Infrared spectra between 2.3 and 196 were taken
towards a sample of 45 compact HII regions using the two
spectrometers (SWS and LWS) on board ISO. The primary goal is to
determine the distribution of element abundances in the Galaxy,
although there are also many other uses of this database.
The spectra contain a wealth
of information on the ionized gas and the associated photodissociation
regions through the atomic fine-structure lines and on the dust
properties via the dust emission bands and the continuum. Significant
variations are found from source to source in both spectral shape and
content. The sample of HII regions spans a wide range in
galactocentric distance
(from 0 to 22 kpc) enabling to investigate the variations of the
nebular properties across the Galactic plane. The
observations and the data reduction are described in detail in the
present paper. The ISO spectral catalogue of compact HII regions
contains the combined SWS-LWS spectra for each of the sources, the
fluxes of the atomic fine-structure lines and hydrogen recombination
lines, and an inventory of the spectra in terms of molecular lines,
dust and ice bands.
