First Published in 1994. This book focuses on the historical development of the library as an institution. Its contents assume no single theoretical foundation or philosophical perspective but instead reflect the richly diverse opinions of its many contributors. This text is intended to serve as a reference tool for undergraduate and graduate students interested in library history, for library school educators whose teaching requires knowledge of the historical development of library institutions, services, and user groups, and for practicing library professionals.

The zone where land and sea meet is composed of a variety of complex environments. The coastal areas of the world contain a large percentage of its population and are therefore of extreme economic importance. Industrial, residential, and recreational developments, as well as large urban complexes, occupy much of the coastal margin of most highly developed countries. Undoubtedly future expansion in many undeveloped maritime countries will also be concentrated on coastal areas. Accompanying our occupation of coasts in this age of technology is a dependence on coastal environments for transportation, food, water, defense, and recreation. In order to utilize the coastal zone to its capacity, and yet not plunder its resources, we must have extensive knowledge of the complex environments contained along the coasts. The many environments within the coastal zone include bays, estuaries, deltas, marshes, dunes, and beaches. A tremendously broad range of conditions is represented by these environments. Salinity may range from essentially fresh water in estuaries, such as along the east coast of the United States, to extreme hypersaline lagoons, such as Laguna Madre in Texas. Coastal environments may be in excess of a hundred meters deep (fjords) or may extend several meters above sea level in the form of dunes. Some coastal environments are well protected and are not subjected to high physical energy except for occasional storms, whereas beaches and tidal inlets are continuously modified by waves and currents.

The 1973 WHO classification of bladder tumours anticipated a probable need for eventual revision of the criteria for diagnosing papillary and flat bladder neoplasia. A workshop sponsored by the WHO consisting of pathologists, urologists, cytologists, oncologists and basic scientists interested in bladder tumours addressed this subject, and after a follow- -up meeting sponsored by the International Society of Urological Pathology, the classification and terminology used in this text were agreed upon. A major change is in the introduction of a new category: papillary urothelial neoplasm of low malignant potential. Many of the tumours previously designated as papillary transitional cell carcinoma, grade I now fall into that category. Another major change is in the designation of flat lesions, and this includes a definition of carcinoma in situ. Furthermore, a number of variant forms of urothelials carcinomas are included as well as new entities not recognized when the 1st edition was issued.

This classification is based primarily on the microscopic charac- teristics of tumours and, therefore, is concerned with morpho- logically identifiable cell types and histological patterns, as seen with conventional light microscopy. The term tumours is used synonymously with neoplasm. The phrase tumour-like is applied to lesions which resemble neo- plasms, clinically or morphologically, but do not behave biologi- cally in a neoplastic manner. They are included in this classifica- tion because they give rise to problems in differential diagnosis and because of the unclear borderline between neoplasms and certain non-neoplastic lesions. Synonyms are listed only if they have been used widely, or if they are considered to be helpful to the understanding of the lesion. In such cases, the preferred term is given first, followed by the synonym. Although the emphasis of this classification is on histological typing, in the examination of kidney tumours, consideration should be given to the degree of cellular anaplasia, the extent of local spread, vascular and lymphatic invasion, and the occur- rence of metastasis. The scheme of histological grading suggested here is as fol- lows: Grade I applies to the tumours that have the least degree of cellular anaplasia compatible with a diagnosis of malignancy; . grade II! applies to tumours with the most severe degrees of cel- lular anaplasia; and grade I! applies to those tumours in be- tween. This scheme is applicable to the carcinomas of the renal parenchyma and pelvis.

This revision of the book originally published in 1980 is the result of a collaboration among scientists from 10 countries. The authors include not only pathologists but also a urologist and a basic scientist. The second edition - containing 146 colour photographs - is considerably more extensive than its predecessor. A number of new entities, unrecognized in 1980, are included: prostatic intraepithelial neoplasia, which is commonly associated with carcinoma and may also be seen in a biopsy for elevated PSA; basal cell carcinoma; small cell carcinoma; paracrine-endocrine elements; variants of carcinoma; and stromal sarcoma. The criteria for the diagnosis of carcinoma have been expanded, including the minimal criteria. The Gleason grading system, based on growth pattern, is presented in detail. The WHO grading system, based on nuclear anaplasia and glandular differentiation, is more clearly defined.

Surface Hardening of Steels: Understanding the Basics is a practical selection guide to help engineers and technicians choose the most efficient surface hardening techniques that offer consistent and repeatable results. Emphasis is placed on characteristics such as processing temperature, case/coating thickness, bond strength, and hardness level obtained. The advantages and limitations of the various thermochemical, thermal, and coating/surface modification technologies are compared. Economic concerns and health and safety considerations are also addressed. Recent developments in the understanding of the relationships between microstructure and fatigue and wear performance are reviewed, as are more recently introduced surface hardening processes such as vacuum-related technologies, laser processing, CVD/PVD, and ion implantation. Methods for evaluating hardness patterns and depths of hardness for quality control and failure analysis are described. The book also reviews methods for measuring and controlling case depth, residual stresses, and distortion. Metallurgical comparisons are made between those processes that offer rapid heating and rapid cooling (self quenching) characteristics for example, induction hardening and conventional furnace hardening. While all of the surface engineering methods discussed enhance wear resistance, some such as electroless nickel plating, carbide salt-bath deposition, and chrome platingualso offer resistance to corrosion and oxidation. Wear and corrosion data are provided to demonstrate the benefits of each process.
