The University of Buea is the one university in the english-speaking part of Cameroon (which uses french and english as its main official languages). Quite a lot is made of appearance in this country, especially in official matters. This seems to be represented in this stamp as well, which is quite pronounced, using not only the prominent red, but also both official languages, the full official name of the country, the name of the ministry residing above the the university, the name of the university as well as the label “Bibliothèque / Library”. The center of the stamp is a logo, which is sometimes used by the ministry of higher education itself. This give the stamp quiet an official character.
As could be seen here, the stamp itself is made more official by its size.
Something that could be found in quite a lot of the libraries in Cameroon is an extra stamp on the side of each book. This marks the library book even more as such.
