Giant left atrium is extremely rare in the paediatric population, especially in asymptomatic cases. We report a 5-year-old child with a giant left atrium due to “non-rheumatic” mitral valve regurgitation that presented as a stroke secondary to atrial tachycardia. This case is noteworthy for the unusual “silent” manifestation of a giant left atrium.

Janheinz Jahn's Bibliography is the most useful reference work that bibliographers of African literature have yet produced. One may wish to quarrel with Jahn about his definition of “neo-African literature” or about some of the material he has chosen to include (e.g., unpublished manuscripts, sermons, travel books, political works, monographs) as well as some he has chosen to exclude (e.g., literary works by white African writers, collections of folklore), but one must applaud his thorough documentation and multilingual approach. No other bibliography of African literature has been so comprehensive and so accurate.

However, Jahn himself is aware that “there is no bibliography without gaps,” and he has invited others to help him “fill in these gaps and correct errors” (Jann, p. ix). It is hoped that the following list of additions and corrections will prove useful not only to Jahn but also to librarians, literary scholars, and other bibliographers. It is not to be taken as a complete list, for I have had neither the time nor the resources to check all of Jahn's entries or to search in more than a few libraries for missing titles. Of necessity my emphasis has been placed on materials written in European languages. I would encourage those who are aware of further errors and omissions to publish similar lists so that a more definitive bibliography of African literature can be prepared.

In the age of post-neoliberal globalization, complex interdependence has resulted in the integration of many economies and the industries within them and led to varied national and subnational political and economic responses. These forces have enabled the rise of a new political economy that requires the contextualized comparative sector approach (CCSA). This article advances a research agenda that contends theoretical and empirical leverage for explaining heterogeneity and assessing generalizability is gained by taking contextualized comparisons to the sector level of analysis. The CCSA identifies the multidimensional effects of sectors, uncovering new sites of inquiry connected to sectoral structural attributes, context-specific sectoral organization of institutions, and social and political constructions of sectors. Sectors are thus contexts that are embedded in multilevel contexts involving state and nonstate actors alike. Scholarship on industrial policy, technology and innovation, environmental transition, and regulation and governance demonstrates the analytical power and theoretical value of combining contextualized comparisons and sectoral analysis, which have been overlooked by the overly macro- or micro-level studies dominant in international and comparative political economy. The various strategies of the approach and a stepwise discussion of a research design underscore the possibilities for theory development and testing, adjudication of competing explanations, and case-specific discoveries.

Given the fact that we are able to agree on a set of categories for the collection of material on early nationalist movements in Africa, it is necessary also to ask whether or not the form in which the material is gathered is important. Our answer would be: it is essential to the secondary analysis of the oral history material that it be put in such a form that “more than” and “less than” questions be answered by its use when material from one or more countries is compared with that from other areas. If in comparing data on early nationalism from one area with those of others we are not interested in saying area A has more of this or that than area B, then quantification serves no useful purpose. However, we would contend that such statements are crucial in several ways. First, they allow us to compare areas more precisely, and, secondly, such data allow us and others the privilege of utilizing them to test theoretical formulations already present in the literature. Thus, if African socialism, as many theorize, denies the usual Marxist statements that socialism originates from the alienation felt by political thinkers and the masses as a result of the industrialization of the society, then early nationalists, many of whom were socialists in orientation, should be compared so as to see whether they were in fact alienated from their society--who were more so, and where were the early natiionalist movements more and where were they less socialistic, and where were they more and less alienated. If the informants who can remember the early nationalist movements are available, then such questions can be answered when researchers are made aware that these data may have, eventually, to be coded into more than, and less than, categories.

The African-American Institute quietly rounds its first decade this year, as vastly transformed within during this eventful period as Africa has been without. The Institute's anniversary marks a significant milestone in the history of contemporary U.S. - African relations. The event is perhaps no less noteworthy for the history of area-oriented private American organizations.

The early work of the Institute addressed itself mainly to assisting African students and visitors in this country, and to informing an American public still largely unaware of Africa's growing ferment. It was in 1956, for instance, that AFRICA REPORT began publication, quickly gaining for itself an influential place as America's leading publication on contemporary African affairs.

This bibliography attempts to list all known theses on sub-Saharan Africa accepted by the University of California at Berkeley, and catalogued by the University Library through January, 1969. The earliest item is dated 1914. The list was compiled from a card file of theses arranged by academic department which is maintained by the Library's General Reference Service.

The availability of theses on interlibrary loan is indicated by symbols following the number of leaves (L) in the thesis. An asterisk indicates that the Library has catalogued more than one copy of a title, and that the second copy may be borrowed on interlibrary loan. The symbol # indicates that the Library's Graduate Social Science branch has an uncatalogued copy of the thesis which may be borrowed. Absence of these symbols indicates that the title is not available on interlibrary loan. Photocopies of all M.A. and those Ph.D. these completed before September, 1962 may be purchased from the Library's Photographic Service; those Ph.D. theses from September, 1962 on, from University Microfilms, Inc.

The bibliography is in two parts. The first part contains those items which cover more than one country, and is divided into General, Central Africa, East Africa, and West Africa; the second part, arranged by country (present name), lists those titles dealing with only one political unit.

Any library investigation must have a bibliographical starting point. In the Africana field, for whatever aspect of African life one is concerned with, the starting point is Theodore Besterman's A World Bibliography of Bibliographies, the third and final edition of which was brought down to 1953 ana published in 1955. This massive 4-volume compilation contains 13 columns of entries under general heading: Africa. Entries for individual subjects, countries, and peoples should also be consulted. For the period since 1953, the bibliography of bibliographies section of the national bibliographies of European countries, South Africa, and the National Union Catalog of the United States should be consulted.

The recent dramatic emergence of tropical Africa to the center stage of international affairs has raised African studies to a position of grave national concern. If the new African nations are faced with the problems of adjusting in all too short a time to the responsibilities and tasks of independence, we on our side are faced with equally grave problems in meeting our responsibilities to them. In diplomatic relations, business and industrial contacts, and education and technical assistance programs, our critical need now is for a detaile understanding of these diverse nations.
