'Adressbuch' (address book) is a very transparent word. It is made up of 'Adresse' (address), the linking '-n-', and 'Buch' (book). So it is literally a book for addresses.
Früher hatte jeder ein kleines Adressbuch aus Papier.
In the past, everyone had a small paper address book.
Pay attention to the difference between dative and accusative with the preposition 'in'. You enter a number 'ins Adressbuch' (into the address book; accusative, direction), but you look for a number 'im Adressbuch' (in the address book; dative, location).
Ich trage deine E-Mail-Adresse sofort in mein Adressbuch ein.
I'll enter your email address in my address book right away.
Common verbs in connection with 'Adressbuch' (address book) are 'eintragen' (enter), 'speichern' (save), 'aktualisieren' (update), 'nachschlagen' (look up), and 'löschen' (delete).
Kannst du bitte den alten Kontakt aus deinem Adressbuch löschen?

directory / index
'Verzeichnis' and 'Adressbuch' both have to do with organized information. A 'Verzeichnis' is the more general term for a list where you can find things, names, or files. An 'Adressbuch' is more specific: it contains contact details such as names, addresses, phone numbers, or email addresses. The words can be confused because an address book is a special kind of directory / index. When the topic is contacts, 'Adressbuch' sounds more natural. When the type of list is open or the topic is files, 'Verzeichnis' fits better.
