JKUAT – Karen campus library was founded in February 2006 in the former Makini School library. It started with less than 100 volumes, most of which were loaned from the main campus library in Juja. There were initially two library staffs, transferred from Juja. The seating capacity of the library was 40 and there were two wooden bookshelves.
With the increase in student enrolment, the library building became inadequate and this triggered the need for more library space, facilities and resources. The library building was expanded between 2007 and 2008 resulting to the current building. During the expansion process the library service was accommodated temporarily in the ACE communication building.
The library building has a seating capacity of 250 users. The current collection of print materials is at 4368 volumes. Materials are classified using the Library of Congress Classification Scheme and catalogued online using Koha Integrated Library Management System. All library materials can be accessed through the Online Public Access Catalogue (OPAC).
Through the Kenya Library and Information Services Consortium (KLISC) a variety of e-journals and e-books in various subject disciplines have been subscribed to by the university. The university also subscribes to the LexisNexis database for the School of Law.
There are two computer laboratories with a total capacity of 30 computers. These laboratories are used for research, assignments and access to electronic resources. All library e-journals and e-books are accessible on and of campus. Access has been made possible by installing Ez-proxy which is a software that facilitates remote access to electronic resource.
