Abstract
Purpose
The purpose of this paper is to review the current LIS literature for document supply and related topics.
Design/methodology/approach
The paper is based on the scanning and reading of about 150 journals, reports, and web sites.
Findings
There is continued growth in freely available articles. There are dramatic development in open access initiatives especially in the US and some confusion in the UK. A study shows the dramatic impact on journal cancellations in a six month embargo environment with a likely increase in ILL. Publisher constraints on copying are a constant obstacle and those on e-books are now receiving more attention by librarians.
Originality/value
This is the only regular literature review that focuses on document supply and related issues.

Abstract
Purpose
To propose a categorization of the different conflation procedures at the two basic approaches, non‐linguistic and linguistic techniques, and to justify the application of normalization methods within the framework of linguistic techniques.
Design/methodology/approach
Presents a range of term conflation methods, that can be used in information retrieval. The uniterm and multiterm variants can be considered equivalent units for the purposes of automatic indexing. Stemming algorithms, segmentation rules, association measures and clustering techniques are well evaluated non‐linguistic methods, and experiments with these techniques show a wide variety of results. Alternatively, the lemmatisation and the use of syntactic pattern‐matching, through equivalence relations represented in finite‐state transducers (FST), are emerging methods for the recognition and standardization of terms.
Findings
The survey attempts to point out the positive and negative effects of the linguistic approach and its potential as a term conflation method.
Originality/value
Outlines the importance of FSTs for the normalization of term variants.

Abstract
Purpose
To propose a comprehensive and semi‐automatic method for constructing or updating knowledge organization tools such as thesauri.
Design/methodology/approach
The paper proposes a comprehensive methodology for thesaurus construction and maintenance combining shallow NLP with a clustering algorithm and an information visualization interface. The resulting system TermWatch, extracts terms from a text collection, mines semantic relations between them using complementary linguistic approaches and clusters terms using these semantic relations. The clusters are mapped onto a 2D using an integrated visualization tool.
Findings
The clusters formed exhibit the different relations necessary to populate a thesaurus or ontology: synonymy, generic/specific and relatedness. The clusters represent, for a given term, its closest neighbours in terms of semantic relations.
Practical implications
This could change the way in which information professionals (librarians and documentalists) undertake knowledge organization tasks. TermWatch can be useful either as a starting point for grasping the conceptual organization of knowledge in a huge text collection without having to read the texts, then actually serving as a suggestive tool for populating different hierarchies of a thesaurus or an ontology because its clusters are based on semantic relations.
Originality/value
This lies in several points: combined use of linguistic relations with an adapted clustering algorithm, which is scalable and can handle sparse data. The paper proposes a comprehensive approach to semantic relations acquisition whereas existing studies often use one or two approaches. The domain knowledge maps produced by the system represents an added advantage over existing approaches to automatic thesaurus construction in that clusters are formed using semantic relations between domain terms. Thus while offering a meaningful synthesis of the information contained in the original corpus through clustering, the results can be used for knowledge organization tasks (thesaurus building and ontology population) The system also constitutes a platform for performing several knowledge‐oriented tasks like science and technology watch, textmining, query refinement.

Abstract
Purpose
The purpose of this paper is to provide a review of the literature concerning interlending and document supply.
Design/methodology/approach
The study included the review of over 130 journals and related material.
Findings
The race to build and deliver a system for dealing with the vast increase in OA-deposited manuscripts in the USA continues. Public access to publishers’ e-content is being made available in UK public libraries as part of the Finch report agreement. More developments in Patron-Driven Acquisition are described and much else.
Originality/value
Represents a useful resource for librarians and others concerned with interlending and document supply and such related matters as resource sharing and open access.

Abstract
Purpose
The purpose of this paper is to provide a review of the literature concerning interlending and document supply.
Design/methodology/approach
The paper is based on the reading of over 130 journals and related material.
Findings
Some interesting findings on document supply including an important Outsell report on document suppliers and some research showing that whilst users expect and often make do with what is immediately available, nonetheless over half of the responders use document supply services. Some substantial pieces are reviewed on Big Deals including the dramatic growth in deposits as a result of toughening up the NIH mandate and some further articles on the UK Finch report on open access. The significant developments in Open Access are reflected once again in a lengthy section in this review.
Originality/value
The paper represents a useful resource for librarians and others concerned with interlending and document supply as well as such related matters as resource sharing and open access.

Design/methodology/approach
A review based on the reading of over 150 journals and related material including reports, conferences and blogs.
Findings
This review has concerned itself primarily with the recent developments in open access and the impact that these will have on document supply. However some articles of importance in document supply as such have been noted.
Originality/value
This paper represents a useful resource for librarians and others concerned with interlending and document supply as well as such related matters as resource sharing and open access.
