delete a collection. You can do both in Books.
- Tap Library.
- Tap Collections.
- Tap Edit.
- To move a collection, touch and hold the gripper and drag the collection up or down to its new location.
- To delete a collection, tap the delete button.
- Tap Delete.
- In the sheet that appears, tap Delete.
- Tap Done.
Another way to delete collections? Swipe left on the list of collections before you tap the Edit button.
How to sort books
Books offers a quick way to sort books in your library and within collections. We'll use the library in this example.
- Tap Library.
- Tap Sort.
- Tap a sort preference.
How to sort books manually
Just like being able to organize books on a bookshelf in your office, you can reorder the way your electronic books appear in the Books app—both in your entire library and within collections. Here's how to reorganize your virtual shelves.
- Tap Library.
- Touch and hold any book until it lifts off the screen. A darker shadow will appear behind the book.
- Drag the book to its new location.
How to delete, hide, and unhide books
Most people don't keep every book they've ever read within arm's reach. You probably feel the same way about books you've read on your iPad or iPhone.
We'll explain the steps for clearing out the clutter of finished books using the Library tab, but you can follow the same process within a collection.
Deleting books
- Tap the Library tab.
- Tap Edit.
- Tap the book(s) you want to delete.
- Tap the Delete button.
- Tap Remove Download to delete it from the device.
There's another way to remove books:
- Tap the More button (a series of three dots) under any book
- Tap Remove....
- Tap Remove Download.
Hiding and unhiding books

If you don't want to see the cover image for a book that has been removed from your device, you can hide it. One of the nice new iOS 12 features in Books is that it's now easy to hide selected books.
- Tap Edit.
- Tap the book(s) you want to hide.
- Tap the Delete button.
- Tap Hide Book.
If you want to unhide a book, do this:
- Tap the Reading Now tab.
- Tap the account icon. It's either your picture or your initials and it's located in the upper right-hand corner of the screen.
- Tap Manage Hidden Purchases and enter your Apple ID password if prompted.
- Scroll to find the book you want and tap Unhide to make it visible in your library.

How to re-download deleted books
You've done a great job keeping your virtual bookshelves neat and tidy. You've meticulously organized your collections and gotten rid of books that you've finished. And now you want to go back and re-read a book that you've deleted from your device.
Fortunately, Apple Books makes it easy to do that, whether or not an image of the book's cover remains visible in the app or not. Let me explain.
Redownload a book that is visible in your library
The Books app can continue to show the cover image of a book that you've deleted from your device.
Even though the book has been removed, the small cloud icon underneath the image of the book's cover means that it's among the list of books that you've downloaded from the Book Store...and it can be redownloaded from the Book Store with one tap.
- Tap the Library tab. Alternatively, if the book appears in a collection, you could look for it there.
- Tap the book you want to re-download.
Redownload a book that is not visible in your library
You don't have to allow cover images of deleted books to remain visible in your library. You can easily hide books after you've deleted them from your device. But to redownload a hidden book, you'll need to unhide it first.
- Tap the Reading Now tab.
- Tap the account icon. It's either your picture or your initials and it's located in the upper right-hand corner of the screen.
- Tap Manage Hidden Purchases and enter your Apple ID password if prompted.
- Scroll to find the book you want and tap Unhide to make it visible in your library.
- Tap Account.
- Tap Done.
- Tap the Library tab.
- Tap the newly unhidden book to download it.
How to sync your Books library on iPhone and iPad
If you read books or listen to audiobooks on multiple devices, then you'll appreciate the syncing features of Apple Books when used in conjunction with your iCloud account. Along with your Reading Now collection, bookmarks you place and notes and highlights you create in books will also sync between devices. In addition, you can sync any PDFs stored in Books via iCloud Drive.
To make all this magic happen, you must first allow Books to use iCloud and iCloud Drive.
- Tap Settings.
- Tap your name.
- Tap iCloud.
- Tap the switch to turn on Books.
- Tap the switch to turn on iCloud Drive.
Now, turn on some switches for the Books app.
- Scroll to the top of the list and tap Apple ID.
- Tap Settings.
- Scroll down the list and tap Books.
- Tap the switch to turn on Reading Now.
- Tap the switch to turn on iCloud Drive.
Tapping Update Other Devices will show you any other devices that require an OS update to sync changes to your library.
How to sync your Books library on your Mac
In addition to keeping your Books library, bookmarks, notes, highlights, and PDF files in sync on all your iOS devices, you can get the Mac in on the action, too.
As with syncing your Books library between your iOS devices, setting up syncing on your Mac is a two-step process.
Enable Books on your Mac to use iCloud and iCloud Drive
- From the Apple menu, choose System Preferences.
- Click iCloud.
- Check the box to enable iCloud Drive.
- Click the Options... button for iCloud Drive.
- In the Documents tab, check the box to enable Books.
