7 Campbell Collections @UKZN Digital microfilm scanner Obsolete technology Preservation of microfilms Newspapers and MSS on microfilm Data transfer Application to DISA

8 Digitising microfilm Samples were tested using the following: 1 bit at 300dpi 1 bit at 400dpi 1 bit at 600dpi 8bit greyscale at 300dpi with thresholding at 128 8bit greyscale at 400dpi with thresholding at 128 8bit greyscale at 600dpi with thresholding at 128 IFLA Newspaper Conference, New Delhi, 26-28 February 2010

9 Comparisons Sample 1: Scanned on flat bed scanner at 300dpi 8bit greyscale from unbound original Sample 2: Scanned using Minolta MS7000 microfilm scanner at 300dpi 8bit greyscale – microfilm copy looks as though it was bound One would have to conclude from this example that perhaps the microfilm was not captured correctly IFLA Newspaper Conference, New Delhi, 26-28 February 2010

10 OCR recognition It would be obvious that the rate of word return from the previous two samples would be far greater in the first image than it would be for the second image Conclusion Some microfilms are better than others – the resulting scan is as good as the original microfilm IFLA Newspaper Conference, New Delhi, 26-28 February 2010

12 OCR’ed text Big no to constitution as elections draw near 11,HOUSANDS of peo-ple have rejected the Government's new constitution under which elections for In-dian and coloured chambers of Parlia-nent are to take place n August. Reports from around the country talk of feverish activity as the biggest issue facing the country nears its climax."The elections, to be held on the 22nd and -28th of August, is seen as an issue which con-cerns all South Africans. The African com-munity in particular is " leading the call for a boycott of the elec` tions.Mr. Popo Molefe, the national secretary of the United Democratic Front (UDF), said the central issue was the 'denationalisation of the African people'. 'We call on our peo-ole in Eldorado Park, Reiger Park, Acton- ville and Lenasia, to boycott the August elections. 'We call on our peo- ple to refuse to be partners in the crime of Apartheid against the majority of South Africans.' IFLA Newspaper Conference, New Delhi, 26-28 February 2010

13 Indexing  Manual indexing!  Encoded using the international Text Encoding Initiative (TEI) later mapped to Dublin Core (DC) metadata element set  Metadata capture: publisher, place and date of publication at journal/ newspaper level  Indexing of title, author and keywords at article level  xml based  Articles over several pages  English language IFLA Newspaper Conference, New Delhi, 26-28 February 2010

14 Capturing journal metadata Speak: the voice of the community Volume 2 No 3 DISA Digital Innovation of South Africa Durban, South Africa 2002 1684.5188.002.003.Jul1984 Speak: the voice of the community Volume 2 No 3 July 1984 16 pages Speak Community Newspaper Project Johannesburg July 1984 IFLA Newspaper Conference, New Delhi, 26-28 February 2010

16 Indexing results  Advanced searchability on all the encoded elements  By using terms from a thesaurus, language usage is standardised  Higher relevance of returned hits  Added intellectual input IFLA Newspaper Conference, New Delhi, 26-28 February 2010

17 However …  Human indexing is time and labour intensive  Training is required  Quality control is needed  Thesaurus management software is essential IFLA Newspaper Conference, New Delhi, 26-28 February 2010
