FAQ: Is my access to an O'Reilly book through the Shapiro Library on a time limit?
There isn't a time limit in O'Reilly. On a book's main page, there is a "Time to Complete" estimate that provides an estimate of how much time it will take you to finish reading a book.
You can also see that estimate when you are reading the book. The estimate will be in the top left-hand corner.
According to O'Reilly, it will take me 20 hours and 7 minutes to read this book. But these 20 hours can be spread over weeks, months, etc.