- Click Done.
Enable sync settings for the Books app
Open the Books app and do the following:
- From the Books menu, choose Preferences.
- Click General.
- Check the box to Sync bookmarks, highlights, and collections across devices.

Kerberos Preferences on Mac OS X 10.4 and 10.5 Documentation |
This web page discusses the edu.mit.Kerberos
(Kerberos configuration)file: what's in it, where it goes, and how to configure it for distribution atyour site.
The information on this page applies to Mac OS X 10.4 and 10.5 only. For links to preferencesdocumentation for other Mac OS versions, go here.
The edu.mit.Kerberos File
The edu.mit.Kerberos
file is where the Kerberos v4 and v5 configuration information isstored on Mac OS X. Formerly the Kerberos Login Library and Kerberos management applicationpreferences were stored in it, but they now have their own preference files: edu.mit.Kerberos.KerberosLogin.plist
and edu.mit.Kerberos.KerberosApp.plist
.
The edu.mit.Kerberos
file stores this information in its datafork, which contains the realm and server configurationinformation (the info that would be found in the krb5.conf
file onUnix). See the Kerberos Configuration File Format section for moreinformation.
On some systems there may up to three configuration files - two edu.mit.Kerberos
filesin the 'system' and 'user' locations, and KfM now acceptsthe standard Unix location and name of /etc/krb5.conf
for the configuration file as well.Some settings in the edu.mit.Kerberos.KerberosLogin.plist
file can override settingsin the edu.mit.Kerberos
as well. See the edu.mit.Kerberos FileLocations section for more information about why this is so.
Setting up a Configuration File Quick Guide
We recommend that you read this entire page. However, if you are in a hurry toget Kerberos for Macintosh up and working:
You need to create an edu.mit.Kerberos
file in the /Library/Preferences
directory which contains the realm and server configuration information for your site, although:
- if your site supports DNS configuration of Kerberos realms, you may not need a configuration file, or at least not a complete one - see the About DNS Configuration section;
- if you upgraded from a previous version of Mac OS X which was using Kerberos successfully, you probably already have a properly configured file and no changes are necessary;
- if you've run the Mac OS X Kerberos Extras installer, you will already have a file in the correct place, but which contains MIT configuration information (which is provided as a guideline);
- if you have a functioning Mac OS 9.x Kerberos installation, you can simply copy the
Kerberos Preferences
file from theKerberos
folder inApplication Support
from your Mac OS 9 volume to the/Library/Preferences
on your Mac OS X volume, and rename it toedu.mit.Kerberos
.
If you do not have an edu.mit.Kerberos
file:
- Launch the Kerberos application (
/System/Library/CoreServices/Kerberos
). - Choose Edit Realms... from the Edit menu.
- Use the edit realms dialog to enter information about your site's realm. See the Kerberos Configuration section for information on what the various fields mean.
Note - while there may also be an edu.mit.Kerberos
file in your/Users/username/Library/Preferences
directory, you should placeyour configuration information in the /Library/Preferences
location. (See edu.mit.Kerberos File Locations for moredetails.)
edu.mit.Kerberos File Locations
Kerberos for Macintosh supports and looks for its configuration file in three locations -two are standard locations and the third for Unix compatibility:
/Library/Preferences/edu.mit.Kerberos
- the standard 'system' location that contains the configuration to be used by all users of the computer,/Users/username/Library/Preferences/edu.mit.Kerberos
- the standard 'user' location containing additional configuration for an individual user,/etc/krb5.conf
- the Unix compatibility location. Any configuration file in this location will also apply to all users of the computer.
The typical case is to have the Kerberos configuration information inthe standard system configuration file, and no user configurationfile or Unix compatibility file.
However there may be circumstances where a user wants to have additionalrealm and server information not shared with other users on the same machine.You can add any additional realm and server configuration information to theuser configuration file, and KfM will meld the two sets of informationtogether. You should avoid duplicate realm entries - if you have the sameentry with different information in different configuration files, the behavior isnot defined and you may get unexpected results.
If the user wants to have additional items in the [libdefaults]
section,it's important to be aware of the order in which KfM reads the configuration files,because in case of conflicting [libdefaults]
entries, the entry readfirst is the one that KfM will use (this is different from the situation with realmentries, which are merged). KfM first reads the configuration file in the user location, then the onein the system location, and finally the Unix compatibility location.
Similarly, if there is a configuration file in the Unix compatibility location,KfM will attempt to meld those the information in it together with any otherconfiguration files present, with behavior as described above.
Having just a user configuration file and no system configuration file is not asupported setup. For instance, getting Kerberos tickets at login time will not workif you only have a user configuration file. The Mac OS X login window will not read the user configuration file.
