Symbols:

	This resource was revisited and/or updated within the last four weeks.
	A new resource added to the MathDiss database database (usually within the last four weeks). A list of all new resources in the MathDiss database is available.

How to use the MathDiss Database:

(1) Select preferred mode of entry
There are three entry modes to access the contents of the MathDiss database.

• A SUBJECT catalog provides an overview of resources by the Mathematics Subject Classification.
• An INDEX SCAN offers the option to browse in the entries in an alphabetical order.
• Finally, a LOCAL SEARCH engine enables users to enter keywords (e.g. creator names, resource titles, keywords, etc.) and launch a search.

(2) Response of the system: The Mini- Templates
Depending on your preferred entry mode, the system will respond with different screens. In any case, it will present a list of results. After selecting an entry from the SUBJECT catalog or an entry with multiple occurences from the INDEX LIST, the results will be presented in the form of the so-called Mini-Templates with information on title, identifier and evaluation. The following example shows an entry of one of the Mini-Templates:

1. Families of Curves with Prescribed Singularities
Author	Thomas Keilen
MSC	14H10;14H15;14H20;14J27;14J28;14J70
Keywords	singularities; equisingular families; projective surfaces (English)
Info file	http://kluedo.ub.uni-kl.de/Mathematik/Metadaten/dissertation_3.html

(3) Select the resources which appear promising or interesting
The responses to your query are displayed in a list of Mini-Templates by alphabetical order. On the basis of this list users can select the resources that seem to be most promising or interesting. There are two options for further selection:

(3a) More detailed information on each resource
There is more detailed information on each of the resources indexed in the MathDiss database (specifying additional metadata elements such as creator, publisher, access information, rights etc.). This information is available in the so-called full Metadata Template and is accessed via the metadata link in the title bar of each Mini-Template entry. This full template is meant to provide more comprehensive information on a resource without actually loading it; its categories are based on the Dublin Core Metadata Element Set.

(3b) Without a closer look at the metadata
If there is no need for a closer look at more detailed metadata, any resource is directly accessible by following the hyperlink in the identifier (URL) field (info file or source file) of the Mini-Template.

(4) Access to a resource
No matter whether from the Mini-Template or from the full Template, any resource can directly be accessed by activating the hyperlink in the identifier field.

SUBJECT CATALOG

The Subject Catalog organizes the data in the MathDiss database according to the Mathematics Subject Classification (MSC). There is an online version with search option of this classification available.
The two reviewing journals "Mathematical Reviews" (MR) and "Zentralblatt für Mathematik und ihre Grenzgebiete" (Zbl) have finalized a revision of the MSC. The MathDiss database will move to the new MSC 2000 as soon as we have the resources to change the entries.
If you are not already familiar with the Mathematics Subject Classification we recommend that you take some time to study the structure and contents of the Subject Catalog.

INDEX SCAN

The Index Scan provides a sorted view of the different indexes in the MathDiss database. The indexes are:

Title

The full title of the dissertation

Title words

Words occuring in the full title of the dissertation

Text

Any words occuring in the description dissertation (title, names, abstract etc.)

Keywords

Keywords attached to the dissertation. Note that keywords may be comprised of several words, like "algebraic geometry".

Persons and Institutions

Persons (author, advisor, referees) and institutions (university, library) involved in the production of the thesis.

Authors

Complex entries of authors of the thesis

LOCAL SEARCH

The MathDiss database is equipped with a local search engine (based on our Avanti server) that searches the database, a simple and an advanced search function are available.
Generally all searches can be truncated with a question mark (?) at the end. This will find any expressions starting with the stem before the "?".
The display of the search result can be chosen as:

• Only count of the results
• Title (linked to the full metadata template)
• Title and URL (linked to the full metadata template and the source respectively)
• Mini template (all respective links)

The display can be sorted according to:

• Title (ascending alphabetically)
• Subject Classification (by the respective code)
• Source Date (descending by last update of source, i.e. newest are top)
• SSGFI Timestamp (descending by last review of source, i.e. newest are top)

Simple Search: Search in only one category.

Advanced Search: Combines several search options with Boolean operators.

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 or date. 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".

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.

Date

This is date the source was entered into the MathDiss database. Note that dates are given as 8 figures representing the year, month and day (yyyymmdd). If you use e.g. the truncation 200109?, you can find all dates from September 2001.
