Ephemeral materials such as political party manifestos, resolutions, and reports. Reprints when they are not in the collections or when they are for a replacement. Reports on development projects but not development plans. Text books and similar publications intended to prepare students for examinations. Works that are wholly technical in character which duplicate information already available in Western language publications.
Exception is made when the work contains an extensive new vocabulary.
Extracts from journals, books and newspapers readily available. Commemorative volumes essentially eulogistic in character. Hagiographies, lives of saints, unless well known. If it is not there, the title should be examined carefully to see what it reveals about the study. If it is a class of material which is peripheral to the research and reference, then the question is whether it contains or constitutes something unusual or new, as well as whether or not it is a type of publication already well represented in the library's collection.
