This paper addresses issues arising in the systematic construction of large logical systems. We rely on a model-theoretic view of logical systems, captured by institutions that are in turn presented by parchments. We define their categories, and study constructions that may be carried out in these categories. In particular we show how limits of parchments may be used to combine features involved in various logical systems, sometimes necessarily augmenting the universal construction by additional systematic adjustments. We illustrate these developments by sketching how the logical systems that form the logical foundations of CafeOBJ may be built in this manner.
