BIOSIS Previews ® encompasses the entire field of life sciences and provides comprehensive coverage of the world’s published biological and biomedical research. This includes traditional areas of biology, such as botany, zoology and microbiology, as well as experimental, clinical and veterinary medicine, biotechnology, environmental studies, and agriculture. Interdisciplinary fields such as biochemistry, biophysics and bioengineering are also included. More than 6,500 serials are monitored for inclusion. In addition to full-length research articles from serials, and database also cover national and international meetings, reviews, technical letters and notes, meeting reports (from 1989 to present), software (1992 to present), and books.

The BIOSIS Previews ® (1969 to present) database includes the contents of BIOSIS print publications:

From July 1976 to December 1993, 100% of articles cited in Biological Abstracts have abstracts. These citations make up 50% of the BIOSIS Previews database for that time period. From January 1994 to present, only 75% of articles cited in Biological Abstracts will have abstracts in BIOSIS Previews. From 1985 to present, all main book records in Biological Abstracts/RRM have abstracts in BIOSIS Previews.

The BIOSIS Previews ® database is updated weekly

Controlled Vocabulary

The Controlled Vocabulary (Authority File) contains lists of the controlled vocabulary terms used in BIOSIS Previews, Biological Abstracts and Biological Abstracts/RRM databases from 1993 forward. In most implementations of the databases, controlled vocabulary terms are accompanied by information including Broader and Narrower Terms, Related Terms, Used For Terms, and Scope Notes.

Segments and Years of Coverage

The BIOSIS segmentation changes each calendar year, due to special considerations for this database. Contact Ovid Support for segmentation information for your jumpstarts.

The limit of databases that you can select for a multifile search session is based upon database segments rather than actual databases. The Ovid multifile segment limit is set at 120 to avoid impacting your search sessions. Until 2026, your BIOSIS subscription will not amount to more than 51 segments.

This database is updated online weekly.

The Abstract (AB) index contains the abstract text as provided by the author of the source document. BIOSIS editors provide abstract text for book main citations, those which describe the book as a whole, and for meeting summary and main cite items, which describe the meeting as a whole.

The abstract index contains all searchable words from the abstract. You may also notice literal representations of symbols. These abbreviations were enclosed in periods prior to 1994, for example, .tbd. (= triple bond). You will find a list of these literals in the BIOSIS Search Guide.

Note: also that the character string GRAPHICS appears in place of chemical structures, mathematical formulae and other special symbols which cannot be displayed.

The Author E-Mail (AE) index contains e-mail addresses of the source document authors. Each e-mail address element is separated, so your search should include as many elements as possible (e.g., jane, smith, villanova, and edu). Author EMail information displays in the Author (AU) field.

Note: this field is not available in the BIOSIS Previews® Archive.

All Fields (AF) is an alias for all of the fields which occur in the source documents, including value-added fields such as Abstract (AB).

The Accession Number (AN) index contains a unique identifying number for each item.

The Accession Number is composed of three elements: a product identification code, product year, and an item number, i.e., PREVYYYYnnnnnnnn.

The Author/Editor/Inventor (AU) index contains the author name(s) or organization responsible for the source document. Author role and e-mail information is not present in the index but will display in the record. The format for authors is last name followed by first name and/or initials: Smith James or Smith J.

Enter the last name, or if it is a common name, enter the last name and first initial. If you are unsure of the spelling of the last name (macdonald or mcdonald), enter one version and then scroll through the list of names to find the other.

The Biosystematic Codes (BC) index contains the BIOSIS Biosystematic Code for an organism(s) and the corresponding organism classifier discussed in the source; document. The Biosystematic Code will be presented in brackets ([]) followed by the organism classifier. The classifier may also be followed by new taxon, which identifies when new taxa are discussed in the source item.

You may search Biosystematic Codes by name or code; you may also add "new   taxon" to each (for example, muridae new taxon.bc. or 86375 new taxon.bc.).

Note: the Biosis Previews Archive does not support the use of "new taxon," which is only available from 2003 onwards.

The Book Author/Editor (BE) index contains the authors name or an individual organization responsible for the source book. The role of the author is not present in the index but will display in the record. Book Author/Editor coverage begins in 1993.

