The presentation of the material follows the sequence given in the List of Contents. In this small collection Collar's lectures and, to a lesser extent, his Aeronautical Research Committee (later Council) papers predominate.
Section A (Biographical) is very slight but includes notes on his professional career sent to the Minister of Technology in 1967 (NCUACS 3.2.88/A.2) and a copy of R E D Bishop's Royal Society memoir (NCUACS 3.2.88/A.5).
Section B (Aeronautical Research Council) presents a sequence of research papers and papers dealing with matters of internal organisation covering the period 1935-80; of some interest are items NCUACS 3.2.88/B.13 - B.15 which relate to the 1958 Munich air disaster. Also included in this section are a number of research papers prepared while Collar worked for the Royal Aircraft Establishment during the war. It should be noted that a great part of Collar's Aeronautical Research Council papers were destroyed at his own request after his death.
Section C (Lectures, Broadcasts and Publications) is the most substantial of the collection. There are lectures on aeronautics and matrices and lectures to a wide variety of audiences on more general scientific topics, such as engineering education and science and society. In his later years Collar gave talks on humorous poetry, of which he was both very fond and extremely knowledgeable. A few sets of ms notes for these talks can be found at NCUACS 3.2.88/C.45.
Section D (Scientific Correspondence) is again slight, but what survives serves chiefly to illustrate Collar's interest in matrices, a field in which he was an acknowledged authority.
