1 Pollution Abstracts. 1 von 8

2 Content: This database provides fast access to the environmental information necessary to resolve dayto-day problems, ensure ongoing compliance, and handle emergency situations more effectively. Pollution Abstracts combines information on scientific research and government policies in a single resource. Topics of growing concern are extensively covered from the standpoints of atmosphere, emissions, mathematical models, effects on people and animals, and environmental action in response to global pollution issues. To ensure comprehensive coverage, material from conference proceedings and hard-to-find documents has been summarized along with information from primary journals in the field. Serial Sources List: Subject CoverageMajor areas of coverage include: Air Pollution Marine Pollution Freshwater Pollution Sewage and Wastewater Treatment Waste Management Land Pollution Toxicology and Health Noise Radiation Environmental Action Dates of Coverage: current Update Frequency: Monthly, with approximately 1,190 new records added Sample Record: 2 von 8

3 Field Codes The following field codes are found in the records of this database. Here they are listed in alphabetical order by two-letter code. See Field Codes and Search Examples for detailed descriptions and search examples. 3 von 8

4 AB = Abstract ab=(global warming) and ab=(north america or canada) The abstract includes key points of the source article. Most records have abstracts and when available, authors' abstracts are used, although they may be edited to CSA style. Every word is searchable; however, to find precisely what you want, use only distinctive words and phrases. AF = Author Affiliation af=bremen af=(virginia and marine science) This contains the organization name and address for, usually, the first-listed author, or for the author name that has an * beside it. This address is taken from the source document and is normally the address for correspondence with the author(s); however, the affiliation may have changed since the original document was published. Common words such as "National" or "University" may or may not be abbreviated, so avoid searching for these and instead use the more distinctive parts of the name AN = Accession Number an= This is a unique number assigned to each record. In some databases it is a 7-digit number and to retrieve the record with that number all 7 digits must be entered, including any leading zeros. AU = Authors au=jackson, tm au=gray-owen, SD This field contains the name(s) of the author(s) of the source document. Currently a maximum of 14 authors are listed per record, but this has not always been the case. Names are usually in the format of Author. Do not attempt to search for suffixes such as "Sr." or "III" or titles such as "Dr." -- they may not have been in the original document and even if they were, they are usually not included at the indexing stage. For hyphenated names or initials, enter the name with the hyphens. CA = Corporate Author ca=(dow corning) ca=(environmental protection agency) This is the name of the organization that has produced the original source document. This field is often present when there is no personal author field. However, for patent records, the name in the Corporate Author field is the patent holder (and the name[s] in the Author field is the inventor). To search this field use the distinctive parts of the name and do not search for designations such Corp, Co, Company, Ltd. etc. CF = Conference cf=(benthic ecology and columbia and 1996) This field provides the name of the conference and where and when it occurred; it is generally edited to CSA style, eg: 24. Annu. Benthic Ecology Meeting, Columbia, SC (USA), 7-10 Mar 1996 All these words are searchable, but for faster retrieval, ignore the common words such as "annual or "annu" or "meeting" and search for the distinctive elements only. Records retrieved include the papers presented at the particular meeting and the "master record" for the complete proceedings. If you just want the master record, use the TI= field as well, and AND the results together to produce the final result. 4 von 8

5 DE = Descriptors de=(ternary systems) or de=(phase diagrams) This field contains indexing terms taken from a thesaurus or controlled vocabulary. These descriptors may be single or multi-word terms and serve as standard ways to describe the subject of the original document. They may refer to very specific items or to general concepts; often the word or term is not to be found anywhere else in the record, including in the title or the abstract, so a descriptor provides another way, access point or search term for finding the information you want. If you are already familiar with the vocabulary used to index a particular database or can easily refer to it, searching this field retrieves focused results. To search it use DE= and when looking for several multi-word terms, use parentheses around each term and the Boolean OR between. ED = Editor ed=(boxshall, GA and Schminke, HK) ed=(boxshall and Schminke) In most CSA databases, editors of books and conference proceedings appear in this field and are formatted in the same way as author names, ie, Lastname, AB. If the name or names are distinctive you do not need to include the initials. EM = Entry Month em=9703 and de=(earthquake engineering) This field has been added to most CSA databases in It signifies the month in which the record was made available on IDS and enables you to limit your search to a particular month or even the latest update. This is useful when you search regularly for a topic and only want to retrieve new records. The format is YYMM. Most likely a search of this field will be combined with another. IB = ISBN ib=( ) ib=( ) The ISBN is the International Standard Book Number. Its purpose is to identify uniquely a book title, an edition of a book, or a monograph produced by a specific publisher. Each ISBN number consists of ten digits separated into the following parts: Group identifier (national, geographic, language, or other type of group) Publisher or producer identifier Title identifier Check digit You must search for them exactly as the numbers are grouped, with or without the hyphens. ID = Identifiers id=(exxon Valdez) id=(atomic force microscopy or afm) This field contains subject terms not included in the controlled vocabulary but considered by the indexer to be extremely relevant to the record. They may be single word or multiple word terms. Since identifiers are not selected from the controlled vocabulary, different synonyms for the same subject may appear in this field, as well as abbreviations and acronyms. Also, company names, trademarks, the names of legislative acts, government policies and new and up-coming methods and procedures are often assigned as identifiers. Like descriptors, these terms may not appear in the title or abstract, and therefore serve as additional ways to focus your search. 5 von 8

