Dewhirst Classification

1966, revised 1982, 1998, 2007, 2014

The Subject Classification

The subject classification used in the library is similar to, but not identical with, that used in Astronomy & Astrophysics Abstracts. To find what books the library has on a particular topic, first identify the general subject area (Main Groups Roman I - XVI) and then look within that group for the more precise subject number. At the end of many of the subject numbers notes in brackets refer you to other subject numbers that contain books on related topics.

The first group (A-Q) covers General works of reference, and Subject specific works of reference. The second groups of the astronomy classification, I to VI, are concerned with types of literature (conference proceedings, astronomical tables, etc.); with methods of research (instruments, photometry, etc.); and with broad areas of astronomy like dynamical astronomy and theoretical astrophysics.

These are followed by groups VII to XII, which cover knowledge about things in the Universe; the Sun, planets, stars . . . arranged in an obvious way.

Finally groups XIII to XVI cover non-astronomy: Physics; Mathematics and Computers.

Within many of the groups the earliest subject number is for more general books and the numbers that follow are for narrower topics. A general principle used in giving a book a subject number is to prefer things in the Universe to ways of studying them; e.g. for Solar Radio Astronomy look under Sun rather than Radio Astronomy, and for Extragalactic High Energy Astrophysics look under Galaxies rather than under general astrophysics.

Please note this scheme is not universally applied, even in the IoA Library, dissertations, observatory publications, rare-books and large-sized atlases all have their own (non-Dewhirst) shelf-marks.
