You can assign each book in your Library to a Series, which is a way to associate books together. Custom Series in Logos behave as a whole rather than separate parts.
The Logos Library organizes your books by default, allowing filtering by type, language, and more. For sets of books, Logos creates a Series and assigns all books to that series (i.e., all commentaries in a set). You can, however, create a custom Series. Each book can belong to only one Series.
Note: You can also create Collections in Logos, which provide another way to organize your Library. Collections are most important for searching in Logos because you can restrict searches in Logos to specific Collections.

View Books by Series
For sets of books, Logos creates a Series and assigns all books to that series (i.e., all commentaries in a set). To view existing Series, open the Library, click the Sidebar Button to ensure the filter menu is visible, and expand Series.
Note that many books are not placed into a Series by default.
Add a Book to a Series
With the Library open, select a book (not the hyperlinked title) and ensure the info pane is visible. Scroll down to Series.
Pro Tip: You can also hold down the Shift (macOS) or Ctrl (Windows) key to select and change multiple books at the same time.
Click Set Series and provide a custom Series name.
Remember, each book can be assigned to only one Series.
Note: To remove a book from a Series, click to edit the Series text and remove the text in the input field. If the book was part of a default Series (e.g., a commentary set), Logos will reapply the original Series to the book.
Examples
Here are two examples where Series can help your study:
1. Full Original Language Bible
When reading in a Greek Bible, if you type an Old Testament reference, Logos will not return results since your Bible is New Testament only. If you, however, add both the Greek and Hebrew Bible to a custom Series (e.g., “Original Language Bible”), as you turn between Old and New Testament books, Logos will switch between Hebrew and Greek as needed.
2. Custom Commentary Set
Logos allows you to prioritize books and commentary sets in your Library, but changing texts will attempt to stay within the same commentary set since they belong to the same default series. When viewing the NICNT Commentary in Mark, for example, turning to Luke will stay within the commentary set.
You can, however, create a custom Series of commentaries to tell Logos to switch between your favorite commentary for each Bible book as you switch passages.
