The library of the European Southern Observatory exists in its holdings since about 1970. The library is still a small one. It contains about 15–20000 books, 240 journal titles, approximately 70 m shelf-space for Observatory Publications and has about 220 square meters surface area. With about the same size we have a second library in La Silla in Chile, the mountain where our telescopes are installed. In Garching we have one and a third (!) librarian(s) and in Chile one librarian as staff. The question is: is it possible and is it necessary to computerize such small libraries and how can we do it with such limited personnel? The answer is yes; it is possible and even worthwhile.
