After the first three issues of Volume 151, the next issue appeared as Volume 152 Number 4, and the remaining issues of Volume 151 as Volume 153 Numbers 5 through 9.
We have not used the mistaken volume numbers 152 and 153, but have identified these
issues instead as Volume 151
Numbers 4-9.
But the next volume of the Scholastic appeared as Volume 154, and we have
retained this volume number.
This means that Volume 152 and Volume 153 do not really exist.
