The LabelLove website allows fans to donate money to the cause. People can also email firstname.lastname@example.org to find out about other ways to help out.
Dan Salter, a LabelLove organizer, said: "We've been amazingly inundated with offers of help and support on this idea, and we are going to concentrate on trying to organize a series of live events to help this cause. Based on the offers we've had already, this is looking likely."
The Twitter account @_label_love_ and the hashtag #labellove have been established to keep fans updated.
As labels assessed the damage from the fires, the Association of Independent Music (AIM) issued the following statement on Tuesday:
The London riots have caused the destruction of a warehouse in North London housing many of the UK's independent labels and artists. All the stock has been destroyed in the fire. This will lead to much hardship for the artists and labels affected.
AIM member labels should contact email@example.com with their immediate concerns. AIM is doing what it can to support all those affected at this difficult time.
Music fans can show their support for the independent label community, and help them survive this disaster, by buying a digital download of an album from any one of the digital retailers in the UK, as well as going to their local record store whilst stocks last.
This way the labels will be able to remanufacture their CDs and vinyl more quickly, to resupply the record shops who are also affected by the riots.
Alison Wenham, Chairman and CEO of AIM, the UK's Trade Association for the Independent Music Industry, commented: " This is a disaster for the music community, but with the fans' help, labels and artists will survive. Please show your support for the music community by buying a digital album from an independent label today."
