Perhaps the most significant development in the early history of FORTRAN was the decision by the American Standards Association (now American National Standards Institute (ANSI)) to form a committee sponsored by the Business Equipment Manufacturers Association (BEMA) to develop an American Standard Fortran. The resulting two standards, approved ...
This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.

MINPACK is a library of FORTRAN subroutines for the solving of systems of nonlinear equations, or the least squares minimization of the residual of a set of linear or nonlinear equations. The NAG Fortran Library is a collection of mathematical and statistical routines for Fortran. NOVAS is a software library for astrometry-related numerical ...
One of the major features of FORTRAN 77 was the CHARACTER string data type. Use of this data type dramatically simplified character manipulation in Fortran programs – rendering almost all uses of the Hollerith constant technique obsolete.
SLATEC Common Mathematical Library is a FORTRAN 77 library of over 1,400 general purpose mathematical and statistical routines. The code was developed at US government research laboratories and is therefore public domain software.
The additional features of subsequent standards, up to Fortran 2023, are described in the Fortran 2023 standard document, ISO/IEC 1539-1:2023. [2] Some of its new features are still being implemented in compilers. [3] Details can also be found in a range of textbooks, for instance [4] [5] [6] and see the list at Fortran Resources.
High Performance Fortran (HPF) is an extension of Fortran 90 with constructs that support parallel computing, published by the High Performance Fortran Forum (HPFF). The HPFF was convened and chaired by Ken Kennedy of Rice University. The first version of the HPF Report was published in 1993.
