The paper investigates how the type of business content found in the reading materials offered by a popular Business English course book as well as the degree of the content's relevance and usefulness, are perceived by pre-service students learning Business English as part of their university curriculum. Twelve groups of first year undergraduate students at the University of Economics in Katowice, with no prior experience of learning either Business English or the principles of business, were asked to compare pairs of texts related to three business topics: international marketing, management styles, and stock market investment. One of the texts in each pair was selected from the Student Book of the third edition of a widely used Business English course book (upper-intermediate or intermediate level), and the other, on the same topic, extracted from online repositories of business-related articles. The results of the student survey indicate that first year students, while appreciating the course book 'real-life examples' of successful companies, express strong preference for the Internet-based texts which provide them with the opportunity to acquire 'basic knowledge' related to specific business issues. The findings also appear to confirm the rationale behind integrating the two approaches: LSP (languages for specific purposes) and CBI (content-based instruction) in the tertiary education context, as well as the importance of properly selected professional content in fostering learners' motivation and engagement.