6 LA = Language la=german This indicates the language(s) of the original source document. If there is no language field in the record, it can be assumed the original text is in English. The full name of each language is searchable. NT = Notes nt=price This field contains miscellaneous information such as explanatory information, ordering data, price, scale of maps, number of references in a bibliography and, in some older records, patent numbers and classification codes. The field is meant for display purposes only. NU = Other Numbers nu=(4,954,439) This lists any type of bibliographic number attached to a document that is not already in its own field. It can include report numbers, patent numbers, dissertation codes, and for older records, even ISBNs and ISSNs. Formats of such numbers have not been standardized and are not predictable, therefore this is not a good field to try and search. Its purpose is to display additional valuable information. OT = Original Title ot=(colada continua) ot=poisson The non-english language title from the source document appears in this Original Title field if the title is in a Roman alphabet. Title translations appear in the Title, TI= field. No diacriticals are represented. PB = Publisher pb=(john wiley) This field typically occurs when the item indexed is a book or monograph, although increasingly, more records where the source document is a journal article, have this field also. The Publisher field includes the name of the publisher and the place of publication. PT = Publication Type pt=(journal and review) Records are categorized by the generic type, physical form or medium of the original source document, such as "Journal article", "Conference" etc. Bibliography Book Computer file [infrequent] Conference Dictionary [infrequent] Dissertation Drawing [infrequent] Film [infrequent] Journal artiche Law or statute Map Monograph Numerical data Patent Report Review 6 von 8

7 Sound recording [infrequent] Standard Summary [ie, source document is abstract only] Training manual [infrequent] There can be more than one publication type listed. SF = Subfile Name sf=(marine biotechnology) and seaweed A subfile name corresponds to the print product (ie, the abstracts journal) in which the record originally appeared. A few subfiles exist only as archives because the print equivalent is no longer published. SL = Summary Language sl=(french or spanish) This field indicates the language(s) of abstracts printed with the source document. Often, if the abstract is only in English, then no summary language displays. SO = Source so=(j. FISH BIOL.) This field contains bibliographic citation information. If the record describes a journal article, the source field for most CSA databases contains the abbreviated journal title. To search for a particular journal title you must therefore know the abbreviation name. To find the correct form of the abbreviated name, search the Serials Source List for that database. TI = Title ti=gibbs energy and nickel chromite ti=(organic chlorine or chlorinated dioxins) and (lake sediments) This field contains the title of the source document in English. Non-Roman titles are transliterated into English as well. Non-English titles appear in the Original Title, OT=, field. Hint: when mixing Boolean OR and AND in the same search statement, it is good practice to enclose the words or phrases in parentheses so the correct terms get ORed and ANDed together. In the last example above, you want to make sure that the "organic chlorine" gets ORed with "chlorinated dioxins" and the result ANDed with "lake sediments" rather than have "chlorinated dioxins" ANDed first with "lake sediments" and then that result ORed with "organic chlorine" -- the final retrieved results would contain many irrelevant records that would have nothing to do with lake sediments. TR = ASFA Input Center Number 7 von 8

8 Locating Documents The Check Your Library feature allows you to search for a document within your library's online catalog. Citation information is displayed by field with selection boxes to the left of the field type. There are four possible search fields to use in locating a document: source, ISSN/ISBN, title, and author. Not every record will contain all four of these fields, and the default search field is the source field. The content of the field text boxes may be edited before executing the search. Retrieval of electronic Full-Text is available only if your library has a subscription to the online journal. A hyperlink to the full text provider(s) will be in the box to the right of the acquisition option if it is available through your institution.
