Hi, I'm a volunteer from the UK working with the National Teachers' Institute in Kaduna, Nigeria, to help them make better use of IT. NTI are a government organisation providing teacher training by distance learning. NTI headquarters in Kaduna has a library that they want to make more accessible to the student around the country and they are also planning to set up branch libraries nearer the students. At present they have started to set up a web library of electronic documents using Mambo and its DocMan module (http://www.mambodocman.com/). They would like to move from card indexes (inaccessible from outside the library) to a computerised catalogue that users all over the country can access. After that (long) introduction I have a couple of questions: 1. Can Koha be used as an interface to both the catalogue of physical books and the electronic books? The list of features on the website mentions virtual libraries but I couldn't find any more information. 2. Are there any Koha users in Nigeria? It would be very useful to be able to discuss how local issues (lack of electricity, difficult communications, etc.) have affected your use of Koha. Thanks, Kevin O'Rourke Interim Head of ICT NTI Kaduna
