To find the median number of citations, we need to arrange the numbers in order from smallest to largest.

12, 13, 13, 21, 22, 23, 25, 26, 31, 34

There are 10 numbers, so the median is the middle number when they are arranged in order. In this case, the middle numbers are 22 and 23. To find the exact median, we take the average of these two numbers.

(22 + 23) / 2 = 22.5

Therefore, the median number of citations issued per day is 22.5.
