Annals of the Astrophysical Observatory of the Smithsonian Institution
Volume of the Annals of the Astrophysical Observatory of the Smithsonian Institution, published in Washington by the Government Printing Office in 1900, recording government-funded research on infrared spectra and solar radiation for scientific readers. Its plates are scientific charts: a refraction-index curve plotted on fine grid paper, a vertical strip of ruled lines with sloped trend lines, a spectral intensity trace with a sharp central peak, and a temperature-over-time plot with labelled curves and hand-placed data crosses. A designer could borrow the clean grid layouts, hand-drawn curve lines and plain tabular labelling for minimal infographic work.
