Hi, Martin. Welcome to the Discussions.
When you install a font via the Install button in Font Book's font preview window, it installs (copies) the font to the library you've specified as the default in Font Book > Preferences, e.g.
User: your Home > Library > Fonts folder
Computer: the Macintosh HD > Library > Fonts folder.
See
"Font Book 2.0 Help: Installing fonts", which can also be found in Font Book > Help > Font Book Help.
In reality, what appears in the Computer collection (which IMO should probably be called a library) is actually the union of the fonts in the Macintosh HD > Library > Fonts folder and the Macintosh HD > System > Library > Fonts folder.
In the Collection column, items above the horizontal dividing line are more properly considered
libraries, those below the line are better thought of as
collections.
I like to more precisely define Libraries (above the line) as the union of one or more folders containing the actual font files. Collections (below the line) are merely lists of fonts, i.e. pointers to the fonts themselves. I'll use these definitions in the rest of this post.
Once you've installed a font in a library, it can be added to any collection that you define. You do not need to install it twice.
If you move a font between libraries, it is physically moved from one library's folder to that of the other.
If you add a font to a collection, a pointer to the font is added to the list of fonts in the collection.
Deleting a font from a collection is different from Removing a font. Deleting a font from a collection merely removes it from that collection; the font remains installed. Remember, collections are merely lists of fonts containing pointers to specific fonts.
To Remove (uninstall) a font:
1. In the Collection column, select All Fonts.
2. In the Font column, select the font to be removed. The search field can help to locate the font.
3. Do one of the following:
• Press the Delete key.
• Select File > Remove “font” where font is the name of the font selected in step 2.
• Control-click the font, then select Remove “font” from the resulting contextual menu.
4. Confirm your intent to remove the font selected in step 2 by clicking Remove in the resulting confirmation sheet.
The font you selected in step 2 is moved to the Trash. If a font is Removed, its entry is also deleted from any collections containing (pointing to) that font.
One needs to be careful not toremove System fonts. Font book will generally prevent you from Removing most System fonts: you'll be able to go through the motions of Remove but the font will not be trashed. Such fonts, when selected in the Font column, display a lock icon in the Font Book border below the Preview area. Lucida Grande is a good example.
To better understand Font Book, I recommend you read the Apple Technology Brief
Fonts in Mac OS X (PDF).
