Research Laboratories Reports
The primary publication that reported work undertaken in the Laboratories was known as a "Research Laboratories Report" (RLR). These reports were numbered sequentially.
The first (No. 1) RLR was produced in 1931 and titled "Ringing Efficiency of Two Siemens Neophone Handset C. B. Telephones" by G.N. Smith. Early RLR's were single page documents and known as "Test Reports".
Around 115 reports were produced each year. A few RLR's were cancelled and never issued. From about 1975, RLR's were given a security classification - one of Proprietary, In-Confidence or Confidential.
Copies of all RLR's are held at the National Archives in Burwood, Victoria, Australia.

Note that the above report is signed by S. H. Witt, the first Director of the Laboratories.

The most prolific publisher of Research Laboratories Report was John Semple with a total of 110 reports.

“Personal Recollections of Telecom Research Laboratories 1981 to 2005”
When TRL closed in 2005, this last RLR no 8587 was printed. A copy was also added to the complete set of RLR's that were archived at the National Archives of Australia.

A "Branch Paper" was another publication reporting Laboratories work and used from the late 1960's to the mid 1990's. The concept of a Branch Paper was to "fast track" the reporting process because production of RLR's had a long lead time. In the listings, tabs (htm) or sheets (Excel) at the bottom of the page select different branches.

Review of Activities and New Horizons
A yearly glossy magazine entitled "Review of Activities" was published from 1971 to 1992 when it was replaced by an even glossier publication entitled "New Horizons". Both magazines were targeted at the general public. Files are in PDF format and searchable.

The "Telecom Researcher" was published on an ad hoc basis from 1988 to 1991. The publication was intended to make the important work of TRL understandable to both informed and lay readers.

Published from 1992 to 1994. Took over from the "Telecom Researcher"
> Future Focus May 1995
Published in the early 1960's.
