O'Reilly is navigated using the tabs on the left side of the screen. The home page features a search box, recommended books, curated playlists referred to as "learning paths", and several other categories of content.  

There are several ways to find books in O'Reilly. If you are starting in the O'Reilly platform, you may want to browse for books by topic. 

To do so, first click on the "Topic" navigation item on the left. You can then select from a list of top-level topics in the drop down menu that appears at the top of the Topics page. Following this, O'Reilly will show you the titles that in that category, and allow you to drill down further into subtopics. 

On O'Reilly homepage, there is a large search box at the top of the screen. 

O'Reilly will search by keyword by default. You can select the 'Filter' button to search by title, author, or publisher. On most other O'Reilly pages, there is still a small search box available.

When you submit a search, O'Reilly will return all books that meet your search. O'Reilly searches the full text of its collection when you do the default keyword search, so the search is quite powerful and will usually return many results for simpler searches. Along with the results, O'Reilly provides you with many options to filter the results. 

Books will open to show some basic information, like the title, author, and publisher as well as a short description and a table of contents. To start reading the book, you can click "Start Reading Now" or can click on a table of contents item. 

While reading a book, you simply scroll through the chapter or section in your web browser. In the right corner, you will see several icons.

 This icon will allow you to add the current section to a 'playlist', a customizable collection of books, book sections, or videos you can create in Safari.

 This icon allows you to adjust the size of the text.

 This icon allows you to 'share' the book or section to social media.

When you select a piece of text in the browser using your cursor, you can choose to copy the text, add a permanent highlight marker, or add a note.
