The Libyan historian Hadi Bulugma produced a series of books in Arabic on the history of Benghazi entitled بنغازي عبر التاريخ. He also made an abbreviated English version, the first volume of which (I am not sure that the second and third volumes were ever finished) concentrates on the geography and geographical history of the city. Here is a PDF of the book.

As a research aid, the Libyan sociologist Mustafa al-Tir (مصتفى عمر التير) published a bilingual English-Arabic bio-bibliography of sociologists and anthropologists in Libya in the early 1980s. In it, he writes:
“Producing bibliographies and indexes, whether general or specialised, is an important concern of those organising or propagating knowledge in society…Bibliographies and indexes are, of course, essential for the development of scientific research…
I have noticed on more than one occasion that many Libyan planners and scholars ignore sociological studies which have been carried out in their own society…and that some planners seek the help of specialised experts in social sciences from abroad while native experts, no less competent and probably much more so, because of their knowledge of the language, values and systems of this society, are available…The wrong lies in their complete negligence of the works of their native colleagues.
I believe that the negligence on the part of many students, planners and specialists of the works of Libyan researchers in social sciences is due, partly at least, to their failure to recognise the availability of local experience and their ignorance of the works of Libyan researchers.”
