We present the results of a comprehensive infrared, submillimetre, andmillimetre continuum emission study of isolated low-mass star-forming cores in32 Bok globules, with the aim to investigate the process of star formation inthese regions. The submillimetre and millimetre dust continuum emission mapstogether with the spectral energy distributions are used to model and derivethe physical properties of the star-forming cores, such as luminosities, sizes,masses, densities, etc. Comparisons with ground-based near-infrared andspace-based mid and far-infrared images from Spitzer are used to reveal thestellar content of the Bok globules, association of embedded young stellarobjects with the submm dust cores, and the evolutionary stages of theindividual sources. Submm dust continuum emission was detected in 26 out of the32 globule cores observed. For 18 globules with detected (sub)mm cores wederive evolutionary stages and physical parameters of the embedded sources. Weidentify nine starless cores, most of which are presumably prestellar, nineClass 0 protostars, and twelve Class I YSOs. Specific source properties likebolometric temperature, core size, and central densities are discussed asfunction of evolutionary stage. We find that at least two thirds (16 out of 24)of the star-forming globules studied here show evidence of forming multiplestars on scales between 1,000 and 50,000 AU. However, we also find that most ofthese small prototstar and star groups are comprised of sources with differentevolutionary stages, suggesting a picture of slow and sequential star formationin isolated globules
