This page is devoted to issues affecting those who are rescuing historical weather data for submission to the reanalyses data repositories. Finding, imaging (maybe) and digitising the data may just be a starting point for you, especially if you are working with data you are not intimately familiar with. Re-casting this data in a format and at quality level you feel comfortable with raises a number of concerns, many of which will be common to the data rescue community.
As questions are posted and answers are given, you should hopefully develop here the confidence to submit your datasets into these worldwide repositories.

Some international data rescue and integration efforts:
The International Surface Pressure Databank collects land station and marine surface and sea level pressure data.
The International Surface Temperature Initiative is developing a Global Land Surface Databank which will take all steps of data rescue from images of any meteorological variables to keyed-in temperature observations. There is a series of blogposts on the recently beta version released global land surface databank at http://surfacetemperatures.blogspot.com/ and a static summary at www.surfacetemperatures.org/databank/ . The latter includes a pdf describing how to submit the data of digitized observations.
ISTI has many activities as part of its data rescue task (described here).
The activities of the Atmospheric Circulation Reconstructions over the Earth working group on data rescue are described here. ACRE coordinates with the World Meteorological Organization Data Rescue, IEDRO, and others as well as ISTI and ISPD and facilitates data rescue for these and other organizations.
The International Environmental Data Rescue Organization (IEDRO) works to rescue and digitize historical environmental data at risk, creating a safer and better global society. To help, volunteer, donate, or shop .
oldWeather is recovering historical weather observations from the logbooks of the Royal Navy; the US Navy, Coastguard, and Coast Survey. It's a citizen science project, with a large community of volunteers reading and transcribing the logbooks. See the website and the blog.
