Remember the choice of preservation media is only one small part of the whole Digital Preservation Strategy; make sure you plan to use all known best practice from the very outset of the project. One of the first and most important issues to consider is "who is going to 'own' this valuable resource long after your project has finished?" This ownership will come with responsibilities to protect and look after the data (whether it is on CD-R or any other media). This will require an ongoing budget - part of which will be needed to cover future migration to new storage media.

Whilst CD-R has, over the last few years, been the de facto choice for preservation, DVD-R is fast becoming a preferable alternative. DVD-R discs hold up to 4.7 GB of data compared to a CD-R 700Mb and there are an increasing number of recordable DVD drives available (which also read/write CD-R). If your project is in the early stages, or you have not yet started archiving to CD-R, you may want to look at DVD-R as an option
