Abstract
To the Editor, Sir, It was interesting to read W. A. P. Fisher's reply to J. Shapiro on that most engaging of subjects—fatigue. Both may be warmly praised for the frankness with which they expressed their personal opinions. The course of the discussion, however, prompts yet another view‐point to be stated concerning fatigue of aircraft in general rather than fatigue of helicopters in particular.

Abstract
The prevention of fatigue in bolts by controlled pre‐tensioning is investigated theoretically. It is shown that the effect of pre‐tension is to reduce the alternating load in the bolt and that the stiffness of the fitting plays an important part in this reduction. Fatigue tests on ¾‐in. B.S.F. bolts with various amounts of pre‐tension show how this reduction in alternating load can prevent fatigue failure. A warning is given against relying on the benefits of pre‐tensioning without ensuring that pre‐tension is maintained in service.

Abstract
Purpose
This paper presents recently published resources on library instruction and information literacy. It provides an introductory overview and a selected annotated bibliography of publications covering various library types, study populations and research contexts. The selected bibliography is useful to efficiently keep up with trends in library instruction for busy practitioners, library science students and those wishing to learn about information literacy in other contexts.
Design/methodology/approach
This article annotates 424 English-language periodical articles, monographs, dissertations, theses and reports on library instruction and information literacy published in 2021. The sources were selected from the EBSCO platform for Library, Information Science, and Technology Abstracts (LISTA), Education Resources Information Center (ERIC), Scopus, ProQuest Dissertations and Theses, and WorldCat, published in 2021 that included the terms “information literacy,” “library instruction,” or “information fluency” in the title, abstract or keywords. The sources were organized in Zotero. Annotations summarize the source, focusing on the findings or implications. Each source was categorized into one of seven pre-determined categories: K-12 Education, Children and Adolescents; Academic and Professional Programs; Everyday Life, Community, and the Workplace; Libraries and Health Information Literacy; Multiple Library Types; and Other Information Literacy Research and Theory.
Findings
The paper provides a brief description of 424 sources and highlights sources that contain unique or significant scholarly contributions.
Originality/value
The information may be used by librarians, researchers and anyone interested as a quick and comprehensive reference to literature on library instruction and information literacy within 2021.

NOTWITHSTANDING the fact that there exists a considerable amount of literature published in various forms on the subject of brittle lacquers and their applications to a multitude of diverse problems a brief resume of some of the general principles involved would seem not to be out of place.
