Schematic Overview Forestry Guide (14k)

How to use the Forestry Guide:

(1) Selecting the mode of entry
There are three modes of entries to access the Forestry database: the Source Type Catalogue offering the formal criteria (e.g.organizations and societies, data collections, virtual libraries etc.), the Subject Catalogue,displaying a subject specific overview of Forestry, e.g. the CABI Classification for Forestry and finally the Local Search (simple mode or advanced mode), from where the entire Guide can be searched in Basic Index (e.g. author, title, keywords etc.).

(2) Response of the system: The Mini- Templates
Depending upon the mode of entry, the system will respond with different screens. In any case, it will present a list of results. On selecting an entry from the Source Type or Subject Catalogue, the results will appear in Mini-Templates with information on title, identifier and evaluation. The following example shows the template for a forestry resource which provides access to the full details of any European country's Forest Scorecard 2000 results:

5. European Forest Scorecards 2000
Subject Class Forests and Forest Trees (Biology and Ecology); Silviculture and Forest Management
Source Type Organizations and Societies

Contentsgood Clarityfair Indexfair Linksnone Metadata

(3) Selecting the resource(s)
Responses of the queries are displayed in a list of Mini-Templates in alphabetical order.Out of this basic template list, the user can select resources which are most relevant and interesting to him. There are two options for further selection:

(3a) Detailed information on resource(s)
Each resource in the Forestry Guide is indexed with additional datafields. (e.g. editor, distributor, publisher, short description of the content of the site, access information, evaluation etc.).This information is available in the Full Metadata Template and can be accessed via the metadata button in the lower right of each Mini-Template. This full template is to provide comprehensive information on a resource without actually overloading it; its categories are based on the Dublin Core Metadata Element Set.

(3b) Direct access
If there is no need for a detailed metadata, any resource can be accessed directly through the hyperlink in the identifier field (URL) of the Mini-Template.

(4) Accessing the resource(s)
By activating the resources's URLs, either of the Mini-Template or of the Full Template, any resource can be accessed.

SOURCE TYPE CATALOG

The Source Type Catalog organizes the entries in the Forestry database according to the formal classification of the resources ("source types"). There are four main categories:

1. Information Providers/Servers
Typically, resources in this group do not contain information per se. Rather, they serve as a gateway or point of entry for further research.
2. Factual Reference Works
This section includes those resources which provide direct factual references. In contrast to the resources classified under the section above, the user will be directly lead to specific sources.
3. Bibliographic Resources
In this section, the various bibliographic sources are grouped. In contrast to the entries in other sections, the user may also be directed to linklists.
4. Primary Information Sources
This group comprises resources which feature primary information.

SUBJECT CATALOG

The subject catalogue is meant to cover the respective subject areas which are relevant to Forestry. CABI subject category codes and CAB Thesaurus descriptors are derived from the CABI Classification Scheme (CAB International) used in the AGRICOLA Database (National Agricultural Library) of the United States Department of Agriculture and in the AGRIS Database (FAO, Rome), with a slight modification to allow for differences in subject scope and emphasis. CABI subject category codes have been applied to records to index broad subject areas, and consist of two characters and three digits (KK100). For full details of the subject coverage, users should consult the online version. Cabi subject category codes enable searchers to locate general subject categories which are not easy to retrieve using descriptors alone, thereby helping them to exclude irrelevant information from their searches.

LOCAL SEARCH

The Forestry Guide is equipped with a local search engine (based on our Avanti server) which searches the database in simple or in advanced mode.
Generally all searches can be truncated with a question mark (?) at the end. This will find any word starting with the stem before the "?".
The display of the search result can be chosen as:

The display can be sorted according to:

Simple Search
Search in only one category.

Text
Text searches for the entered term in all fields containing text, e.g. author, description, clasification. It does not search in non-verbal fields like URL, date, evaluation. This search is case-insensitive, and if you enter several words, they will be concatenated with "AND".
Title
Title performs a case-insensitive search in the Title field, several words will be concatenated with "AND".
URL
URL separates the entered address: the server addresses at every "." and the paths at every "/". These parts are joined with "AND" and are searched in the URL field So you can enter only parts or pieces of the address. This search is case-sensitive. If you enter e.g. "emis" you will find all data sets refering to sites on the EMIS (European Mathematical Information Service) Server with the URL http://www.emis.de/.
Keywords
Keywords performs a case-sensitive search in the Keyword field, several words will be regarded as one expression, e.g. "algebraic geometry" will find all entries with this keyword, while "algebraic?" will find additional entries.

Advanced Search
Combines several search options with Boolean operators and allows, for instance, for searches for an English language site containing the keyword "algebraic geometry".
In Advanced Search, the following categories are further available:
Codes: Codes are case sensitive and have to be entered according to special tables.

Language
Two lowercase letters, according to ISO 639-1, e.g. en for English, de for German, fr for French.
Country
Two capital letters, according to ISO 3166, e.g. GB for Great Britain, DE for Germany, US for the United States of America.
CABICODES / CABI Descriptors
Cabicodes have been applied to records to index broad subject areas within which they fall, and consist of five characters, two identical alphabetic characters and three digits (KK100). For a precise entry, see the online version.
Source Type
Two to 7 lowercase letters as described in the Source Type Catalog.

Dates: Dates are given as 8 figures representing the year, month and day (yyyymmdd). If you use e.g. the truncation 199909?, you can find all dates from September 1999.

Last Update
This is the last time that the source was updated when it was described.
Time stamp
Timestamp searches resources added to the guide within a certain timeframe.
