In this time of rapidly increasing journal subscription costs and shrinking (or stable) acquisition budgets, it is imperative to acquire materials as effectively as possible. One method of doing this is to use citation analysis of the scholarly literature as a guideline. Citation analysis is the analysis of the references from a set of documents (such as an analysis of all of the citations from five years of College & Research Libraries or of all citations from geology dissertations at a university). Information received from the analysis includes: languages of items cited, age of items cited (to calculate a half‐life for the field), and rate of self‐citations. Broadus reviewed citation analysis, its use, validity, and reliability. In the past, citation analysis has been used in collection development to decide on the suitability of specific items (both journals and monographs), such as mentioned in Buzzard and Whaley. The method introduced here is to use the percentage of publication formats cited in the research literature to serve as a guideline for acquisitions budget breakdowns, i.e., percentages allocated to monographs versus that allocated to other formats, for each discipline. The reasoning behind this is that an effective method of acquiring materials is to purchase the materials that the library's clients will use in the formats in which they will use them. The key assumption is that the citations in a scholar's paper reflect the literature the scholar used.

This paper aims to investigate the idiosyncratic relationships between work and nonwork among dual-career professional couples (DCPCs) intentionally without children, considering individual members' role salience, nonwork responsibilities and care or career orientation.

Interview data from 21 Canadian and American couples (42 individuals) was used to explore the research question: How do DCPCs without children perceive their work-nonwork balance?

DCPCs without children are a heterogenous demographic. Some couples are career oriented, some care oriented, some exhibit both orientations, shaping their experience of work-nonwork balance. Unlike popular stereotypes, they do have nonwork responsibilities and interests outside of their thriving careers. Similar to their counterparts with children, they face conflicts managing work and nonwork domains.

Based on theories of role salience, work-nonwork conflict, enrichment and balance, the authors suggest that analyses of work-nonwork balance should include nonwork activities other than child caring. The authors further propose that the experience of the work-nonwork interface varies according to whether couples are careerist, conventional, non-conventional or egalitarian. The study also demonstrates that work-nonwork experiences are relational in nature and should be explored beyond a strictly individual perspective.

Low temperature co‐fired ceramics (LTCC) material is introduced as an excellent alternative to silicon, glass, or plastic materials for the fabrication of miniaturised analytical devices, though it is most widely used in the automotive and microwave industries. The paper aims to study the laser ablation of LTCC material.

This kind of green tape material is mechanised by excimer laser (KrF, 248 nm) and UV laser (Nd: YAG, 355 nm), and for the first time by infra‐red laser (1,090 nm). The optical photos and the scanning electronic microscope (SEM) photos of the LTCC ablated by different kinds of laser sources are given in this paper.

When using the UV laser, the tapered structure can be easily seen from the SEM photo. However, a kind of clear and perfect ablation of LTCC can be seen for the first time by the 1,090 nm infra‐red laser ablation.

The laser ablation of LTCC by optical fibre sources is discussed.
