Last year the Library of Congress released Recommended Format Specifications (see post here) to serve as a guide for long term preservation and access to both analog and digital materials. As they move forward, and to maintain the currency of the guide, an annual review of the formats is being implemented. To this end, they are requesting feedback before March 31, 2015 that will be taken into consideration during this year's review. Feedback can be addressed to one of the email contacts here.
Additional information about the review process is available on The Signal.
