Titles judged unsuitable for the Main collection but worth retaining are offered to SILS for possible inclusion and if rejected are classed in PZ8 or PZ8.1 in Wilson Annex. As a general rule, O level materials should be brought to the attention of the appropriate bibliographer for possible return to Acquisitions as they are usually not wanted in a research collection, while A level materials can be routinely cataloged for Davis or an appropriate departmental library. Other elementary and secondary textbooks received through regular channels are usually not added unless they support curriculum studies and should be brought to the attention of the appropriate bibliographer. Editions of fairy tales, folklore, and legends with substantial text can be left in PZ8 and PZ8.1 if so classed by the Library of Congress. Editions of fairy tales, folklore, and legends intended for younger children should be brought to the attention of a librarian as should any juvenile non-fiction title.
Art occasionally receives picture books.
Contact the librarian who may wish these classed with the illustrator in Class N, left in PZ, or transferred to SILS or Wilson Annex. Contact the librarian for a decision as to the suitability of any children's title received. Juvenile titles judged unsuitable for other collections but worth retaining should be classed in PZ or if non-fiction with the topic and shelved in Wilson Annex. The RBC is interested in children's books published before 1870 and some editions, particularly first editions, of important 20th century children's authors if they are in good condition. Additionally, any rare, expensive, or highly unusual item can always be submitted for RBC consideration if the cataloger has reservations about shelving it in Davis or Wilson Annex.
