Beginning with the July, 1915 issue, the Monthly List of Changes in Personnel was incorporated into a publication, of a larger scope, which also contained a series of short notes and comments designed to be helpful, to station officials and the Central Office, in the conduct of Weather Bureau affairs. It was believed that a medium for the exchange of views, methods and tips would be of value to Weather Bureau personnel. To secure this desired result, every employee was invited to contribute any helpful suggestion or item of interest, which was forwarded to the Chief of the Bureau for approval and publication. These notes were not intended to supersede regulations, circulars or circular letters, nor regarded as instructions to be rigidly followed, but to conveyed an informal interpretation or application of the formal instructions. The Central Office believed that many experienced Weather Bureau personnel had developed effective yet simplistic work-flow methods that should be shared. Topics and Personnel was intended to serve as a clearing-house of ideas rather than imposing regulations.
The NOAA Central Library maintains the collection of Weather Bureau Topics and Personnel from July 15, 1915 through August 1965. There have been several title changes beginning with Topics and Personnel to Weather Bureau Topics in 1948 and finally Topics in 1961. The July 1941 issue is also called the Fiftieth Anniversary Issue, July 1891-July 1, 1941.
