SURVEY OF COMPUTER PROGRAM CATALOGS-IV 
“NAVAL ORDNANCE LABORATORY LIBRARY OF COMPUTER PROGRAMS'* 
The U. S. Naval Ordnance Laboratory ■'(NOL) has developed a 
subroutine library "to gather and to distribute computer subrou¬ 
tines and to prevent wasteful duplication. This system provides 
a method for programmers to obtain write-ups and decks for already 
existing routines which perform functions they want." While de¬ 
veloped primarily for the use of their own staff, NOL will pro¬ 
vide information to other workers upon request. As of May, 1971, 
they were grouping their programs under the following index head¬ 
ings (the number in parentheses indicates the total number of 
programs available in that class): 
1® Utility and Systems (38.) 
2. Programmed Arithmetic (0) 
3« Elementary Functions (3) 
4. Polynomials, root finders, special functions, non-linear 
equations (25) 
5. Differentiation, Integration, Differential Equations (11) 
6. Interpolation, Approximation, Curve Fitting (14) 
7. Matrices, Vectors, Simultaneous Linear Equations (10) 
8. Statistical Analysis (20) 
9. Operations Research and Optimization (1) 
10* Information Processing (4) 
11. Engineering Applications (0) 
12. Miscellaneous (0)

in each of the index categories can be obtained from: Leah E.

IDENTIFICATION OF BIOLOGICAL SPECIMENS BY COMPUTER 
A three-year project on identification of biological speci¬ 
mens by computer began at the Botany School, Cambridge, on 1 June 
1971. The project is funded by the Science Research Council, with 
Dr. S. M. Walters as principal investigator, assisted by Mr. R. J . 
Pankhurst and Ms. R. R. Cox. The project covers three main areas: 
1. Improvement of existing computer programs for the gen¬ 
eration of keys. A system for on-line keys will also 
be prepared.
