CIFtbx2 is a new version of a Fortran subroutine library for programmers developing CIF applications. The functions for reading and writing CIF data in CIFtbx [Hall (1993). J. Appl. Cryst. 26, 482-494] have been expanded and facilities for handling macromolecular CIF data and dictionaries have been added. The CIFtbx2 library facilitates applications involving all current versions of the dictionary definition language.
