Library identifier
The library identifier has seven digits and uniquely identifies each library. The leading digits stand for the body the library belongs to; the remaining digits come from that body's own numbering — a membership, customer or school number. The sections below are ordered by that body: once a library has found the section it belongs to, everything it needs for its identifier is in that one place.
Catholic libraries#
| Starts with | Library | Remaining digits | Example |
|---|---|---|---|
1 |
library of the Borromäusverein | digits 2–7: six-digit membership number with the Borromäusverein | 1140360 |
20 |
library of the St. Michaelsbund | digits 3–7: seven-digit membership number with the St. Michaelsbund without the leading 70 — or the five-digit library number, which is the last five digits of the membership number |
2010360 |

The identifier starts with 3. Digits 2 and 3 name the regional body:

School libraries#
| Federal state | Starts with | Remaining digits | Example |

digits 2–7: six-digit school number, that is the eight-digit office number without the leading 04 |

Library with a DBS-ID#
Libraries holding an identification number of the German library statistics start with
9. The DBS-ID consists of two letters and three digits: the two letters are converted
into a three-digit number with leading zeros, as follows: AA=001, AB=002, AC=003 …
ZY=675, ZZ=676. The three digits of the DBS-ID are taken over unchanged.
The DBS-ID ZY432 therefore becomes the identifier 9675432:
9 675 432
│ │ └── the three digits of the DBS-ID
│ └────── the two letters as a number (ZY = 675)
└──────── library with a DBS-ID
Other libraries#
If none of the bodies above applies, the identifier starts with 21. Digits 3 to 7 are
then the five-digit customer number at bibservice/IBTC — customer number 99 thus becomes
the identifier 2100099.
