I HAVE sometimes been asked whether I am conscious, as the present editor of THE LIBRARY WORLD, of the spirit and influence of its founder, James Duff Brown, and of his editorial successors, who included J. D. Stewart and W. C. Berwick Sayers. The answer is that of course I am—how could it be otherwise?

Abstract
Purpose
Most of optimal design or control engineering problems present conflicting objectives that need to be simultaneously minimized or maximized. Often, however, it is a priori known that some functions have greater importance than other. This paper aims to present a novel multi-surrogate, multi-objective, decision-making (DM) optimization algorithm, which is suitable for time-consuming simulations. Its performances have been compared, on the one hand with a standard decision-making algorithm (iTDEA), on the other with a self-adaptive evolutionary algorithm (AMALGAM*). The comparison concerns numerical tests and an optimal control task in induction heating.
Design/methodology/approach
In particular, the algorithm makes use of surrogates (meta-models) to concentrate the field evaluations at the most promising areas of the design space. The effect of the decision-maker is instead to drive the search to given regions of the Pareto front. The synergy between surrogates and the decision-maker leads to a greater effectiveness of the optimization search. For the field analysis of the optimal control task, a coupled electromagnetic-thermal FEM model has been developed.
Findings
The novel algorithms outperform both iTDEA and AMALGAM* in all done tests.
Practical implications
The algorithm could be applied to other computationally intensive multi-objective real-life problems whenever a preference between the objectives is known.
Originality/value
The combination of surrogates and a decision-maker is beneficial with time-consuming multi-objective optimization problems.

Abstract
ALTHOUGH the first Public Libraries (Scotland) Act was placed on the Statute Book in 1853, it was not until 1899 that the Corporation of the City of Glasgow was empowered to establish and maintain public libraries throughout the city. Between 1876 and 1897 four attempts were made to secure public approval for the adoption of the Public Libraries (Scotland) Acts, but when all these efforts proved unsuccessful, the Corporation decided in June, 1888 to include in a Local Bill for submission to Parliament, certain clauses conferring upon themselves the power to become a library authority. Promoted in 1899, the Bill became known as the Glasgow Corporation (Tramways, Libraries, etc.) Act 1899, and the library clauses passed through Parliament without opposition and received Royal Assent on 1st August, 1899. The powers conferred by this Local Act empowered the Corporation:

Abstract
THE re‐organisation of local government in Greater London and the resultant amalgamation of library authorities is viewed by many with considerable misgivings. The upheaval of staff, the loss of status for some senior officers, the general uncertainty for the future—these are very real consequences of the Act and they cannot be ignored. Many chief librarians will see the work of a lifetime, perhaps spent in building up a comprehensive and unified system, made virtually meaningless overnight.

Abstract
IT is well known that librarianship or library science and information work or information science as the common educational, professional and scientific discipline is everywhere undergoing great change and development. During its continual and relatively fast development, this discipline has at the same time to solve the increasing tasks connected with the problems of the so‐called information explosion.
