The “Select All” tool is a popular feature we wanted to highlight separately.
It’s primarily used by new users when they want to mark all books in a series read at once, and aren’t interested in rating books or adding any tags or notes to them.
You could also use this if you wanted to remove all non-fiction books or series you aren’t interested in from an author’s “Still to Read” count.
Using the author David J. Gatward as an example – let’s say you want to mark all books in the DCI Harry Grimm series as “Read”. Just click the icon above the numbered list:

Then choose the “Read” status from the popup:

A confirmation popup will appear. Click “Ok” to proceed. A green checkmark will appear to show your update was successful, and you’ll see that all the books are now marked as read.

Important Note: This will only affect the books without a status. If you read the first two books in a series, and later decided to mark the rest as “Not Interested”, the tool will only update the remaining unread books, preserving your existing history.
