One of a series of errors made by departmental administrations this year has cost many students more than $14, according to a spokesman for Whitcombe and Tombs Ltd.

Reading lists and lists of required texts are normally made available to booksellers before the end of a year, in order to enable them to purchase sufficient quantities in time for the courses next year.

Mistakes by several departments have been alleged.

The first two texts listed in the University Calendar for Psychology II were ordered by booksellers.

The texts were L. J. Bischof's Interesting Personality Theories ($5.95) and Hall and Lindsay's Theories of Personalily ($8.10).

Large numbers were sold to students, some of whom understood from their first lecture that these particular books would not be needed.
