While it is less of an issue in urban areas, library access can be an issue. A library that is a 30 minute walk from a family's home would involve an hour to reach and return from, and likely longer if they have a young child with them. Public transit may improve transportation time, but it adds cost. The cost of those transit fares may enable them to purchase several books at a more local charity shop. Ebooks may remove the necessity of going to a library, but that only counts if you have more local access to an Internet connection.
