Ledermann describes the series as follows:

This series of short text-books is primarily intended for readers who study mathematics as a tool rather than for its own sake. The aim is to cover the topics which are usually included in courses of mathematics for scientists, engineers and statisticians at Universities and Technical Colleges. Each volume is made as nearly self-contained as possible, with exercises and answers, and a few of these books should provide enough reading material for the non-specialist throughout his mathematical studies. Thus each student will be able to build up his own text-book and adapt his reading closely to the syllabus he has to follow.

Generally, techniques are emphasized more than abstract theories, and the exposition has been kept on an elementary level. When it was not feasible to give a rigorous treatment, the underlying assumptions are fully explained.

The books contain various comments extracted from reviews:

'All the books contain worked examples in the text and exercises at the ends of the chapters. They will be invaluable to undergraduates. Pupils in their last year at school, too, will find them useful and stimulating. They will learn the university approach to work they have already done, and will gain a foretaste of what awaits them ii the future.'

- Times Educational Supplement

' . . . it will prove a valuable corpus . . . a great improvement on many works published in the past with a similar objective.'

- Times Literary Supplement

'These are all useful little books, and topics suitable for similar treatment are doubtless under consideration by the editor of the series.'
