If you already have a list of your books from another source, you may want to use the import feature. Clicking on add books from the my books page gives you a blank search page. On the top right of this screen is a link to import books and a link to manually add books.
Anyone can manually add books, but please search first to prevent adding duplicate entries to the database. If a book is at Amazon or Barnes and Noble, searching for the book will import the details. You can search by author, title or ISBN. You can restrict the search to title or author by clicking on more options. Searching for ISBN or ASIN (for Kindle format) is the easiest way to find or import a particular edition.
You can use the explore menu to find various types of lists, if you don’t want to search for every book. You can also look at other people’s shelves to find interesting books. You can find people through the friends page and from book pages. On a book page, look for reviews and click on the profile picture (avatar) on a review you like or agree with. Some profiles are private, but most are not.
Each different format (hardback, paperback, e-book, audio, etc.) is a separate edition. Each new edition is added or imported to the database as a new book and then must be combined with the other editions. You can ask a Librarian to combine editions for you.
In most places, the edition of the book that is shown is the one that has been shelved the most times. If you want to change a book on your shelf to a different edition, click on other editions on the top right of the book page. When you find the correct edition, click on switch to this edition. If you want to review two or more editions of a book, click on review this edition.
There is a find duplicates function on the my books page to help you find any books you may have added twice.
