No, there are big ($6 million) plans for one in Nigeria too.
Olusegun Obasanjo Presidential Library Foundation [OOPLF] has sealed a $6.1 million contract with Ralph Applebaum & Associates (RAA), an American firm of designers and architects, for the development of the museum component of the Presidential Library project. RAA was responsible for the Bill Clinton Library and Holocaust Museum among others.
Former Nigerian High Commissioner to the UK, Dr. Christopher Kolade described the library as a repository of African objects and artifacts. He justified the rationale for initiating the Presidential Library project in the former president's home state (Abeokuta, 48 miles south of Lagos) and also organising a fund raising ceremony for it while still in office.
Kolade said it was global practice for a President of a nation to initiate such a project while in office, citing for example the incumbent President of the United States of America, George W. Bush who had raised more than $500 million for his library.