Note: some settings in the edu.mit.Kerberos.KerberosLogin.plist
, theKerberos Login Library preferences file, can effectively override settings inthe edu.mit.Kerberos
file.These settings can be modified using the Kerberos GUI management application/System/Library/Coreservices/Kerberos
.
How To Create Library Preference For Mac Free
Generally, site settings go in the /Library/Preferences/edu.mit.Kerberos
file, anduser settings will go into ~/Library/Preferences/edu.mit.Kerberos.KerberosLogin.plist
(via changing settings in Kerberos.app). The Kerberos Login preferences exist so that the user can changetheir ticket management preferences without changing those preferences for every user on the machine.One user might always want addressless tickets, but another user might not.
In addition, there are some options which cannot be set with the [libdefaults]
section of the edu.mit.Kerberos
file. For instance, there is no edu.mit.Kerberos
file preference to set the default ticket lifetime - despite config files which claimthere is a 'ticket_lifetime' tag, no code actually looks for it.
Kerberos Configuration Information
A Kerberos configuration is made up of a list of realms and a list of domain->realm mappings.
Each realm entry contains a list of servers and a default domain for the realm. Each type of server has a different purpose. 'kdc' servers are used to obtain tickets. 'admin' servers are used to perform administrator operations, such as running kadmin. At most sites there will only be one admin server per Kerberos realm. 'kpasswd' servers are used to change your password, although the admin server will be used if no kpasswd server is listed. 'krb524' servers are used to get v4 tickets from v5 tickets and are only used by v5 realms.
If the realm and site DNS domain are different, there will also be domain to realm mappings. For instance, if you have a domain-realm mapping '.mydepartment.mysite.com = MYSITE.COM' and try to contact a server such as 'myprinter.mydepartment.mysite.com', Kerberos will know to contact the realm 'MYSITE.COM' rather than the default, 'MYDEPARTMENT.MYSITE.COM'.
The Kerberos Configuration File Format
The Kerberos v4 and v5 configurations are stored in the data fork of edu.mit.Kerberos
.
This text is similar to that of krb5.conf
on Unix machines or krb5.ini
on Windows machines. The configuration tells Kerberos for Macintosh what realms exist,what Kerberos versions are supported by them, and where to find the servers. You shouldedit this file for your site by opening the edu.mit.Kerberos
file in a text editor that will save the file as pure text again, ie: BBEdit, emacs, or CodeWarrior; but not TextEdit (unlessyou use the 'Make Plain Text' command) or Microsoft Word.
Once you are done editing the edu.mit.Kerberos
file, you should log out,and then you may want to use the Edit Favorite Realmsfeature of the Kerberos management application to add your realms to the pop-up menu in the Login dialog.
Here is an example Kerberos configuration:
The [libdefaults]
section describes what the default behavior of the Kerberos libraries should be. You should always fill in the default realm. If you have Kerberos v5 at your site, you should also copy any other [libdefaults]
from your site'skrb5.conf
or krb5.ini
.

Kerberos for Macintosh 5.5 now honors ticket_lifetime
entries in[libdefaults]
. However, if you have set a ticket lifetime default in the GUI Kerberos managementapplication preferences, it will override this value.
The [realms]
and [domain_realm]
sections refer to Kerberos v5 realms.If your site is v4-only you should omit these sections. Otherwise just copy these sections fromyour site's krb5.conf
or krb5.ini
.
The [v4 realms]
and [v4 domain_realm]
sections refer to Kerberos v4 realms. If your site is v5-only you should omit these sections. Otherwise you will need tocreate entries for each of the Kerberos v4 realms at your site. You should not specify astring_to_key_type for v4 realms anymore, because that information will be ignored - KfMwill automatically determine the correct one to use.
DNS Configuration
Some sites have configured their DNS servers to provide information about local Kerberos realmconfiguration, such that users need only a minimum configuration file and instead can getthe rest of the Kerberos configuration information over the network.For more information about DNS, see the Using DNSsection of the Kerberos V5 System Administrator's Guide.
System Preferences Mac
You should always have a configuration file that has a [libdefaults]
sectionwith a default_realm
specified. Otherwise, getting Kerberos tickets at logintime may fail.
If your Kerberos realm is named the same as your domain name, e.g. your domain name = foo.bar.edu andyour Kerberos realm = FOO.BAR.EDU, you do not need any more information in your local configurationfile, assuming all the realms you need to access have DNS records.
Otherwise, you also need a [domain_realm]
section, mapping your domain to the appropriaterealms. You can omit the [realms]
sections of the configuration file.
DNS configuration of realms only applies to Kerberos v5, so unless your site does krb524 on the server,you will need to include v4 information in a local configuration file.
If you want to disable DNS lookup of Kerberos realms on your Macintosh, uncheck the 'Configure additional realms automatically using DNS' checkbox in the Kerberos application's edit realms dialog or add the line:
to the [libdefaults]
section of your Kerberos configuration file.
