To find the total number of books, you can multiply the number of students by the number of books each student has.
In this case, you have 7 students and each has 8 books. The calculation would be:
\[ \text{Total number of books} = \text{Number of students} \times \text{Number of books per student} \]
So,
\[ \text{Total number of books} = 7 \times 8 = 56 \]
Therefore, the total number of books is 56.
