AbstractAlmost 70 years ago Lucien d’Azambuja published the first “Cartes Synoptiques de la Chromosphere Solaire et Catalogue des Filaments de la Couche Superieure” (d’Azambuja 1928), a compendium of reduced solar observations covering the time period March 1919–January 1920. The compiled database gives both visual and quantitative measures of solar activity beginning with Carrington rotation 876. Since then, data through 1989 have been published in succeeding Cartes Synoptiques issues. The World Data Center A (WDC-A) for Solar-Terrestrial Physics has digitized several long term solar publications, including the numerical text portion of the Cartes Synoptiques. We present an overview of this extraordinary historical solar database. WDC-A is using current technology to meet user requirements for data management, analysis and distribution, has compiled over 100 Megabytes of historical solar data and made it available over the Internet as part of a continuing data rescue effort. The data can be accessed via the World Wide Web at http://www.ngdc.noaa.gov/stp.

Both academic and public libraries have, since the inception of the internet and the world wide web, experienced a seismic level of change when compared to the past. The impacts of such specific issues as social media, open access, and the digital divide, and how they change both the short and long term operations and planning for libraries, are considered here through the lens of recent research on these topics. Some attention is also given to gaps in the current research and recommendations are made for further study. Particular attention is given to ways in which these issues overlap for academic and public libraries.
