Vertical files or Information files have been used in libraries to store current information in formats which is too small to put on shelves e.g. newspaper articles, pamphlets, photos. With the growth of the Internet many of these information sources are now available online which brings into question the viability of maintaining a vertical file. Here is an article  from Canada which discusses the pros and cons of the vertical file.

A more recent concept is the Virtual Vertical File (VVF), which allows libraries to organise web links within subject groupings and provide access to them via library wikis and websites. Jamie McKenzie provides some insights into the possible role of the VVF. 

Below are several examples of different approaches to organising a VVF.
