In this paper we show that if I is an index set and Xi an ormed space for each i2 I, then the ‘p-direct sum (i2IXi)p; 1 p1, is UBL (unordered Baire-like) if and only if Xi;i2 I ,i s UBL. IfX is a normed UBL space and (; ;) is a nite measure space we also investigate the UBL property of the Lebesgue-Bochner spaces Lp(;X), with 1 p< 1. In what follows (; ;) will be a nite measure space and X a normed space. As usual, Lp(;X); 1 p< 1, will denote the linear space over the eld K of the real or complex numbers of all X-valued -measurable p-Bochner integrable (classes of) functions dened on , provided with the norm
