The study set out to investigate the provision of sustainable internet access to public libraries in South Africa. The rationale of the study was to investigate how sustainable internet access can be provided to public libraries in South Africa and to determine how they have developed and are regulated. Internet access is a key driver in delivering information services to the users and a critical tool in facilitating information sharing regardless of platform and geographic location. Therefore, the level of information and communications technology (ICT) penetration in public libraries formed a critical part of the study as the provision of internet to these libraries depends on available ICTs. The study employed a survey design and used interview tool to collect data from nine participants. Questionnaire augmented interviews as they were used to collect data from 322 respondents. The study used the probability sampling technique to collect data from the participants. The purposive sampling technique was used to select the participants for the interview, whereas the stratified probability, proportional to size, and systematic techniques were also used to select respondents in the senior categories, namely heads of public libraries. This ensured a sample size of 331 out of a population of 1 621 selected for the study. The sample size consisted of nine directors and 322 head librarians. No sampling was done on the nine heads (directors) of provincial public libraries, as the nature of this population did not warrant further dissection due to its small size. A Microsoft Excel spreadsheet was used to analyse data. Questionnaires were analysed when they were returned and interviews were analysed when they were conducted. Written descriptions, tables and figures were used to present data in an elaborative manner. Data was also presented through frequencies and percentages. It emerged from the study that most public libraries (97%) were connected to the internet. The findings of the study showed that most public libraries (80%) were connected to the internet through the fixed lines and that each of the nine provinces had its own internet service providers (table 5.12). The study recommended fixed lines for internet access to be laid to all public libraries in South Africa and that a government agency be used as a dedicated internet service provider for public libraries across all the nine provinces. A further study was recommended about the application of an internet access model used by academic institutions to public libraries. / Information Science / D. Litt. et Phil. (Information Science)
