Mobile libraries (also known as library buses, or  bookmobiles (en-us)) are small lending libraries usually housed in a specially adapted commercial vehicle, although other transport modes have been used, see Bookmobile on wikipedia. Usually they follow a regular route stopping for a fixed interval at a number of locations. The routes are repeated at a suitable interval to both allow adequate coverage of the target area and to allow time for users to read the borrowed books. In Britain this typically means a 3 week service interval for the route and half-hour stops at each location.

The route pattern can be mapped as a route relation as for any other bus route. In some cases, the route pattern can be irrelevant (e.g., mobile libraries that visit a different place each day of the week, staying there one morning or one afternoon). You can still use a site relation instead of a route relation to map all the stop points of the mobile library.

Tags to use in combination

opening_hours=* - a very important tag. The exact syntax for bi- or tri-weekly opening is not exactly clear, but the consensus seems to be week 1-52/3 We 10:00-10:30 for something which opens for half-an-hour on every third Wednesday starting on the first week of the year. (There are very few instances of this in taginfo).

Similar tags

  • amenity=library - a regular library. A different tag is needed because there may be several tens of mobile library locations in an area served by a very small number of normal libraries; also the relevant opening hours are so short they cannot be equated with normal libraries as comparable amenities.
