HARDWOODS

OXFORD/PRL/NCSU DATABASE

Coded at the Department of Wood and Paper Science, North Carolina State University, Raleigh, NC, U.S.A., from information from L. Chalk, Department of Forestry, Oxford; Brazier and Franklin, PRL (1961. Identification of Hardwoods. A Microscope Key. For. Prod. Res. Bull. 46); additional data from post-1950 monographs and personal observations by E. A. Wheeler (NCSU). [note: the North American Hardwoods Database is a subset of this Hardwoods Database]

SOFTWOOD DATABASE

Coded by Webster Hatley, Department of Wood and Paper Science, NCSU, based on Phillips (1948, reprinted 1970. Identification of Softwoods. For. Prod. Res. Bull. No. 22) and observations by Hatley.

FIBER DATABASE

Coded by A. Smith, Department of Wood   Paper Science, NCSU, using information from W. A. Cote (1980. Papermaking Fibers. Syracuse Univ. Press), R. A. Parham and R. L. Gray (1982.

The original GUESS program had several other databases - CTFT and IPT, but I have not included these in this program as permission was obtained to use them with the original GUESS program only.
