The major and most important part of the book collections of the University Library (UB) is arranged systematically, according to an objective structure.
In German university libraries the most commonly used structure is the so-called "Regensburger Verbundklassifikation" (RVK)" which arranges books according to the system of sciences. Accordingly, each subject is divided into a number of main groups which are – for their part – subdivided in factual subgroups and further in specific groups. Each book is assigned to a very specific place within the scheme based on the content of the book, which is to be found in the book number in form of the “place in the scheme”.
2. Structuring and sequencing of subject groups
A brief summary of the shelf classification is presented covering the 17 subject groups for books in UL. The sequence is given by the so-called location identification numbers. Monographs and journals are also placed according to location and subject group.
3. The structure of a shelf mark
For the structure of a shelf mark or the holdings systematization within, a subject applies the following organizational principle:
|Place||Subject Group||Classification mark||Alphabetical sorting||Volume||Edition||Book|
Place and shelf group:
The place indicates the shelf group where the book or the journal can be found. As a rule, a pair of locations covers one subject group: The locations 46 and 47 cover, for instance, literature of the subject group Economic Sciences (WIR) and the locations 51 and 52 refer to literature for Computer Science (INF). Books and journals are positioned according to subjects consecutively.
There are some places with literature referring to several subjects: in the textbook collection (locations 73, 75, 77, 79), in the media center (locations 81.X), availability of periodicals and journals referring to technical standards (locations 70, 71) and large formats (locations 100, 101, 102).
Book with an even location identification number, e.g. 20 or 46, may not be borrowed and can only be used in the library rooms (e.g. reference books). Books with odd location identification numbers e.g. 21 or 47 may be borrowed.
Theabove mentioned example of the classification mark QP 829 covers the main group Q (Economic Sciences), the subgroup P (General Business Administration) and the fine group 829 (Accountancy).
Alphabetic sorting within a classification mark:
Using a coding scheme for sorting helps to arrange and organize books in alphabetic order according to authors or titles within a classification mark.
The volume count is started by a hyphen, e.g. -5.
The notation of the edition only starts with marking the second edition given in round brackets.
The counting of the copies starts with the plus symbol: +2 means the 2nd copy.
4. Survey of the subject groups and the classification marks
The following table offers the locations, subject groups and classification marks. A more detailed list of RVK you can find here: http://rvk.uni-regensburg.de.
