What the records hold
Open Library’s publisher page groups politics, biography, children’s fiction, dictionaries, drama and cartoon collections under the Nairobi house. The count of twenty-seven works is a library figure, not a warehouse audit. Titles move when cataloguers merge or split records.
Two ISBNs are printed in the Books-by-ISBN Kenyan list for this prefix: Sibi-Okumu 2005 and Seroney 2009. Other titles appear under author names without a digit string on that particular index page. Look the book up before you cite the number.