The format for authors is last name followed by first name or initials: Smith James or Smith J. Enter the last name, or if it is a common name, enter the last name and first initial. If you are unsure of the spelling of the last name (macdonald or mcdonald) enter one version, then scroll through the list of names to find the other.

The Original Language Book Title (non-English) (BO) index contains the non-English title and subtitle of a book. This field will not appear if the source book was published in English or, in the case of titles published in multiple languages, the English language version was the one processed by BIOSIS. Original Language Book Title coverage begins in 1993.

This field displays as part of the Source (SO) field.

The Book Title (English) (BT) index contains the English-language version of the book title and subtitle. Literalizations are substituted for special characters and symbols. If the Book Title is the result of a BIOSIS translation of a non-English title, it will appear in square brackets ([]).

The Book Title (English) field displays as part of the Source (SO) field.

The BIOSIS Update (BU) index contains the day the item was originally produced by BIOSIS. For items produced 1969-1998, BIOSIS Update contains only the year of production; for items produced 1999-present, BIOSIS Update contains the month, day, and year of production.

This field displays as part of the Update Code (UP) field.

The Chemicals & Biochemicals (CB) field contains the name of a chemical or biochemical which is described in the source. Each Chemical/Biochemical name could be followed by one or more of the following modifiers:

The modifiers are individually added to the terms to create phrases, as well as being indexed separately. You can search for individual terms or search for terms and modifiers as phrases.

For example, if the source data is "p38 kinase: 165245-96-5, regulation", you can search the phrase "p38 kinase.cb." or "p38 kinase regulation.cb." to ensure that the modifier "regulation" refers to the term of interest. You can search the modifiers separately, or search a term and modifier as a phrase (as above) to ensure the accuracy of your search.

CheckTags are frequently searched terms that have been identified to bypass the mapping screen to help the searcher get to the results faster. BIOSIS Previews checktags terms includes the following:

The Ovid search engine applies so called "run-time stopword processing". This means the search engine on the fly ignores the stopwords: and, as, by, for, from, in, is, of, on, that, the, this, to, was, were & with.

Therefore a search: at risk for diabetes.ti will also find: at risk of diabetes. The distance of one word in between is kept, but the stopword "for" is ignored.

Abstract 
  The description of a new species and the redescription of four species of the genus 
  Deuteraphorura are given. Deuteraphorura caprelleana sp. nov. is characterized by 
  the peculiar distribution of dorsal (32/033/33354) and ventral (3/011/3212) pseudocelli 
  that allow to recognize it from the other congeneric species. Furthermore, four species, 
  Deuteraphorura apuanica (Dallai, 1970), D. pseudobosnaria (Dallai, 1970), D. 
  pseudoinsubraria (Dallai, 1970) and D. pseudoghidinii (Dallai, 1969), are redescribed 
  based on type and new topotypic material to furnish the description of some characters, 
  especially concerning the chaetotaxy, not considered in the original description. 
  A proposed key to the italian species is also reported.

Abstract  
  A brief survey of Heptageniidae (Ephemeroptera) from Thailand and Malaysia is presented. 
  New for science are Afronurus namnaoensis sp. nov., Compsoneuria langensis sp. nov., 
  Epeorus inthanonensis sp. nov., Epeorus (Belovius) khayengensis sp. nov. and Epeorus 
  nguyenbaeorum sp. nov., from Thailand and Compsoneuria perakensis sp. nov. from Malaysia; 
  the new species originate from rivers and streams in the north of Thailand and from some 
  streams in peninsular Malaysia. For the first time, the male of Asionurus primus Braasch 
  & Soldan, 1986 is described and a larva of supposed Iron longitibius Nguyen & Bae, 2004 
  is illustrated from Thailand. Compsoneuria (Siamoneuria) kovaci Braasch, 2006 was 
  originally not adequately placed in Compsoneuria Eaton, 1881. Its true affiliation 
  remains unclear. Supposed Epeorus hieroglyphicus Braasch & Soldan, 1984, redescribed by 
  Nguyen and Bae (2004), is renamed to Epeorus nguyenbaeorum sp. nov. Two new findings of 
  Heptageniidae are reported from Thailand: Epeorus bifurcatus Braasch & Soldan, 1979 and 
  Iron martinus Braasch & Soldan, 1984. Rhithrogeniella ornata Ulmer, 1939 is recorded 
  from Malaysia for the first time.
